Peterbilt 389 Shakes So Bad It Will Take Your Virginity.

If it isn’t transferring directly to the steering wheel it is probably not the front end. I would crawl under and make sure your drive shaft didn’t pick up any rags, cats, or hobos. Then I would check the drive tires looking for one with odd wear patterns. If you have a laser temp gauge and the offending problem is a tire it should get hotter than the others. I hope you find the issue, it sucks to rattle all day.

 

i checked and the only hobos i found were in the cab...
on another note, the tires are all wearing even. all 10. tried the temp guage, all tires are similar temps other than the innermost on all four rear axles. even temped all the shocked and the lowest i got was 116F and that was bobtail

 

Sounds to me like you might have a busted inside wheel on your drive axle. Sometimes it's hard to spot. An aluminum won't shatter like a steel wheel.

 

Call the king of truck ride problems. MD Alignment. He has radio show on satellite radio every Thursday I believe. He has a guy in Kansas City that really good.

the truck has had 10 brand new aluminum wheels put on it and all 10 balanced with zero change

 

is there a direct line for them? i got free satellite radio from JB Hunt for hauling X amount of loads with them but never activated it

 

Driver, is it a low or high frequency vibration? In other words, is it slow or fast? If it's a fast vibration, have a driveshaft shop balance the shafts, or if you're a do-it-yourselfer pull a front and rear axle shaft and spin the driveshaft and start pulling sections, rear to front. Only 1 thing on a truck creates a high frequency vibration...the thing that's spinning really fast.

 

I'm not sure we can post phone numbers on here or not. If you click on the blue lick that bring up his Facebook page and he has link you call call him. That's the guy in Kansas City that has a shop. He would probably talk to you they say he is very good. Basically he won't let you leave his shop till the truck is fixed they way you want it fixed. You can call MD alignment but the guy Mike Beckett is retired from doing the actual alignment. He been doing them for like 35+ years. His son is doing the alignment now. Mike sell his system to do alignment. So he till know what he talking about. He will tell you those laser alignment system at truck stops are no good. Because just like your truck nobody can find anything wrong. Call Chad in Kansas City Alignment solutions. They check everything. Maybe put your truck on a Dyno and run it and see what going on

 

Driveshaft Runout.

 

Rebalance won't fix a runout shake.... I went through this exact same thing with my 389 ...
