I've recently installed a 3.70 R200 clutch-type LSD into my Z, and just need a sanity-check on limited slip diffs. When turning the driveshaft by hand with the car on stands I noticed that both wheels turn in the same direction (as they should), but the drivers side turns at a faster rate than the passenger side. I'm guessing that more rolling resistance on the passenger side is causing it to slip more, am I correct in thinking this? The brakes aren't dragging, and the company I purchased the diff from checked the clutch adjustment and backlash.
I'm chasing down a rear diff clunk that I believe is a bad driveshaft u-joint, and I noticed the aforementioned when checking everything. I've got new diff mounts/straps in place, and all the bolts are buttoned-up nice and tight so it's new u-joints for the halfshafts/driveshaft next.
