I've looked and haven't been able to find any specific threads regarding gear swaps. I've never played with gears in a reared before. I'm not doing it anytime soon. This thread will be here to basically collect data for now and document my experiences once I get into it.
I'm sick of the 3.55 gears in my 89 crewcab for towing and will be swapping in a set of 4.10's out of an 88 rear axle. I've had a 4.10 rear end with locker sitting in the trees for years. Like 15. So I'm grabbing the gears and carrier from the housing and swapping them in. In retrospect I could have cleaned up that axle for the crewcab rebuild, but I've already got my axle cleaned and painted. I've also got a set of 4.10 gears that came out of my Dana 60 15 years ago to reinstall, but those will probably be another thread we'll see how it goes.
So what I'm reading is to start out by installing the gears and shims just as they came out of the other axle. Then check pattern and go from there. I'm hoping this isn't a complete start from the beginning with shimming, but if it goes that way I'll get it done. I've got or have access to a great selection of tools so I'm not worried about that. I do need to grab a dial style in-lb torque wrench though.
Parts I need
Prussian blue Gear marking - Got some coming
Crush sleeve eliminator - Heard this is the same one as in a 9"? Is that right
Shims - I may wait to order these until I get an initial read on the gears
Pinion nut
So how hard is this? My biggest concern at this time is getting the pinion preload set right. But with a crush sleeve eliminator that seems easier. I know Iv'e read something from Typ4 on this, but can't find the post.
Heres the gears and carrier. Don't worry the little bit of surface rust is only on the outside of the carrier. Gears and bearings look new.
