Shook me sh*tless
 

Well on my way home today on interstate goin 85mph went over a bridge and truck just started shakin pretty bad so I slowed down and kept goin at 65. Decided to see if it would happen again at 85 so got up to it and over another bridge it just shook like hell for a good half mile or however long it took me to stop. Pulled off interstate got out looked here and there couldn't really see nothin out of the ordinary so got on my way home just did 65 rest of way and it was fine but I could still here some noise comin from under truck. Can anyone give me any insight what to look for? Possible driveline issue or suspension issue any help is greatly appreciated

DEATH WOBBLE

why would it only do it at 85 goin over bumps

Track bar and shimmy shock for sure.

Yep DEATH WOBBLE :scare2::scare2::scare2::scare2:

Check the tie rods and Ball joints while you're at it :c:

Because it upsets the suspension beyond what it's capable of dampening. Once you trigger the imbalance, the only way to get it under control is slow down until it goes away, hopefully before you find yourself careening into the woods at highway speed.

What do you mean by shimmy shock?

yep death wobble for sure. still chasing my death wobble down. re balancing my wheels helped mine a lot but still having problems. im assuming they mean the steering stabilizer shock also known as the steering damper when they say shimmy shock. mine is being replaced this week. track bar is a common culprit as well.

So there is really no for sure issue? Just got to throw money at it and hope it fixes it?

If it only happens at 85mph on bridges, then you don't have it nearly so bad as most. There are a number of inherent flaws in the steering geometry of these trucks, and any one of them could be the main culprit although all or none may contribute. Steering damper is common, the bigger your tires are the beefier it should be to compensate. The track bar is commonly bitched about, and upgrading is commonly praised as the solution. The steering box is mounted to a tin can, and a reinforcement is a well known fix. But depending on the condition of all of your front end components, it's hard to say from here.

it can be several things wore on the truck. jack the truck up and check everything. :hellox:

first thing i would do is with your truck on the ground have someone move the steering wheel back and forth and check for play in the joint were the track bar attaches to the frame. also check for play on your tie rod ends. make sure all are tight. also when is the last time you have checked your lug nuts? make sure they are all tight. you may also want to check the bolts on your control arms, they are prob tight but just make sure. also may want to re balance your tires and wheels. and also make sure your steering damper is not blown out. not sure if that covers everything but im sure someone will add if it doesnt.

So just got to hope get lucky with the first part I throw at it. I don't know if this would help in the diagnosis or not but durin the crazy ass shaking steering wheel was perfectly fine I had full control over steerin. Does this help anyone to give me any insight of what part could it be? Is it just something simple like trac bar or stabilizer or what? I don't want to throw hundreds of dollars into it especially since I'm buyin an old huntin truck this comin weekend

if you find something wore it needs replaced anyway.:hellox:

Agreed. Whether or not it makes your 14 year old truck do 85mph over bumps like a new Corvette, replacing worn parts can only protect you from some other catastrophic failure at the very least.

Nobody said to just throw money at it, nor can we diagnose it over the web, we're giving you the known common causes of your problem. You have to determine wich parts are worn. :c:

Just don't do 85mph in a dually!!:choochoo:

If you're unhappy about it characterizing the normally expected maintenance process of replacing worn out parts, then just drive it until it comes apart and get a new one. Hope you don't kill yourself and/or someone else in the process.

Otherwise, buck up and get the damn thing fixed. Chances are it needs alot of work. If you can't do it yourself get it into a shop and get it fixed. Pretty simple, really.

cody is a good guy. he was trying to fig a point to start at. after we told him it could be a combo of several things doing the death shake, he knows what he has to do. check the whole front end :hellox:

I'm sure it's one or more likely several things listed in this thread :c:

I had the same problem I put a steering stabilizer shock on it and wah lah no more worries bout bridges or pot holes

Ok. I recently started to rebuild the front end of my truck. First the steering box went out and the short end of the center/drag link was damaged during removal so that was replaced as well. (This was around August). In November I replaced the long end of the center/drag link(can't remember the brand), track bar(Moog), steering stabilizer shock(Monroe). Truck incurred a slight death wobble after completion when trying to stop. Took the truck in for alignment and was informed that the Rancho stabilizer shock I originally installed wasn't a wise choice. The wobble got worse after alignment, so I switched the shock to the Monroe. All seemed well afterwards, but the truck gradually developed the wobble again and its gotten progressively worse. It only occurs when I am trying to stop the truck and I have temporarily parked the truck because it is that bad.

I am writing a list now and am curious if you guys have any recommendations. So far I have tie-rods, front shocks, stabilizer bar links, and stabilizer bar bushings. Front brakes are new and the bearings are good. Keep in mind that I am keeping close watch on my budget.

Also, had a guy get underneath and he noticed a very slight bind in the track bar at the frame. I took the old one to the auto parts and verified that everything matched up. The bolt can't be tightened anymore either. Would this have anything to do with the wobble?

Sorry to piggy back this thread but I thought it might have useful info for the OP. Thanks!

Huh... everything about how mine rode and handled improved with the Rancho stabilizer. Interesting.

Anyway: steering box stabilizer.

also check your control arm bolts. they can also cause trouble for you. they are probably already tight but tighten them up the best you can anyhow.

I'd like to say thanks for all the info everyone has givin me that's been useful. Hopin to get a chance take a look at it this weekend if weather cooperates.
As for nadirpoint I was lookin for helpful information as of to whether or not someone could me give me a for sure answer as of to what the problem is if possible cuz I ain't got money flyin out my ass for a whole new front end rebuild, wasn't lookin for some assholes smart remark

Don't worry about getting any more suggestions from me then! At least I'm not stupid enough to think somebody can diagnose my death wobble and give me an easy, cheap fix over the Internet.

Asshole.

I ain't worried bout gettin any advice from you. I did better without it :tu:
And I've experienced the death wobble so yea I'm goin to seekin some straight forward diagnosis

Is that why you kept cryin' about throwing money at it taking chances on replacing a part without proper diagnosis? :w2:
