I had been running 8 contacts faces for 40k miles and was releaved to find very very minimal wear to the disks. I did want to go significantly softer so I restacked it with 5 friction faces and removed the spacer shim(I only had one). I left all 24 friction plates in. I do wish someone had a suggestion on bolting the lsd case back together with less frustration. Getting the two halves together without pinching one of the little clutch plate ears is a struggle.

I also found that my stub axle seals had a bit of wear and the lip was getting thin (214k miles) So I went ahead and put new seals in. I should have it back in in the next week or so and will update on how it feels.

I now have zero chirping even at slow parking lot speeds. Still spins both tires equally through 3rd right now. I will have to wait for some actual track time to comment on track behavior.
