Ford 6.7L Power Stroke Diesel :: Death Wobble Still Present After New Shocks And Steering Stabilizer
Sep 4, 2012
Recently replaced the steering stabilizer with Rancho RS5415 and all 4 shocks with the adjustable Rancho 9000XL. The death wobble at 40-60 mph on rough roads has not gone away. The truck rides much better, however the death wobble is violent enough to shake the change out of the change holder and the only way to stop it is to pull over and slow to 10-15 mph. The steering wheel also has slight vibration when going over smaller bumps such as expansion joints.
2011 KR 6.7L 4x4
47k miles (no ESP)
20" wheels with stock size tires
100% stock no lift or modifications
Never wrecked & most driving is on the highway. The tires show no signs of abnormal wear and the truck drives straight.

I have a '15 Ford F-350 w/ 6.7 - 34k miles. Most of my driving is towing a 30'RV trailer. Today, without any trailer, I was on a local interstate and at around 65 mph on a bumpy stretch of highway the death wobble started. Had it come and go 3 times in a few miles requiring me to slow to about 45 or so to stop it. Never had any such happening prior.

Trying to replace my steering stabilizer and in the process I broke the nut close to the steering box. Would not budge so used a bar and well I broke it. Now I can't pop it out am I doing something wrong? Here are a few pics. I'm totally bummed nothing seems to be working for me.

Is this part covered by my premium care esp warranty? I thought that I read it was at one time might be mistaken.

I'm looking to replace the worn out skyjacker or rancho steering stabilizers on the ex. Wanting to put bilsteins in there place. 5100 series to match the shocks for the truck. What are the part numbers for this setup?

My wife's having trouble with her '02 Explorer 4x4 V8 XLT.
Today I experienced a violent steering wheel shudder that I would describe as the old "death wobble" you hear about on solid axle trucks, Early Broncos, Jeeps, etc.
At 55mph, in a slight right hand turn, a little bit of a bump in the road triggered it. I held on to it as the steering wheel was rotating left and right a few degrees (maybe ~10deg) and it wouldn't stop until I slowed down to around 35mph.
I crawled underneath and didn't see anything obviously bad (tie rod ends, ball joints, etc).
Then I noticed when turning the steering wheel (with the engine running, but parked) I could feel it shuddering slightly as I turned it.
The PS pump makes quite a bit of noise so I wonder if its on the way out.

My old truck is still running, running pretty good actually. it has a "tick" though. it is only present at low rpm while driving. it reminds me of an exhaust leak or a lifter on a gas car. I looked under the truck where the exhaust stuff hooks up and didn't notice any soot evidence. it doesn't make the sound in neutral as bad.
I did the buzz test with forscan and they all passed none sounded weak. I did the CCT test and 3,8, and 5 failed. I am running the grey CPS and have read it can contribute to a fail on 3 and 8, don't know about 5. If it were a rod knocking, I am sure I could tell, that's a fairly distinct sound. I am wondering if the bearing on number 5 rod is getting bad? truck doesn't burn oil, only a dab of black smoke when I really spool. it will make the sound also on deceleration.
I plan on replacing the engine soon, but want to salvage the core so I can tear it apart and learn maybe build a go getter.

I put on a leveling kit a few months ago and pretty much replaced a lot of worn out parts in the front fenders. With the exception of lower control arms, shocks and springs. Just about everything else that moved was replaced I think.
Well now it seems like every time I hit a decent bump in the road my truck jumps to the side. It's very noticeable if I'm going around a corner and hit a bump. The steering wheel is thrown from side to side so I'm fairly certain that the issue is up front but don't really know where to start looking.
The truck may have done this before the leveling kit but it's very exaggerated now. It's so bad at times that my husband won't drive it.

It seems that my 2010 F250 truck has come down with the dreaded death wobble. My truck is stock and has 63k miles. I was driving home today on a 2 lane side road and hit a few bumps that almost put me into the oncoming traffic. That sure did get my attention! I've been ready a lot on this site and wanted some opinions if replacing the stock steering stabilizer would fix my problem.

