C2 rattle (clunk) in rear end

(1/4) > >>

anychevy:
Thought this was just a loose spare carrier (it's not)
Pulled the wheels off, took the weight off the control arms and noticed I could pull the half shaft yokes out of the diff
~1/2" on the LHS and ~1/4" on the RHS ?
I read over on CF this amount of end play is not normal, but also not dangerous (not going to fall out)
Could this rattle (clunking) noise be the yoke slamming back into the diff over bumps ?
Anyone have any experience with this ?

I had a noise in the rear  of  a 70 model  recently
and looking into the problem I came up with some specs
that end play the i found  for the yoke  
was listed at no more than 1mm (0.040" )
but I also found 0.3mm (0.012" )

I have one car that has 3/16" and has no noises at all.

With the wheels on the ground and the jack under the leaf, one side at a time.
I can rock the LHS wheel and move the yoke in and out of the diff around 1/2"
The RHS has no noticeable end play when I do the same thing.
So I'm thinking the C clip (or whatever type of retainer is used) is broken or worn out.
Or the trailing arm bushes are gone, or both ?

bfit:
Dave  I have not  pulled the diff apart  in a vette yet
Buy if you take the half shaft out  of the LHS  and the clip is gone or broken
I would think you could pull the yoke out

May be some one who has had a Diff  apart could confirm if that is true

If the diff has to come out I can see that is not a small job

It looks like you can get to the guts with most of the housing still in.
Still a fairly big job that I don't have the tools for.
I'll have to get it towed, can anyone recommend a place in Sydney ? :shake:
