I'm saying my spedo is spot on now. As for strange noises, when I installed this rear end back in August (or so) it made such a horrible racket that I thought it was going to blow up at any second. I drove it a total of 5 miles. It was all kinds of bad. Now, it sounds like it should. Its definetly not as agressive as the H190 I have in my Datsun (that could very well be a detroit locker). All I know is that it pulls out of a corner now instead of just spinning a wheel, and feels more sure footed just going down the road. I like the taller gearing, the whole car seems happier. I still can't wait to run it though the cones on the 22nd.

disks vs gripper aka alfalholics

looking at redoing my 101 spider racer's rear end
currently a 5.38 welded setup
I have a gripper from alfaholics in my 67 gtv and am considering a lsd rebuild
after reading, it looks fairly straightforward
question is how it compares to the gripper style besides sheer cost
i see the gripper can go out to a 75% lock vs the 40-45 on the disk setup

any thoughts?

Welded diffs

Welding the spider gears are the primary cause of twisted and broken axle shafts particularly small 750/101/105 shafts.
LSDs allow internal slippage to keep shafts sound and drivability far less loose as wheels can operate at different speeds cornering.

The aftermarket diffs are not only expensive, but the lock rate you mention is useless even racing.

Parts for rebuilding the modified 2 liter LSDs to fit in 101/105 housings are everywhere when and if they begin to wear.
The Axle shafts also have to be modified so they fit with the RjR LSD units. (Resplined to larger diameter. But they still fit in the smaller 101/105 axles housings.)

The only setup is the bearing preload and lash. Simple.

The parts in these lower photos look to be extremely worn. Is this from extreme use, or normal driving with a lot of miles?

Damaged parts

In the first post the damaged parts in the last pic are from abusive use, not just wear.
