I ran the differential out of oil. The pinion gear and ring gear were destroyed. I took it apart and put in new pinion and carrier bearings along with the new ring and pinion gears. I used a new crush sleeve on the pinion. I used the 2 oem shims on the differential. The lash came out at 10 thousands. The factory spec is 5-9 thousands. The gear pattern is perfect.Rightin the middle.Without any pinion depth adjustment. ### ⭐⭐⭐⭐⭐ Notice for GM 12 bolt C10 diff install *by R***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on August 3, 2019* These gears appear to be good quality and the wear pattern looks the best I've ever seen after adjustment. I have a 12 bolt 8.875 GM truck rear in my '67 C10. All 3 of my C10's, '67, '68, '69 2wd trucks had 3.08 factory installed gears. I guess because of only a 3 speed auto trans in my '67 and '68, it was better on the highway. My '69 is a 3 speed manual. I decided that since I built a 383 stroker small block and installed a 3000 rpm stall converter in the TH400, due to the cam profile, I would replace the 3.08 geared, one wheel peel with a 3.73 gear and a Spartan "lunch box" locker. I'm just about to fire this thing up in a week or two. Just waiting on the machine shop to do the final piston fit honing and it ready to assemble, stab it in, hook everything up, start it up, and hold onto my hat.But I digress. Sorry, lost track. Anyhow, changing the gears from 3.08 to 3.73 I obviously had to re-shim my carrier to move it to the left. The factory shims were just about equal from one side to the other. Left being a .230 and right being a .243 thickness. I had to bring my left side to .445 and the right only has .024 gap in order to get my .006-.010 backlash needed for a good pattern. I even had to shim my pinion an additional .030 just to get it right. It's not quite a tight fit as factory, but I don't have a housing spreader and the 3 very thin .008 shims were giving a fit without trying to fold over on me. I don't think .004" is going to give me any trouble. Especially with the Moser girdled diff cover I'm using.Okay, here's the issue I ran into. Being that I needed to shift the carrier over almost a quarter inch, the right side of the carrier was hitting the area just outside and to the front of the bore for the carrier bearing. So, I removed the carrier and used a dremel tool to slightly grind the carrier housing on the four 'corners' where the bearing is pressed on. I took off about .100" on each edge and it then fit like a glove. I got my backlash to .008". Installed the yoke with a new crush sleeve and torqued the pinion nut to 11 in.lbs. Re-installed my carrier and torqued the caps to 60 ft.lbs. and installed the diff girdle cover.Hint to the next guy that decides to rebuild a differential. Purchase some cheap new pinion bearings in addition to the bearings that you are going to install. Grind the inner race of the cheap bearings so they slide over the pinion without being pressed on. This will save a bunch of time and frustration when adjusting or shimming the pinion depth. When it's all clocked in, just remove the dummy bearings and press the final good bearings onto the pinion. Oh, btw, the spartan locker is a pain in the butt to install with the diff housing in the vehicle. If possible, remove it and set it on a bench or jack stands with the yoke facing the floor. It's much easier to articulate the c-clips this way as long as you hold your tongue right. Good luck ### ⭐⭐⭐⭐ Very loud gears but performs well *by A***S on Reviewed in the United States πŸ‡ΊπŸ‡Έ on March 10, 2023* The price was right. This is not a daily driver for me. Good strength under lots of load, pulls well. However, these gears are loud. Didn’t come with any numbers for the pinion depth install as other pinions would. Gets the job done for little money.
