Did you lubricate all plates/discs during assembly? You NEED to completely cover them in 90PA (or your desired rear diff. oil).

Also, from your PM:

Here are my numbers: A=88.37 B=2.5 C=.5 D=65.7 E=1.5 F=86.37
E = 1.85 mm (always); this is the thickness of the bellevelle washers included in the kit (part no. 5). Because you used a value of 1.5, you over-compensated on the stack height causing extremely high break-away torque.

You didn't reuse the old 1.5 mm bellevelle spring did you?

If you have your ramp assembly height (mine was 65.99 mm), I can give you the proper thicknesses to use. Assuming the same ramp assembly height as me, you should have used 2x 1.6 mm discs and 1x 1.7 mm discs per side.
