I'm looking to swap my 3.08 gears to 3.73 in my 2011 Sierra. I'd like it to tow a bit better and have a little better low end.
I busted my front axle in an unfortunate floor jack incident and picked up a 3.73 front from a suburban. I still have the 3.07s in the front and used the 'burb axle to fix my broken parts. So i'm still geared the same front and back for those that were worried.
I have found locally an axle with a busted g80 that has 3.73s and all of the same RPO codes as my truck. So it would swap in fairly easily from that stand point.
But, I would need to fix the carrier. The idea here is to go with the Yukon duragrip and a rebuild kit. Since I would be rebuilding this axle on the bench I feel like i could take my time and get it done myself.
I do have a few questions hence the post.
1. As far as pinion depth. I should be able to reuse the spacers on the current pinion to set my depth correctly from the start because that is housing specific. Is this correct?
2. Since I am putting in a new carrier the main bearing shims would be a start but it would need to be set for new carrier. Is this correct?
3. When setting up used gears the coast side of the pattern is more important?
4. Has any one successfully used the heat up the bearings process to install the new bearings?
I know we have a few axle experts on here. I also know even the most hard core DIYers seen to shy way from axles.
