Heys Guys Thanks for reading,, I have a 95 Pete exhd this truck has a terrible vibration somewhere in the rear..This is what i have done,,,New drives, had all u jolints replaced, also had driveline balanced, new carrier bearing, the ride height has been checked, Also had wheels centered on studs,,,I had new shims, shackles and spring hangers put on front, with new steer tires, cuz originally i thought it was on the front....Trying to make this short....I feel the vibration in my butt and feet. When you load the truck it settles the vibration a little until you get up to about 72 mph....Thanks for reading Butch Mosley

Did you have both drivelines checked? Does vibration go away if you put it in nuetral ? Does vibration change when you accelerate or let off?

I'm guessing it does it loaded and empty?? I would have to agree with the earlier post,that it's likely in the power divider, It still may be the ride height too. Just one of the many reasons I like Kenworth better than Pete. Good luck!!

check the balance of your brake drums! An easy way to do this is to jack all tires off the ground substantially, tighten all brakes down except one and run the truck through the gears, continue this with all four corners until you find the guilty one! be VERY careful with this procedure and have someone around who KNOWS whats going on.better yet, ask an OLD TIMER to help you out. This is OLD SCHOOL truck diagnostics!!! REPLY REPLY WITH QUOTE

Your ride height could be correct, but you could have a levelling valve that is not working right. I tend to agree more though that it's still in the driveline somewhere. Bearing in the back of the tranny or yoke on the rear ends. You checked to make sure your drivelines are true and in time? Wrong ride height can sure cause it though. REPLY REPLY WITH QUOTE

If you haven't figured out the problem yet it could be the cluth or the flywheel bolts loose or some broke. I've seen both cause the same kind of vibration and they were hell to find cause that's usually the last place everybody looks when there is a vibration in the rear. REPLY REPLY WITH QUOTE

Might even be a shock gone bad. I drive a 00 Int Eagle and had a right rear drive shock go bad and we spent forever and a day trying to find it. Just a thought

Does it vibrate bob tailing or pulling a trailer? Could be in trailer tires or trailer alignment. Check shocks on truck and trailer. Could be loose or bad wheel bearings on truck or trailer. Check to see if tires are balanced. This is a cheap way of adding miles to your tires also. REPLY REPLY WITH QUOTE

Sounds like your vibration is coming from trailor. I had truck with same problem and after doing everything like you have I switched trailors and I had no vibration at all.

Butch,
I saw a W900 one time that over time had "wallered out" the holes in rims where lug bolts go through. This case was on steer tires, but caused awful vibration. Fix was very simple....spacers of some sort were eventually put on the lug bolts and problem was solved. The rims were shifting just the slightest bit on the lugs as they went around.
