    What do our cars Have? Im thinking we have limited slip, meaning one wheel pulls. Is there a way to make both of them pull evenly or would this be a bad thing?

    I'm almost positive we have limited slips, hence the 3L27 stamped on my differential. :dunno:

    WyoTechMSA, Made a post call "some bridge i own" where he does a massive burnout and it looks like both his wheels are spinning as he slides away. The passenger rear wheel spins more on my car.

    I think that all the diff's are limited slip/posi (7.5 and 8.8) , but over time the clutches in the diff get wornen out and only one wheel spins. That's why you use the Friction Modifier when you change your rear-end fluid or use Royal Purple.

    I ya want to get rid of that, get a new diff (a locker or a new limited slip). When I do my rear 31 spline strange, 4.10's and the FRPP diff used in the terminators

    a buddy of mine put my gear in for me a couple of years ago,he said you can use different thickness shims when installing the differential,using the thickest ones will put more pre-load on the clutch packs effectively "locking" the axles all the time...thats what he did to mine and ive never had the one-wheel-peel problem....

    When the traction Lock is working properly, both wheels will constantly pull in a straight line, but when going around a turn the inside tire will slip so the car does not skip around the turn. The traction Lock rear has clutch pacs in the carrier that allows this to happen. When the clutches wear out, It will act like an open rear where only one drive tire puts power to the pavement.

    On the old 9 inch rears you had to be careful when changing clutch pacs in the traction Lock rears. People would add "extra" clutches to constantly lock the rear, and cause the carrier housing to crack after hard use. I had this happen to me.

    A Detroit Locker is a constant locking rear. It uses gears instead of clutches. When you make a turn the inside tire will skip from losing traction. They are virtually indestructible.

    It's not IRS, it's just the differential
