I just bought a stock 1999 XJ, never been off road or abused, never towed anything, 97K mileage...all u-joints, engine/transmission mounts, leaf springs, etc. seem good, idles about 775 rpm...and yet it clunks and lurches when put into any FORWARD gear, but NOT AT ALL WHEN PUT INTO REVERSE.
Has anyone else ever experienced this ASYMMETRICAL clunk/lurching on their XJ?
The only thing in the drivetrain that I can think of that would be affected differently going in the forward direction as opposed to the reverse direction would be the transmission itself...but the noise seems to be coming more from the rear end.
Is there something about the way a differential is built that would cause it to clunk in the forward direction but not in the reverse direction?
