How tight should the wheel bearing retaining nut (sealed bearing hubs) be torqued when replacing the front rotors?
Is there a spec, or just real good and tight since the bearings are sealed units.....
I'm trying to replace the front brake rotors on a 97 Ford Explorer (AWD, 5.0 L). I've removed the calipers and pads - but can not loosen the old rotors. It looks held on by rust - but do I need a special rotor pulling tool?
View 8 RepliesThe shop replacing my front tires advised me to replace my front brakes and rotors soon. I'm not a huge car repair person, but I remembered my father-in-law saying brakes aren't that bad to work with. The car is the "college beater" I bought ten years ago and I'm trying to keep investments in it minimal. I told the shop I would do the brakes myself. So I spent the weekend with the Haynes manual fussing with overtorqued lug nuts, rusted on rotors, tightly wedged guide pins, and outer pads that didn't seem to have room (not the piston side). Got everything assembled, bled the caliper that was disconnected, and took it for a test drive.
I got about 30 feet from the driveway before pulling back in. The front of the car was making an grumble sound and had an odd vibration like a flat tire. This was with brakes engaged and not engaged. The car stopped fine, but I probably didn't get above 10 mph. Is this part of the "bedding/seating" process? I put in new (cheap) rotors and pads. This afternoon I'll check to ensure the pads are in properly and aren't dragging on the rotor and that I have the wheels properly centered. Car is a 96 Ford Escort 2 door hatchback.
I can't figure out how to get my front brake rotors off to replace them. I removed the caliper and thought the rotors should just come right off but they didn't? I then pulled the hub out and there was a retaining ring with a good size nut behind it , but you shouldn't have to remove the hubs to remove the brake rotors should you?
The stats of the truck are 04 f250 4wd w/manual hubs!
I'm working on a couple of repairs and have encountered a few questions:
1. Are the bolts supposed to come out of the top of the end link? Mine don't so I don't know if that's the way it is or mine are so far gone that they are frozen in the sleeve. My poly bushing kit does not have any new bolts so I'm hesitant to lay into it with a 10 ton press and ruin the bolts (I don't know how much they are from Ford to buy or if I can even buy them).
2. HPO rail plug. I'm removing my HPX as I'm tired of it leaking (hopefully when my HPOP comes back as a T500 I won't need it anyway). I've seen 33 ft-lbs and 96 ft-lbs. As I go towards the 96 ft-lbs it feels like I'm going to strip the threads out so I backed off and they are at 33 ft-lbs now (I don't need that headache and my wife would go through the roof). I got the ones from Riffraff as I misplaced the ones I took off 8 years ago (go figure). The HPO line connections to the head (or pump for the matter) are 19 ft-lbs. I use Loc-Tite on those but both have an o-ring (which provides most of the seal) so I'm not to keen on gronking the rail plug.
3. I'm also replacing both HPOP gaskets. I know that the HPOP and reservoir mounting bolts are 18 ft-lbs (from Ziggy. in the tech sticky) but is there a spec for the cover bolts too? I know the gasket provides the seal but I'd like to make sure that the force is distributed evenly across the gasket (Sous isn't the only OCD person around).
Hopefully this fixes most to all my oil leaks (still have to tackle the oil cooler). The valley is covered (as well as the front of the reservoir) and there is a lot of weepage on the paper towel test. There are years of buildup everywhere and will take a few tries and several cases of Simple Green to see the metal again.
I've just begun to replace my front struts (Monroe quick strut pre-assembled). The thing is, the top bearing plate bolts and the lower mounting point are out of alignment by 90 degrees. The included directions say they can be rotated but gives no procedure and they do not just "turn" easily obviously. How to rotate them to fit??

View 3 Replies I plan to attempt my first ever brake job on a 2008 Ford F-150 XL 4.2L V6 RWD with 50K miles on it.
I've done a lot of reading in order to prepare and from what I can gather it seems best to take off the brake rotor altogether in order to clean off the rust build-up and apply some nickel anti-seize compound in between the hub and rotor. I live in a cold climate and we use quite a bit of salt on the roads here so I thought while I'm changing the pads I might as well clean the rotors of all rust build up while I got the calipers off.
My only problem is that I only have a 265 foot pound torque wrench and the spindle nut that holds my rotors on calls for 295 ft. pounds torque. Also the Haynes manual says that you should buy a new spindle nut ($20 part) and cotter pin. I have neither.
So...I am wondering whether I should forestall taking off the rotor and just do some surface clean-up of the rotor with some Evapo-Rust Rust Remover then blast it with some Brakleen and call it good. I plan to use some caliper grease of course and a dab of nickel anti-seize compound on the backsides of the new brake pads. Is this bad practice, will I regret this in 50K more miles when the wheel hub is completely married to a rotor? How likely is that do you think?
I have to replace the torque strut mount in my 2008 Avalon XLS V6. I can't find the torque specs for the two bolts in my Haynes manual or at any online sites. Also, should I use either threadlocker or anti-seize on them?
View 1 RepliesI had a realization the other day, based on a Porsche 944, that the "set screw" holding brake rotors are more for the assembly process but are not actually what accounts for the fastening of the rotor on the hub. instead, the 130 Nm torque on the five wheel nuts that sandwich the rotor between the hub and wheel do this. If the torque on the nuts is uneven, but the assembly is otherwise secure, wouldn't one prediction of this be uneven brake rotor wear?
View 10 Replies08 XLT 4x4 Had a rotor slid freeze up last fall and eat a rotor. 39000 miles. Took apart and cleaned up and lubed, new pads and rotors both fronts. Now have pulsating pedal at 48000. Do the rear might need attention now or still the front? I never use the E brake.

