Very nice welds.

Some of them look better than others, and naturally I chose the nicest one for the photo.

I can't weld at all. Wish I did.

Nice work cleaning that rearend up. I'm guessing your least aesthetic weld was 1000x better than the booger welds you have ground off that truck.

Love the consistent progress you're making.

Thank you. I'm looking forward to having the rear end back in place.

Installed the front carrier and pinion bearings. Thankfully, my wife is entertained when I "cook" car parts.

**pjmoreland** · 11-08-2024, 12:12 AM

Cleaned up the rear leaf springs and u-bolts with a wire wheel and then painted them. It appears that there is a GMC logo on the u-bolt saddles.

U-bolts and retainers

Interesting. I did a search on the part number, and I saw a thread that says these cast pieces like to break in half. I'll take my chances for now, but I should probably replace them eventually.

Yes, I have broken one. When tightening them, you must tighten slowly and evenly or they will easily break. My donor Blazer supplied another one for the project. 1967-68 trucks did not use these.

Reattached the rear axle to the leaf springs.

**pjmoreland** · 11-10-2024, 01:48 AM

Spent some time working on the front axle today. Cleaned some rust out od the inside of the housing. Gave the outside a quick cleaning with a wire wheel and sprayed some paint on it. There was a decent sized dent in the diff cover that I straightened out using the Hydraulic press. That cover is thick.

Also cleaned up and painted the rear brake components with high-temp paint.

Dude, you're an Artist. You sculpt Chevy Trucks out of rusty steel.

**CUSTOM/10** · 11-10-2024, 08:06 AM

Nice work on rebuilding those differentials Patrick !!!
I just completed doing both of mine and it's a lot, but you made it look quick & easy...
Amazing progress !!! Keep it going.

I have this special tool that transfers the rust from the truck to my face.

The way the shims go behind the bearings on this Dana 44 looks like a real pain compared to a 12-bolt. It would be nice if everything is still in spec using the same shims, but I doubt I'll be that lucky.

I have a similar relationship with Gear Lube.

Seriously -- wear safety glasses.

**pjmoreland** · 11-13-2024, 12:45 AM

It's chilly outside this evening, so I wasn't very excited to be out there laying on the asphalt, but I went ahead and did it anyway. Got the front differential reassembled. The pinion preload and the carrier backlash are good. The carrier preload is good and tight. The gear pattern could be better, but I can tell that it matches the wear marks on the teeth, so I'm not going to mess with it. It feels smooth when rotated.

Those shims are a PITA... I honed out a set of bearings & races to a slip fit to mock-up the gear pattern. I was changing the gear ratio so the shims were totally different. It was still a PITA.

Good looking work.
