Ford F-150 (2004-2008) :: Hubs Won't Engage Only Make Grinding Noise?
Nov 28, 2011
I have a 2005 F150 113,000 FX4. When I put the truck into 4x4 high the light comes on and the front driveshaft engages. Same with 4x4 low. the problem is that the hubs never actually lock. When I move forward in some mud or wet grass the right front hub makes this grinding noise like it is actually trying to engage but never does. Same with 4x4 low. I do not have any weird noises when I drive in 2wd.

2004 fx4, transfer case engages, but front wheels won't engage. I assume the vacuum solenoid is stuck, any other thoughts?

Okay this is what I got; I recently purchased high mileage 2004 F250 Super Duty short box super cab 5.4 liter. Came with manual 4x4 handle on the floor so no 4 wheel on the fly and this eliminates the vacuum for the auto hubs so this will not be part of the problem. When engaging the hubs and ONLY when engaged the driver side hub grinds. The 4 wheel drive works but it sounds like its ready to grind itself into oblivion. I did pull the hub and the grinding was gone, I happen to have a spare hub that is good and the grinding returned.
I have jacked it up and made sure I have no play in the wheel itself and the axle knuckle on the axle shaft. Some say remove the front drive shaft? Or turn the wheels all the way in one direction engage the hubs and check for binding? I will do this in the morning, but what does that confirm if it not the hub. Could it be the passenger side echoing across? On my 99 Super duty I kept hearing moaning coming from up front like the breaks were shot and if you stuck your head out the window it was the back echoing to make it sound like the front.

I recently purchased as used 2006 F-150 Lariat 4x4 with 77K miles. I am having an issue with the shift on the fly, I had a vacuum leak that was causing the auto hubs to make noise on occasion but it has never allowed me to shift from 2wd to 4H while moving. I have replaced the IWE solenoid and repaired the vacuum leak but it still will not engage while moving. The light for 4H comes on but the hubs will not engage. The dealer where I purchased the vehicle is not a ford dealership and whey have been trying to solve the problem but to no avail.

About a month ago I bought a 2004 F-250 160xxx from a reputable Ford dealer here in town. The dealer performed a safety and emissions inspection, and spent about a grand on other repairs, as a condition of my purchase. Today I had it in the shop for an instrument cluster issue (at a different Ford dealer, closer to my house), and was told the vacuum lines were all messed up. Their write up is below:
"Check 4x4 operation. Transfer case shifts to 4x4 and 4x4 low. Front hubs do not engage automatically. Check vacuum at the hubs. No vacuum. Check the vacuum at the solenoid. No vacuum. Perform visual of the engine vacuum lines. There is no vacuum to the reservoir. Vacuum line is routed wrong from the fuel pressure regulator to the vapor management valve. There is other vacuum concerns. All of the vacuum line routing needs to be inspected and corrected."
The service rep told me it is questionable whether the 4x4 ever worked, although during the few weeks I've owned it, I could hear gears or other mechanical parts making noise which seemed to me to be in response to me turning the 4x4 electronic switch. She also said there was a vacuum line dangling loose with a screw in the end of it.
Before I contact the dealer where I bought the truck, I am planning my going-in position. But I wanted to get a sense of a) how serious of a problem this might be? and b) how reasonable it is that the dealer didn't catch this issue before I bought the truck while they were in their fixing other things?
The dealer who sold me the truck made it very clear that the sale was as-is, and I took it to my mechanic prior to purchase, though unfortunately he only had time for a cursory look at the engine. Obviously he didn't look closely enough to find this issue.
I'm not sure if I should ask the dealer who sold it to me to fix it, or ask them to allow me to return it, or sell it back to them, or if I should eat the cost of fixing it. How wrong would it be to try to trade it in for something else?

I have a problem transfer case 2006 f-150 , it tries to engage once in a while as I am driving and makes a terrible noise . I pulled the vacuum lines off at the hubs on each front hub and it stopped trying to engage. What the problem could be ?

