another diff question -D36
So, I have finally got my new differential gearset installed, did it by removing the old bearings, grinding out the inside a bit so they would fit over the shafts with hand pressure, and trial and error to give correct tooth pattern and backlash. Then I pressed on the new bearings using the same shims.
Anyhow, here's the question - do I need to install the circlips on the stub axles. According to Tom Falkener at Claremont Corvette, and Tony Morgan at Cas Am, they are better left out, since they serve no function but to hold the stubs in during delivery and transportation of the diff assembly. If they break up in use they will cause mega damage to the diff. Probably.
Any thoughts?

Ask Jessie (ski-dwn-it) what happens when you don't retain the half shaft yoke shafts. Are you beginning to understand why this job is best left to those with the experience and tools? I've got my fingers crossed for you AND this diff.

there are special gauges and dials that are used to set gears. it's not something done by trial and error, unless you are a) lucky as hell or b) rich, and can afford new gears.
get that gear set to someone with tools...

Maybe it's just me, but do I sense a bit of negativity here.
Oh - and yes, discouraging though it may be, within these parameters, I am rich. This is MY car. I do the work. Give me the info - I will take the consequences.
Thanks for the help and info though, it has been genuinely useful, and for that I thank you both.

we have left the clip out of every C3 and C4 rear we have done. they do not serve any purpose unless it breaks a half shaft

I guess you have your choice. It makes me wonder why there is a spec for the shaft end play and different thickness snap rings offered?

Differing opinions or not, this is a job best left to a pro who knows the procedure, not in your backyard.
A local guy charges a flat rate of $150 to do a gear swap. I think it's worth it to have it done correctly.....the first time.

My guess is this, the one without the clips was flirting with disaster.
