Rebuilding my rear-end and am having an impossible time finding the correct disc/shim pack. Some of the carbon fiber pads went missing on my disks. - no trace of them now.

Called the Chevy dealer and they only have a part number for the entire carrier unit (88965671 - discontinued), but no information on the discs.

Aftermarket Eaton units for GM 9.5" - 14 bolt use kit (29418-00S). These are back-ordered everywhere. This is the only picture I could find, and this looks exactly like what is installed:
Automotive tire Coil Rim Spiral Circle

~$170 plus shipping from Summit Racing.

Yukon also has a kit for ~$338 (ouch!) which they advertise as superior to OEM (YPKGM9.5-PC-14).
Food Coil spring Baked goods Font Automotive tire


Has anyone been down this road before and maybe has some recommendations?

I put Yukon 4.56 gears in Kate.
They were the most expensive but it was not something I wanted to do twice!
Not a sound out of them

Did you change your positraction clutch/disks/shims while you were in there?

I'm guessing the Eaton kit, which is on backorder, is what Summit lists for $170. I guess you've tried some of the big wholesale vendors like RockAuto, PartsGeek, carparts.com and Carid? There are others as well. Maybe Southwest Performance Parts.

I called Eaton Technical Support and sent him a picture. He said it looks like the aftermarket Eaton 19590-010 Posi Unit minus the pre-load plates and springs shown with red arrows below:
Automotive tire Product Wheel Font Automotive wheel system
Automotive tire Bicycle part Rim Engineering Automotive wheel system

I have been calling shops. Even when their website says "in stock" it is back-ordered.

I just hate to button it all back up until August just to break it all back down to put the plates in.

I have called a few. I actually rebuilt it in my my buddy's shop who is a manual tranny and rear axle specialist. He made me pull the rear-end so we could work in his air conditioned shop since his lift is outside!

He called several of his suppliers also - nothing.

The Eaton Technical Support Rep was even trying to talk me into junking the unit and replacing it with a new Eaton Truetrac differential!

230k miles - had a slight whine in the rear and the axle seals were oh so slightly seeping oil.

The noise ended up being the gear side carrier bearing:
Automotive lighting Rim Jewellery Automotive wheel system Machine

Gas Jewellery Auto part Nickel Automotive wheel system


Both of the carrier bearings were Timken - made in Brazil. The rest of the bearings were made in USA and in great shape.

So, the problems I found were:
-bad carrier bearing
-seeping axle seals
-missing carbons pads from discs
Everything else was in very good condition.

For those considering a rebuild, here is the list of parts I used:

4.10 GM gearset - (88967095) - Ebay - $350
Motive Gear, Master Rebuild Kit (all made in USA Timken bearings) - (R9.5GRLMKT) - Summit Racing - $187.61
ACDelco Wheel Bearing - (RW20-10) - Amazon - $36.97 (x2)
GM Genuine Axle Seals - (291-315) - Amazon - $9.25 (x2)
GM Genuine Pinion Seal - (26064029) - Amazon - $15.07
ACDelco Limited Slip Lube 4 oz - (10-4003) - Amazon - $10.39 (x2)
ACDelco Gear Oil GL-5 1 gal - (10-4099) - Amazon - $38.49

Even though a new pinion seal was included in the rebuild kit, the OEM one wasn't even seeping with that many miles. I decided it was worth $15 extra bucks for a seal proven to last.

I had cross-referenced the wrong clutch pack and am returning it.

I had the same problem, clutch disc set took 2 months to get, have a high pitch whine in the rear diff. Still not fixed.
replaced:
carbon fiber clutch set
diff bearing kit
diff ring & pinion kit
pinion seal
diff crush sleeve
Sent the drive shaft out to check balance, says it out of balance. Aluminum drive shaft says they cannot balance it. needs replacement.
At this point had to get the truck back, taking it to a trans/ rear diff specialist shop.
Last ditch effort.

I about ready to junk this truck, more problems that whats it worth.
Purchased in December, driven for two months and has been down since March.

Tony,
Does your six speed ride have the stock 373 gear set or has it been changed to maybe 456. I've gone thru multiple different (after market) ring and pinion sets in 456 and all have been noisy to one degree or another. My stock 373 before the swap was quiet as a mouse.

It's stock 373 gears
Mine was quiet also until I had the rear diff fluid changed, driving back from Laughlin, NV the noise occurred. Fluid change was more coincidental

For others looking for parts I recommended Tom's Differentials to MidBubSC. I run a 12 Chevy rear end in both of my Chevelles and have been dealing with Tom's for years. They have always taken care of me on the 12 bolt Eaton stuff.