Having an issue w/ my 00 550. When I lock in the hubs there is instantly a noise, More of a squealing then a grinding. The truck goes in and out of 4x4 no problem and the noise is there locked in 4x4 and not locked in, as long as the hubs are locked in. I can't tell if the noise is coming from the 4x4 driveshaft but there is no noticeable play in the u-joints or the u-joints in the front axle. I did notice when I spin the 4x4 shaft by hand the passenger side joint spins slower then the driver, not sure if that's normal or could be the problem.

Read everything I could and couldn't find a problem/solution similar to mine:
- Replaced broken (in three pieces) actuator on driver's side. Also replaced hub assembly (bearings went bad). Afterward started getting the grinding noise all the time in 2wd that goes away in 4HI.
- Replaced the entire hose assembly since I was not getting vacuum at driver side end hose. Still wasn't getting vacuum, turns out passenger side actuator diaphram was completely torn up as well (checked vacuum with hose on passenger actuator, not removing and plugging like I should have), so replaced the passenger side actuator too.
- Driver side grinding noise went away completely, now getting grinding noise on passenger side ONLY WHEN PRESSING ACCELERATOR. Take foot off accelerator and coast down road/highway noise goes away. Noise also goes away when putting truck in 4HI.
My latest actions: I've checked vacuum at both ends of hose while someone in park throttles truck up to 3k rpm, vacuum doesn't appear to change at either hose end while opposite side is attached to its actuator. Replaced passenger side actuator again thinking the first was defective, no change in grinding noise. Greased ring on wheel hub where actuator attaches thinking I was getting a leak at the actuator/hub seal, no change. Still only a grinding noise when accelerating, not while coasting with truck running.
The perplexing part: If it is a vacuum issue, how is it I am getting good enough vacuum from the driver side but not from the passenger side, since the driver side hose connection is downstream from the passenger side? Also, how am I not seeing the vacuum drop when checking at the hose end of either side while someone throttles truck up in rpms?
My thoughts: Definitely a vacuum leak somewhere in the system, minor enough to not notice right away on gauge, thinking to check the vacuum box and check valves next. Also thinking the passenger side hose from solenoid has a small leak causing the issue on the passenger side and not the driver side anymore, so thinking of putting the old hose back in to see if there is any change (I had replaced the hose prior to knowing the passenger actuator was torn up so I am not sure if the hose is really bad).
3-piece actuator I described above in picture for reference. Honestly I was not surprised, this has been my luck with this truck.

2005 ford f150 Fx4 So last Friday I started hearing a grinding noise from the passenger side front of my truck. sounded like metal on metal. So I started rooting around and noticed that bottom ball joints were shot. so replaced bottom ball joints on both side. I aslo replaced wheel bearing hub assembly on both sides, still heard the grinding. So I noticed that both axles were slinging grease, so I replaced them on both sides.
Still heard the grinding noise. So then I removed everything from the passenger side and noticed that the locking hub actuator was grinding both axle and the wheel bearing hub. So I just got done replacing that on the passenger side, put it all back together, and still grinding noise ringtones free. Also replaced the 4wd solenoid that they said gets water in it, and I replaced the check valve. And I put new Rotors and breaks. What it could be?

Every time I brake, there is an awful grinding sound in the rear of my truck. It doesn't seem to be affecting the brake strength, however something is obviously wrong. I have looked at the brake pads and they seem to be in good shape. I am a mechanical misfit, but I hate getting ripped off by other people at the brake shops.
2005 F150 Crew Cab, 5.4 V8....

First I will start off by stating that my truck is a 2005 Ford F150 2WD Regular Cab 6.5 Bed, with the V6.
My problem is, when making a left turn at low speeds, I have a grinding noise that corrects itself upon straightening out the truck. This seems to happen on turns in the parking lots etc. It almost sounds like the tires are rubbing but the tires are the same BFG's that have been on the truck for 40,000 miles and have never rubbed. I am thinking it might be the power steering pump but am unsure. I do not have access to a lift right now but I have done the shake test on all of the suspension components and nothing seems out of place or loose.

We've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..

