Annoying vibration at high speed

[GeorgeRaye]

Hey,

Have a 2003 Sahara 4.0 5 speed manual.

Just had the clutch redone and now I have a significant vibration when going around 80+km/hr. Mechanic that did the clutch has taken the drive shaft off and changed out the u-joints with no luck. Tires have been rotated and balance tested. Vibration is strong and shakes from the center and makes the rear view mirror shake too. Almost feels like the shake you get when accelerating in too high of a gear for the speed.

Thoughts and suggestions greatly appreciated!

He probably didn't mark the u-joint to yoke timing on the driveshaft ends and installed 180 degrees out.

He probably didn't mark the u-joint to yoke timing on the driveshaft ends and installed 180 degrees out. Then replaced u-joints chasing a problem he created to start with.
Try changing orientation 180 at pinion yoke and test drive.

I will give that a try, thanks!

You can pull the rear driveline and test drive in 4hi and if that doesn't eliminate the vibration pull the front driveline and drive in 2wd.