1999 F-350 7.3 Dually 2wd Front End issues. I think I may have several things going on so here goes. Truck has about 130,000 miles on it . Bought it with 60,000 miles in 2009.
It's always worn the front tires weird but it's gotten a lot worse and it's happening in about 10-15 thousand miles now. It's wearing the tires on both sidewalls like under-inflation but I run 70 lbs in them. I've noticed for several years now that it makes a knocking sound and I feel it in the floorboard, shakes in the steering wheel when I turn to the left only in a corner at speed. (65-70) ...
Now it's started intermittently going into the death wobble at slow speeds like the caster is to negative on it. I'm sure it could use some shocks but I just rotated the tires and I felt no play anywhere. I know when we used to get that bumping in the floor board on older Fords it was a bad radius arm bushing but that couldn't be all of what's going on here. I've done searches on this and it has happened to others but I haven't found a resolution from any yet.

My 05 F20 CC LB 6.0 4WD has the alternator light on for a few miles then goes out also sometimes goes away when you accelerate hard, is my alternator going, or is this some common glitch in the light hopefully?? Also every once in a while got the death wobble, installed tie rod ends and center link, but if I hit a bump just right it does it.

So this '06 F350 is blowing fluid from the steering pump fitting when you move steering wheel to either side all the way(lock). Is the internal o-ring blown in the fitting? Do these have the teflon seal at the pump? Pretty new to the 6.0 scene. Got a new line ordered.

When replacing the power steering pump on my 2006 should I go OEM on the pump or save some money and get a Napa or aftermarket remaned unit with the pulley installed? Also, whar is the fluid capacity of the power steering system?

After my recent cooling system upgrade and power steering pump/HP hose replacement I am still hearing and feeling the power steering whine. I flushed the fluid and used Mercon V ATF fluid. I jacked the front end up with tires off the ground and cycled the steering lock to lock 100 times or more now and the whine does not stop. Do I need to put a vacuum on the system and try to purge it that way? There was no whine before but I just replaced the pump while I had room with everything out of the way and replaced the high pressure line because the fitting was leaking at the pump. This is very irritating because I thought replacing the pump would be beneficial.

I am having a heck of a time finding this coolant leak. It drips off the power steering pump. I replaced the upper radiator hose and the heater "y" hose that goes to the bottom of the Degas bottle. I recently replaced the lower radiator hose as well. So the truck runs normal. When the system is under pressure I do not see any leaks. But after the engine is completely cold it starts leaking a small puddle of coolant. Its appears to be coming from the power steering pump. But I am sure its something above or near it. This is on my 2005 Excursion with a 6.0. Can the water pump be going bad and leaking this direction. I would expect a water pump to leak straight down the middle of the engine. What to look for? The thermostat seal stays dry. but it has to be in that area. What is really messing with me is. When it is hot and pressured up It does not seem to leak. Only after it has been sitting for hours and cools off..........What the heck!

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

Okay, so i was driving down the road. Turned around and all of sudden I have no power steering... The fluid is good and I actually just replaced this ps pump 2 months ago.. Also when I hit the brakes they kinda feel weird too like there not working fully or something... Should I just start tearing this ps pump off?

I just wanted to share with you all a cautionary tale about belt tensioners and idler pulleys. I am now a firm believer in installing the aforementioned items when you replace your drive belt. 15000 miles ago I replaced the drive belt and didn't heed the warning of some here on the forum.
For the last month or two I have noticed what sounded like road noise which I dismissed because I had just had new tires installed that had a more aggressive tread pattern than my previous tires, I also noted that the ECT had been a bit higher than normal, like running in the high 190's to low 200's on average.
Well while driving today I get the alternator warning light and lose power steering and soon after the brakes got stiff, this was followed by ever increasing ECT which got to 242* before I could get it off the road and shut down. It is too early to tell if the noises and the ECT temp rise were the result of this tensioner going out...
For what its worth the only tools required were a 10MM end wrench and a bit of skin to get the job done.

Is there one thing that when broken makes both the steering and brakes lose all power? Does the power steering and hydroboost share a pressure source?
My brake pedal is dead and I get no steering boost, but the master cylinder and PSP are full of fluid. Do I replace both, or replace one first to see if that fixes both? Or could it just be a hose leaking? Not sure how to diagnose this one.

2007 F350... I noticed I have a small power steering leak where the master cylinder bolts onto the hydroboost. Is there a o-ring or seal between the two? or do I have to replace the hydroboost? Been looking online for a schematic but can't seem to find one.
