Nice setup.

I'm just going to rebuild and check it maybe once a year during fluid change.

If it tears up again, I will move on to something better.

Sorry to hear bout your luck .

Now I m nervous about mine even though I hardly have many miles on it.
Hope some of their engineers will find a solution and offer it to us customers.

Really the best solution is to put a piece of weld in the gears so that the C clip cant rotate(I thought I had a pic of this, but couldnt find it). The C clips need to be new, and not warn at all. Then the plug that goes between the axles needs to slide in very snug. It cant just fall in place, you need to have to push it in place. When that plug fits in place tight it holds the axles out keeping the gear away from the housing.

My 10 bolt has me a bit scared as well between the tq of a big block and spray,only time will tell.my friend told me to cut the ends off my axle tubes and replace with 12 bolt style for c-clip elim. And switch to a spool and get rid of the c-clips.

If I can't get the weld on the gear, I think the next best thing is to replace the C-clips once a year when you change the fluid.

By the way...when I dis-mantle the Tru Trac, what torque specs do I use on all the carrier bolts ?

Also are the caps around 50-55 lbs ?

Thanks for the info and advice Daryl !!!

Thx. I would just keep a check on yours as I mention and you should be good to go. My c-clips had a deep groove in them.

That should do it

I ordered a Carrier Super Shim kit from National Drivetrain for $34 shipped, and will get the C-clips from GM for $6. NAPA no longer carries them.

Hopefully these parts, and some case clean up will get me back rolling.

This is what the inside of my case looked like from the gear rubbing. Notice the first pic has 3 oil valleys and the other side only has 1...go figure ??





After cleanup as much as possible:





Waiting on new carrier shims now and I will slap it back together. In case anyone else has a Tru-Trac diff, be sure to change out the axle C-clips
every year or so to help keep this from becoming an issue. Seems to me this could have been designed with a Trunnion Bearing to keep the gear from ever touching the case. My last LS2 timing chain sprocket was designed like that. I think it was a Jennings.

Both sides of my unit had 3 oil grooves. I doubt they changed the design. Check to see if they are full of debris.
