DAYUMMMM!! Did that once to a rear. Spun out in the snow, and 1 wheel hit the curb, pushed the axle into the ring gear and everything associated. Was holding on by a hair. Drove it for a yr before it finally exploded. Looked like a huge jigsaw puzzle. Mechanic, who used to race, said he's never seen anyone do that to a rear before! Lol, I was damn proud

Drum size comparison. 10 bolt drum on a 14 bolt. Big difference

Will the offset on your old rims work with the new rear?

Haha oh man, I think if anything the axle wider, but I’m pretty sure they are the same width

My first car was a 92 k2500. I wish I better understood back then what a beast it was. Thanks dad for the hand-me-down!

Nice progress dude!

Alright guys, more issues arise! Transmission time... let’s hear everyone’s input!

Haven’t pulled the pan yet, but I only have 3rd gear. The other day it would start in 3rd, and when I stepped on the throttle it would downshift to 1st, then 2nd, and quick shift into 3rd. But then at times it acted normal. Started truck up on Saturday and it won’t come out of 3rd gear. So it starts in 3rd and drives in 3rd. Nothing changes when I manually shift. I have Reverse, as well. I have cleared the adaptive tables to try and take it out of possible limp mode, and that did nothing. Supposedly this transmission defaults to 2nd when in limp mode, but I am most definitely in 3rd.

Any input is greatly appreciated!
