Ford - F100 :: 1976 - Wobble Randomly Appear At Speeds Over 45 Mph Or After Hitting Speed Bump Or Cattle Guard
Feb 16, 2015
So I have 1976 f100. For the last few months I have been dealing with the famous death wobble of solid axle trucks. It seems to randomly appear at speeds over 45mph or after hitting a speed bump or cattle guard. I have tried several things like replace all the bushings in the front. Ive looked for any bars with play and fixed them right away. And I even replaced the ball joints thinking it would work. I actually let another mechanic to solve the problem, I was fine for about 3 days. I am running out of parts to check and its hard to drive it down the road.

I purchased the truck from a used car lot about 3 months ago and after driving for a few thousand miles I am feeling a slight wobble after hitting a bump in the road. Here is my truck set up:
- 2011 Ford Lariat F250 4X4 FX4 6.7 ltr
- 67400 miles
- Tires stock and great tread
- Rancho steering stabilizer kit
- Rancho Shocks
- Rear air bags
It does appear one of the rancho stabilizer dampers is leaking slightly. Why would the previous owner install a rancho stabilizer kit? Is it because of the rear air bags?

I have a 1976 Ford F100 with a 302 and my problem is sometimes when my engine is running and I try to cut it off, it continues to run and the only way to stop it is to jerk the coil wire off. This is an intermittent problem. Happens about every 6 or 7 times I drive it. I have replaced the ignition switch and still have the same problem. Pretty sure it is some type wiring or ground issue, just need someplace to start.

My car has developed a strange squeak from the front suspension when going over large bumps or speed bumps. Most of the time it only happens when i hit a speed bump with both tires hitting at the same time. It is a slow squeak not very high pitched but shouldn't be happening on a car with stock suspension components and less than 12,000 miles.
Why my car would be doing this, under normal driving conditions i don't hear any sounds. Its just when i go over speed bumps and large bumps on the road. It is also only from the front suspension.

2012 SE with 4 cylinder 35K miles. When the front wheels go over a speed bump at a couple of miles per hour I get a noise which sounds like something hitting the floor board of the car. It is a loud single thud. Much deeper and louder than a loose seat would make.

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.

OK, a couple of days ago I hit a good size bump and got the dreaded death wobble. I stopped to check the lug nuts and none were loose... jacked up one side at a time, tried shaking the tires to see if anything was loose and to my surprise on the drivers side I could move the tire back and forth (like turning the steering wheel, not around) so I figured something had broken right as I stopped. Is it supposed to do that?? I know it`s not on older vehicles.
Anyway I figured I was stranded so I thought what the heck, I`m gonna see if it will turn with the steering wheel. Well when I did... with drivers side still off the ground it gets the death wobble, oh it was running when I did it. I jacked it back down and it stopped so then I tried turning the steering wheel to see if it would turn and both tires turned as they should. I was scared to try it but I drove on home about 4 miles slowly.
My brother has an older Saturn and his wife was driving it and from the way he described it, it got the death wobble. Someone told him it was the serpentine belt. He changed it and it didn't happen anymore. Does it sound possible that the belt could be my problem. BTW, the truck is a 99 ranger 4x4 with no lift or anything.

I have an 09 F350 (116,000 miles) that I have only owned for about 3 months. I got it pretty cheap but it did have a front end issue. Drives fine most of the time but hit a bump just wrong at highway speed and it goes into a shake and wobble that feels like you just blew a front tire. Took it into my shop, not the dealer and was told I pretty much need a front end rebuild. Kinda what I figured I would hear.

Got the death wobble, had everything replaced. Wobble was worse, upgraded track bar. Then no wobble but bad bump steer. Put on new OEM track bar.
Ok but still if I hit a hole on the interstate I get death wobble and little mini wobbles on any bump. What is the permanent fix for this other than selling the truck?
2011 6.7L FWD Lariat, upgraded exhaust and Def removed.

I just had vehicle inspected and replaced the wheel hub assemblies on the front Left and Right wheels in order to pass. Now while driving strong shaking occurs occasionally when over 60+ mph or at any time after a hit a bump in the road. have to slow down below 30 for it to stop.

I have noticed a serious bump steer or a violent jerking action when hitting a bump in the road. Just over a year ago I replaced ball joints,tie rods, sway bar links (2nd set since cutting off original). I used MOOG components. I was shocked to see the sway bar links loose once again. Is there a certain way to tighten them or is there a better product available. Mostly stock 1999 'ploder with fire wires and scremin demon coil pack.

This rattle noise occurs when hitting just about any kind of bump. Sounds like coming from driver side. It sounds like something loose like a washer rattling against something metal. I recently have replaced the radius arm bushings, front springs, and shocks. The sway bar links and bushings look and feel ok. What it ended up being? I have never heard ball joints make such a noise but it wouldn't surprise me if they were in need of replacement.

What would cause me to lose accelerator pedal function after hitting a bump? The engine remains on, the CEL comes on and after a few seconds or shifting into neutral and back into drive I regain the accelerator again and the CEL goes out
The truck shows no codes. It is if some connection makes/breaks intermittently when I hit a rough pavement. Also, she sometimes won't shift in reverse. Could it be related?

About 4-5 weeks ago my 2002 F-250 7.3 just died with no warning after coming off the highway and since then it hesitates/dies when hitting a bump or while applying pedal with the A/C on. The code that keeps popping up is the P0344 "CPS" and the code for back pressure sensor... I have replaced the CPS twice "making sure the 1st one was not bad", the back pressure sensor and the tube the goes the manifold, and fuel filter and still having problems... I didn't know if there could be a fuel pump issue or something else?

In the last two weeks I keep getting a squeaki-ish ratter from the back whenever I hit even the slightest bump.
Dealer will look into it next week? I think it has to do with the rear seats.

I hit a bump while pressing the brakes for a stop sign (going down hill), and I hear/feel this grinding noise through the pedal right when I hit the bump. I assume it might be the surface after the bump as it happened in the rain and it could be slippery causing the brakes to lock or something. I don't know, I might just be paranoid.

Everytime I hit the slightest bump I here knocking, tapping or clunking coming from my front suspension what could it be.

Driving home the other day I crossed some railroad tracks. They weren't too bad, but bumpy. I wasn't going too fast over them, had slowed a bit with traffic. As I cleared the tracks and hit the gas, nothing happened. The car hadn't stalled and I didn't hear any noises, but for about a second as I pressed the gas, it didn't go in gear.
I think the engine revved, like it was in neutral. I looked down and the traction control light was blinking, but no clicking noises were heard. After a second it started acting normal again, and I have gone over those tracks again the next day to try to replicate and it didn't happen again. Is this a known issue, traction control kicks in when a bump is hit...but no clicking noise like i usually get on ice/snow? Or should I have it looked at?

My 2010 Camry was great the first two winters. Now after the windshield was replaced this summer, the dash rattles against the windshield when it is below 45 degrees and hitting a bump. The same rattle is heard from one A pillar too. Is this related to the windshield replacement or the age of the Camry? It would to determine if I should get another windshield replacement or wedge foam for rattle abatement.

I have a 70,000 mile touring SE which at low speeds( less than 20) has a rattling/clunking noise when hitting any small bump. Can not hear anything at higher speeds. Steers well noise could be coming from both sides. They did replace my transmission at 40,000 miles. Car does not bounce when pushing on it like a strut is bad.
