my HZJ 75 (1999) recently started to develop vibration in the chassis. In the beginning it started to be noticeable at 100 km/h and it would be less at 120 km/h. Now it is getting worse (louder) and driving faster than 100 km/h is a real nuisance due to the noise levels.
I had all wheels balanced and revised the right front swivel hub and wheel bearings, as the grease was leaking. The bearings (kingpin and wheel) were well past it. Anyway, it did not make a difference. The left hand side swivel hub is on the to-do list but no grease leaking there.
Other symptoms: the chassis only vibrates on a positive or neutral throttle. No vibration when the engine is driving the car (engine braking). If I drop the clutch on a positive throttle, the vibration continues. If I am engine breaking and drop the clutch at the same speed, no vibration. I would conclude therefore it must be coming from the drivetrain. I checked the forum here but no real clues other than play in the UJs (have not checked that yet).
Anybody any suggestions on how to analyze this?
thanks
Steve