View 2 RepliesI am finally getting around to changing the trans fluid on my 05 f150 5.4 4wd xlt auto, what is the torque value for the trans pan bolts.
View 1 RepliesI highjacked another thread yesterday but didn't get many responses so I thought I would start a new one... I've done some searching here but no one had any real answers or had a different reason for the vibration...
We have a stock '05 F150 with 24k mi that is having Vibrations not related to bad tires or a bad trailer. It rattles any cups or change that is in the center console area and the dashboard. It seems to come up through the floor.
Symptoms timeline:
The rear pops when you turn tight in a parking lot. I've been told this is normal because of the ratcheting LSD? Is this true?
The tranny fluid was low and we could not find where it was going. Put several qts in it and finally took it to the dealer where they replaced the bad seal between the transmission and transfer case. So we know they took the driveshaft out and the transfer case. Not sure if they dropped the transmission out.
We have a vibration from about 40mph-55mph under medium-full throttle. A lot worse when towing. Put it in neutral and it goes away. Rev the motor and you don't feel it. Only happens under load. Happens in 3 and 4th gear. Goes away once the torque converter locks up.
Am I going down the right path in saying it's a bad torque converter?
My 2006 F150 King Ranch 90K 5.4 lags both torque and power in addition to only 11-12 MPG
In the city it does not bother me to much but when on the highway trying its very annoying. I used to have 2005 F-150 before so I know the difference. When I accelerate its ok but lags some serious power especially at high RPM. but without any hesitation. When I try to tow my trailer or go uphill it has no torque. I still haven't tried a dyno reading
Note: The engine runs smooth, no misfires or shows no codes. The only codes I got before was for the evaporation system but disappeared after I replaced the Fuel Pump Driver Module
Now I already replaced the: Spark plugs, mass airflow sensor, cats, air filter, fuel filter + fuel pump driver module, bought another tuner. I even took it to the dealership without any findings
Now I am beginning to think if the engine timing could be slightly wrong. I just can't figure out what it is if it throws no codes and runs perfectly smooth. It's just like it's not getting enough air or fuel but without any hesitation or misfire.
I bought an 07 F150 5.4 4x4 with 135k on it about 6 months ago. Shortly after buying the truck I began experiencing a shudder when lightly accelerating up a hill. Also when accelerating hard it would misfire. Thinking that it was plugs or COPs I changed the plugs and coils. That fixed the missfire issue but it still shuddered when accelerating up a hill.
I decided to take it back to the used car dealer where I bought it so they could fix it. On the way there the fly wheel broke. The dealer replaced it and thought that it was the cause of the problem but on the way home I still experienced the shudder. I took it back and they "scoped" it and found that the torque converter was bad. They replaced the TC and now there is no more shudder BUT now I have a new problem.
Now if I am driving at highway speed and let off the gas it feels like it immediately down shifts for a few seconds then shifts back up and coasts along until I give it gas again. There is enough resistance that it feels like a jake brake or that the breaks are being applied. Also if driving along at 30 - 40 mph and just holding the gas in the same spot maintaining 30-40 it feels like it down shifts and up shifts over and over until I either give it more gas or let off all together. Also a few times pulling away from a stop I will get a thump.
I have an appointment with a transmission shop in a few days but today on the way home I put it in second gear while going up a hill so it would not shift and it seemed like it was coughing and sputtering. So now I am wondering if that is what is happening and either feeling like or causing the down shift up shift issue.
If it is a missfire issue why would the new torque converter cause this? It has all new motor craft plugs and all new after market coils.
There are no check engine or other warning lights lit on the dash. I have a cheap ODB scanner and it shows two codes. B1676 which apparently is a Battery Pack Voltage Out Of Range or ABS voltage issue. The voltage is showing at 14.2 volts and there is no noticeable battery issues. The second code is a P1000 Drive cycle test not complete. (this code has been showing for some time the 1676 code is new since the torque converter swap)
One side note: after the TC change every time I start the truck the radio/cd changer cycles though all the CDs. like it it is checking for a disk so it clicks and pops around from a moment. The only time I heard this happen before was after having the battery disconnected. The clock is not reset though like I would expect if it was losing all power.
Gonna change my oil in a hour or so and I was wondering what the torque spec is for the oil drain plug.
View 3 RepliesI am getting a little frustrated with a leak on my rear differential. The leak is on the front of differential rear-end just behind the four bolts you take off to remove the driveshaft. When you take the driveshaft out, there is a single bolt and the seal behind that is leaking. Here is my dilemma, I called my local ford dealership to find out what the torque rating on that bolt is so when I replace the seal I don't over-tighten. He told me there is no torque rating on it because I have to tighten, measure, tighten, measure the bolt. I was lost, I didn't have a clue what he was talking about.

View 1 Replies2006 F150, 4.6 V8 ... My truck was running fine until one morning I was sitting in the truck giving it my customary 30 second morning warm-up and it starting running very rough and quickly threw Check Engine LED.
I hooked up my laptop and got the following error codes: (To assist with future searches, the error codes are P0302, P0303, and P0353)
It seemed to drive fairly well, but low RPM torque causes major shuddering, so I try to keep the revs up to avoid damaging other components. The first step was to replace the spark plugs. They looked to be original and I'm at 140K on the truck, so it's probably time.
I went with Bosch Platinum as the factory plugs were platinum. When replacing the plugs, I moved the coil pack from cylinder 2 to cylinder 3 to determine if the problem would move. After the plug swap, the engine did run noticeably smoother (so the plugs worked overall), but still had the low rpm shudders and the same error codes (after clearing them).
Unfortunately, the error codes still indicate cylinder 2. I guess a misfire could be related to the fuel injector as well, not firing at the right time or not a complete spray, but what else could cause this?
I am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?
