After I lifted my 2006 Jeep Cherokee KJ Diesel (4.5cm in front 5.5cm at rear).
I started getting some vibration under heavy acceleration at around 80km/h.
Vibration is only on heavy acceleration and not on deceleration. Soon as I let off the acceleration the vibration goes away. If I accelerate gently the vibration doesn't occur.
I have already ordered the rear Ujoints (Moog greasable), but a few weeks away.
Checked front CV by driving in circles and listening to a clicking sound, but I didn't hear anything.
I heard some have had to drop the transfere case a bit to fix the angle of the driveshaft after a lift.
I took the Jeep to a driveline specialist, and they advised me I should give the springs to settle for a few month (suspension done 3 weeks ago).
They said they could try and put in longer shaft, but wasn't guaranteed to fix the issue and would cost around $400.
I also recently serviced (Auto Tranny fluid change and filters) the Auto tranny, and used 2 x Dr SHudder Fix, as well as the Transgo kit.
I don't think it's the tranny shuddering as the issue was not there before the lift.
Anyone else had driveline vibration after a minor lift (heavy duty spring) ?
Is there any diagnostic I can do myself at home to try and find the cause ?
Could it be worn rear lower control arm bushing and under heavy acceleration it allows too much movement ?
ps.
My money is on the Ujoint, as I am experiencing the exact same issue as below (it's on a TJ though)
