calculated above without going over, and replace the ones you
measured with.
NOTE : The objective here is only to attain a slip fit between
the thrust block and the axles without any slop (too
loose) or binding (too tight). You may find that the
smallest 2.80mm [0.110”] clips are the best size.
Leave them installed in this case.
F Insert the thrust block into the center of the spider block and then
insert them both onto the short cross shaft.
F Insert the long cross shaft maintaining alignment between the cross
shaft retaining pinhole in the differential and its corresponding hole
in the cross shaft.
NOTE : Make sure the pinion thrust washers are not
misaligned with the cross shaft holes when inserting
the cross shaft.
F Insert the cross shaft retaining pin and tighten.
F Reinstall the drive shaft.
F Reassemble the brakes and wheels according to your vehicle’s
service manual.
