2000 Silverado Vibration
 

Would an out-of-balance driveshaft cause shudder/vibration at different speeds?
Starts about 40 to 50mph, calms down, then again at around 60 on up. I don't even want to take her over 70. I can slap it into neutral and the slight shudder continues. Tires were balanced, which eliminated some of the vibrations the old girl had, but mech' feels the rest may be the driveshaft.

Thoughts?
Thanks,

I had a broken steel belt in a tire that caused some ****ed up vibrations once

came for the sex jokes. stayed for the silverado.

Let wife drive and enjoy it.

This sounds like the steering damper. Had this happen in a chevy 1500 spare work truck around that model year.

Yep! I had a 2001 Silverado and experienced the same thing. My good buddy out here has been working on Chevy trucks for over 20 years said that was my issue. Definitely look into it to be sure.

man like you driving a twenty year old truck to go fishing ain’t right. After a career jackin hogs you need to update that silverado

Wrong Hog ROFL This one "rides em" not "jerks em"

Damn what a no reading sob , better get new glasses

:LOL: Dumbasssssssss!

Lol no shit but then I ain’t in the hog business or smelling hogshit. I prefer wading in cowshit it doesn’t linger near as long.

Should have bought that Unicorn Yukon when you had the chance.

careful choosing which mushrooms to pick:evil:

It’s me with your wife in the back seat.

Sorry, brah.

If it’s a driveshaft, typically You can grab it and shake it and feel the slack in the u-joints. If its that, get it fixed right ****ing now. A driveline coming apart and ripping everything under there clear to hell is catastrophic.

I presume it is in 2wd? We had a 99 that had a bunch of trouble with the transfer case.

Check and make sure there isn’t a chunk of mud in the tires first. Even if you just splashed through a puddle it can be enough to **** up your ride.

Steering Damper was part of my 2015 Silverado vibration at 55-75, balanced also...helped but still there

RWD regular cab. This happens on newly paved perfectly smooth roads. Odd for Illinois I know, but if there are no irregularities to dampen, why would the sucker shudder Due to a bad damper? U-joints are firm, but I really don’t want to put the sucker up on stands and run her up in rpm with a piece of chalk taped near the shaft to check for balance issues. I’ll look into the steering damper, but seems odd it would occur on smooth roads and always the same road speed.
Thanks to y’all

Rotate tires, check your driveshaft u-joints, lift the front end and check your ball joints, check the steering damper.

Ball joints new
u-joints tight
Tires fine, rotated regularly and balanced
vibrates even when coasting at said speeds

Now I'm not a truck guru so bear with me: I look at auto parts stores for steering dampers/stabilizers for replacement and they only show up FOR 4WD!

My inference is they are only put on four wheel drive and that takes it out of the solution category and some of y'all are and idiots.

or

You can no longer buy steering dampers for 2000 Silverado RWD trucks.

OR - one of our fine CP members can provide a link to purchase a RWD damper/stabilizer which y'all say is the freaking problem, as auto zone, advance, napa, and o freakin reilly don't show any for 2WD. (or I am blind and can't see one listed)

thanks for your patience,

People who need and use trucks buy 4x4s. They get you stuck better so that short of a D9 or track hoe can pull you out.

Also, you didn't specify what your truck was so you got many opinions. I will bow out as there is a multitude of possibilities. Maybe Sauto will chime in as this sounds like a problem he could give you a few things to narrow it down.

I will also add since I'm a prick a quick peek under your trucks front end will tell you if a steering damper is there.

If you're absolutely positive it isn't the tires then yea, I suppose it could be the drive shaft. But those things don't just go out of balance, or throw a weight. If you can, put the rear end on jack stands to get the tires off the ground and put the transmission in neutral then crawl under it and spin the drive shaft slowly by hand. What you're looking for is a dent anywhere along it indicating it's been hit by something and bent. It doesn't take much, the tubes used to build drive shafts have surprising thin walls.

What was her name?

You're not really "stuck" until you have to call in the Skycrane.

have them check your driveshaft, mine was cracked.

and to the OP...


does the vibration change on or off the throttle?


at this point i'd start by taking the driveshaft out and making sure the u joints are free. they rust internally on those and try to lock up and then cause a vibration.

ive seen some REALLY ****ed up driveshafts that never caused any vibration lol.


like stuck in the creek, high centered on it and leaving a spiral dent all the way down it ****ed up and no vibration lol
