I currently have 2 LTL9000 trucks and they both bounce and shake hard from 35mph to 45 mph, almost violent shaking. I talked to other LTL9000 owners and they said theirs did the same thing...just have to learn to live with it... has anyone ever found the problem that causes this? No its not the tires or kingpins or bearings...all have been replaced in trying to find the issue.


I love my trucks but i can barely stand to drive mine, and other drivers dont want to either because they are so rough in the lower speeds.

 

Back in 1987, I started driving for a company that had year 1985 LTL company trucks. I slip seated from truck to truck and can't remember any vibrations at those speeds. They were very plain trucks, had Dayton (wagon wheels) and tiny sleepers. Very heavy trucks, but they took the pounding of northern Canadian highways. The company only kept trucks for 3 years, so maybe the vibration comes with old age. Other than telling you when new they didn't have the vibration, I can't help you otherwise.
