Installed just Ring and Pinion?
Has anybody ever Installed just the Ring and Pinion and not the entire pumpkin?
This looks like a much cheaper way to go. Would there be any whining issues due to incorrect back lash?
Thanks!

Make sure you have someone install the gears that know what they are doing, incorrect backlash settings will result in excess noise.... and yes just gears would be cheaper.

I don't believe you can simply swap gears in a C5. You need to replace the whole unit.

You can purchase and install just the ring and pinion. But, unlike rears of the past this one is quite finicky and it takes someone who has done a C5 rear a few times to get it right. That is why most people just replace the entire unit. If you have a good shop in your area that has done a few before and can get it right the first time then by all means go with just the ring and pinion. But, from what I've read here, even the good shops still have problems with gear whine sometimes.
Best of luck.

I had a 4.10 ring and pinion swapped into mine. The gear set was inexpensive but the labor killed me. All-in-all if you can find a complete carrier containing the ratio you need, thats a much easier swap. In the long run I think you will find the total costs comparable.

I'm really ignorant when it comes to gears, so:
1)Is the gear whining the same with 3.90 as it is with 4.10?
2) If your rear end was relatively new (10.5K miles in my case), would you rather keep it and change the ring & pinion or would you exchange it for a rebuilt one?

Howdy!
I have heard/read that the higher (numerical) gears have "steeper" angles (than lower gears), and that steeper angle generates more whine/friction. (so 4:10's would be noiser than say 3:73's)
I have no experience with this myself, just read it a few times.
Any truth to this?

Gear Swap in any diff must be done right, with the proper tools and knowledge. I’ve built more than quite a few diffs from C2’s up to current. Granted, the C5/C6 diff is different in allot of ways, fundamentally it’s the same beast. Gear noise is due to improper pinion to ring relationship more so than backlash. The patterns that I get on the C5’s are never quite as sweet as those I typically get with Dana gear sets in C4 Dana 44 cases. Ask me again after I build 10 more, that could change.
Break in is a funny subject..I’ve built diffs for guys that hammered them mercilessly from day one without problem…..I run my new diffs easy for a short while….and then hammer them mercilessly.
The C5/C6 diff requires a bunch of unique set-up, build and measurement tools. Is it Voodoo?...No…It’s just new and different. To date, the rebuild kits available don’t contain all the necessary shims. I’m machining the pinion bearing preload shims myself. Can your typical local gear shop do it?...maybe not…..But there’s’ plenty of guys like me doing it right I’m sure.
