Greasing the won't change the play so measure them before you take them apart and change shims if needed.

Subject: LM Rear Suspension and Diff Questions
I'm finally getting some time to address some needed service and possible
adjustments to my '66 Corsa. It's a 140 with a 4 spd and posi-traction.
It has about 67,000 miles on it.
I removed the power train to re-seal the engine but I also wanted to
re-pack the rear wheel bearings and will be replacing the suspension
My questions are:
1) I want to re-pack the rear wheel bearings but I'm concerned about
getting the bearing end play/preload reset correctly after service. It
looks like there is a spacer and shim(s) used to set this end play. Do the
factory set-ups hold the correct end play after a bearing service or do I
have to buy a number of shims to re-adjust the end play? I'm guessing
normal wear may increase the end play and I would have to put in a thinner
2) I'd also like to tighten up some of the end play in the half shaft yokes
(rear suspension looseness). The left side has .037" and the right side
has .024". This seems high but according to Mr R. A. Kirkman's article in
the Tech Guide Supplement, is probably normal for a used vehicle. Looking
at the exploded view in the shop manual, I see that a shim behind the yoke
retaining nut might correct this but I'm not sure if it's even possible. I
know we all live with this end play but are there any tricks learned over
the years that may improve the condition?
Thanks very much!
