Today I finished up all the fab work that was on my before Blazer Bash to do list. The big job was replacing the drivers side inner C. I noticed last time I did the ball joints that the adjuster sleeve was tightening way to far down and this allowed the ball joint to wobble loose over time. I tack welded the castle nut in and started looking for a replacement C (it's the older 2.75" tube D44 so it's a little harder to come by). I ended up having ORD ship me a C from an old housing they had laying around.
When I pulled the knuckle apart I found that the tack welds had broken and the nut was just sitting there finger tight (it had sheared off the cotter pin). I've checked it a few times since I did that, but obviously it broke loose at some point. You can see in this picture how far the adjuster sleeve is protruding through the bottom of the C.
I had to remove half of my coilover bracket to get the C off, then the old c was removed and the axle was cleaned up.
The replacement C was tossed in the oven at 250°F for a half an hour and I iced down the tube to make positioning the C easier, then it was set back at the same position the old one was at.
A replacement shock mount tab was fabbed up and the C and shock tabs were welded back in place.
I was thinking about the brace I added yesterday and decided I wanted to add some gussets to my truss. I cut a big chunk of the truss off to make room for the coil perches so I wanted to attach it to the axle tubes better than it was. I think this combined with the brace I added to the diff cover should give me plenty of strength for the upper link mounts now.
Now I'm off to the lake for another shakedown run.
