Its amazing some times how we over look the obvious.First off I lifted it 3in and installed 31x10.5s when this started.
For the last week I have tore the rear drive shaft apart 3 times.
I replaced the u joints and the noise was still there.
Clicking loud at times when making a right turn or accelerating
I installed new ujoints then took them apart again i could not get rid of the noises.
Finley today while talking to a Friend he saw that my xj was leaning to the drivers side.He got the tape out and shure enough it was 3/4 in lower on the drivers side .Panic for a minute measure every thing could not find the 3/4in.Then i check the tires."Tada".
the front 27lbs each OK the passenger side rear 21 driver side 7lbs there it is I air them up and got my3/4in and the CLICK iv been chasing for days is gone. It was the dam LSD.IT mimicked a bad ujoint to the"T".
so I felt so stupid i had to post this just remember to cover your BASICs when diagnosing a problem.
