I just acquired a 1989 Jeep Wrangler wth ~157K. It looks like most of the vehicle is stock with the exception of a lift (~2 - 3 inches) and the 31" tires.
The shaft to the front differential is gone and the previous owner said the gears sounded kind of 'crunchy'. Unless I am eating Rice Crispies, I'm guessing 'crunchy' is not a good thing in differential...
It seems to run well, with the exception of a little inconsistent whining. Or maybe it is consistent and I just can't hear it as I am accelerating.
Any suggestions on where I should start with the diff? New innards, new axle?
Thanks for enlightening me with your knowledge.
