[QUOTE=Adams' Apple] [QUOTE=rraider1] When the repair is done Is it not better to replace the yokes with hardened ones,[/QUOTE]

It's always better to go with the best parts, but it really depends on how the car is used. A "driver", or a car that is used often, will benefit from the hardened yokes for sure. If you're working on garage art, or a car that rarely gets any long distance miles, it may not be all that worth-while.
In the long run, however, you really don't want to have to re-do a diff in a Shark more than once in a lifetime, so the better yokes would be money well spent. [/QUOTE]

[QUOTE=jp75vette]Ok, I moved the Corvette into intensive care and am ready to pull the differential and the half shafts and take it to someone who knows how to fix it right. [/QUOTE] sgm20042008-07-17 07:03:57

I pulled the differential last night and found out that the Yoke retainer clip had come off. I'm not sure how that happened as the clip and the groove in the yoke look OK to me. I see that the splines on the yoke have twisted a little. Is this normal and is the yoke OK?

if the splines have twisted then the yoke isnt ok... cthulhu2008-07-19 06:45:04

The other side clip was still on, I removed it and noticed that the was wear on the end of the yoke shaft, so much that there were burrs on the splines. The splines were straight on this side.

All, yoke came completly out on mine only thing holding mine together was rear supention. Got it all out took it to Zips today T/As and diff. I'm replacing just about everything from wheel to wheel. keep ya posted. Thanks

I talked to a Corvette shop that repairs differentials and when I reviewed my situation, over the phone he said it was the springs that caused all these problems.  I believe he is right as my car had extra wide tires (P295 50R 15's), spacers to prevent these wheels from rubbing on the ebrake cable and also was riding high. I will take it to him to rebuild and have him give me advise on a new spring.
