Okay i lowered the transfercase crossmember to line up directly to the diff pinion. Same angle, Test drove it and the vibration is still there.
Rotated the wheels to eliminate the tyres already. I do have some new 33" tyres i could swap thou.
Engine mounts are new. I will check the shocks, seem ok when you bounce them.
The transfercase has some movement so i guess i will strip the back off and check where the movement is coming from.
The movement seems to be the rear roller bearing, which i read is normal to have some movement?
Transfers where all rebuilt with new bearings when the dual cases went in. Is it possible that the rear bearing could be of poor quality or the clearances not as good?