I have an intermittent grinding noise coming from what sounds like both front wheels, it sounds like metal on metal almost like something metal rubbing the rotor but I just put new pads on and the noise was there before as well with nothing touching the rotors but the pads. The sound will appear out of no-where at low speeds of 35 or below and will continue until I brake and slow down, just before I come to a compete stop the noise will stop with a slight clunk.
I can then drive away with no noise. I am pretty sure it is not brake related except maybe ABS somehow but was also thinking front axle or diff, also have read posts that are bearing related, but both at the same time?. It is the slight clunk before stopping that I can not figure out is related to. It is an 05 f150 xlt 5.4 super cab 4wd with 85k miles

I've got a new issue that is happening on the front end of my truck. Whenever I try turning my wheel while driving, I get this rubbing/grinding noise coming from the front of my truck. It only happens when the wheels are in motion. It seems to happen less when I'm driving at higher speeds, but I can notice it make the sound at any speed. I tried driving it slowly in an empty parking lot while turning and it's definitely making the sound every time the tires rotate.
I took it in for an alignment because this was happening every time I drove, whether it be driving straight or making a turn. Now that my alignment has been fixed, it no longer make this noise if I am driving in a straight line, so it only seems to happen when I'm turning. I had the mechanic check to see if they could reproduce the issue. The mechanic was able to hear what I hear, but when he put it on the lift at the shop, he was not able to reproduce the sound.

I have a 1994 F-150 extended cab electronically activated 4x4, with the 302 V8 and an e4od transmission.
When the truck is running and it is in park or neutral it makes a grinding/whining noise and when it is in gear it doesn't engage, or occasionally will barely engage, but only enough to move it a little ways.
I've read a couple of post that suggested bad connections to the transmission could cause the transfer case to be in neutral which could cause a similar problem to this. I checked all the connection the best I could and the only thing I found that gave me any concern was one of the wires connected to the transfer case shift motor had some of the insulation melted or rubbed of and the wire was a bit corroded.
Is there any chance that this could be causing my overall problem with the truck not driving? Or what might be going on with it? Or any way I might be able to fix it without having to hand over a significant chunk of change for the full rebuild.

And the vacuum pump was replaced.

I bought a 2001 Excursion Ltd 4 years ago. A previous owner put Warn Premium hubs on it, which I would have eventually done myself.
I got stuck a couple of weeks ago and tried to use my 4wd. Nothing.
A friend suggested I replace the Transfer Case Motor as it can go out if you don't use it. I got that done today but I still don't have 4wd.
I can hear the transfer case shift and see the drive shaft spinning, but the front tires don't spin.
I thought it was the PVH solenoid, but discovered the Warn locking hubs don't use the vacuum and it has been disconnected/plugged.

Ok I have been trying to find out what is going on with my truck and I cant seem to find anything on here that points to all the symptoms I am having. I have a 05 xlt 4x4 with 5.4. For the last 5 months or so I have been noticing a slip or grinding noise when I go up a hill and it downshifts into I believe 3rd gear. It sounds like going over rumble strips on the road but only lasts a second. It also does it sometimes when I pull out from a stop.Also when I let off gas or brake to a stop it seems to shudder a bit.
Maybe its my imagination since I keep hearing for the grinding sound, I don't know anymore.Its driving me nuts(er). It doesn't do it all the time either.It has only 65,000 miles on it and never towed. I know I am due for a total tranny flush since it never had one. Could this be the whole problem? Iv been reading other stories that sound close to mine but they never mentioned about the noise when pulling out. Could it be the rear end? I am totally lost on this one.Other then that problem it runs great. Shifts nice.

I'm having 4WD problems with my Yukon, but the dealer keeps telling me there's nothing wrong with it (this has been going on for 2 winters now), which is either code for, "let's wait until it's extended warranty expires, so we don't have to pay for it," or "the computer says nothing is wrong, so that's all we're going to look at." When it's in 4WD, anytime I make a sharp turn or even turn a corner there's a grinding noise in the front, if I try to back up, it will only go as far as one revolution of the tires then stop (I have to take it out of 4WD to backup), eventually the "Service 4WD" light comes on, but apparently nothing gets recorded on the computer. It has 32,000 miles on it.

2004 Santa Fe, after starting car the brakes make a grinding noise, the nthe ABS, ESC and 4 wheel drive light come on. After the initial grinding the noise stops and the brakes work fine. Just the lights stay on.
