installing posi and gears

[ridge_runner]

ive been lookin into redoing my rear, right now its a stock rear, i have a brand new torsen posi unit and im tryin to get a deal on some 4.10s, i have never done anything like this b4, but i want to learn, i plan on doing this in my garage, anyone ever done this b4? should i attempt myself or take it somewhere, any advice is appreaciated

i am also curious. as eventually i would like to swap both. but wouldnt it be a bit much for doing in the garage

ring and pinion swaps are pretty straight forward. remove the pinion shaft, push the axles in, take off the C-clips and pull the axles out. you dont have to take the wheels off to get the axles out, but it might make it a little easier. take out the carrier mains and pull the carrier out. to get the pinion out, take off the u-joint carrier and then drive the pinion out with block of wood and a hammer or something. take the ring gear off the carrier and put the new one on. the bolts that hold the ring gear on are left hand thread, just incase the instructions dont tell ya that. the pinion depth should be etched on the face of the pinion and you adjust that with an in depth micrometer or a slide micrometer, and you adjust that by using shims. then adjust the clearance between the ring and pinion.

see thats the only thing i think that im gona have trouble with, the pinion depth, i dunno what a depth micrometer even looks like and how it works, and what is pinion depth

[4onFloor]

as your looking into the housing, the pinion depth is the distance from the face of the pinion to the centerline of the axles. an in depth micrometer looks like an inside micrometer, like what you might use to measure the bores on an engine, except it's usually got a dial indicator. a slide micrometer works just as well. you could probly rent either one from a parts store.

oooo ok i gotcha now, how much would a micrometer run me?

[ridge_runner]

i think im jus gonna put my stock gears back in along with the posi, make sure it holds up good and i did it right b4 i put the 4.10s in

[Chevyracincamaro]

arent 4.10 gears 8th mile gears?

[ridge_runner]

hmm im not sure....

[ridge_runner]

i kno quite a few people that use 4.10s in the 1/4 mile tho and people that use them for driving on the street, alot of s10s and blazers came with 4.10s

[Chevyracincamaro]

oh wait, nevermind, im thinking of 5.12 gears...sorry

[ridge_runner]

ha yea its all good

yeah the job is pretty easy, i did my first one in three hours, but i was definately working slowly cuz it was a customer car that i didnt want to screw up. and i didnt have to reset the shims or clearance anything cuz all i was replacing were the bearings. i recomend finding someone near by with experience to at least hang out and drink a beer while you do it, its not a hard job, but its nice to have someone around to doubble check shit with ya know? also, your gonna need a hydrolic press to take off, and put on the pinion bearing. also invest in a bearing spacer setup kit, jegs sells one, its bearings that are easy to slide on and off the pinion, so you can save time checking your spacing, without having to press the bearing on and off and on and off and shit. but take your time, and recheck everything three times at least as you go along, and expect to have to pull it back apart after you put it all together the first time. and youll probly do fine.

[ridge_runner]

yea it doesnt seem that hard, ive had people around here telling me its hard and to take it somewhere and i dont wanna do that, someone said i could get done for 200 bucks, fu*k that, i dont really no anyone who has done a rear b4, well i do but i dont trust this guy cause he messed up my firing order one time and wondered y the car wouldnt run... i do have a friend that can help, hes helped me with alot of shit on this car, i help him with his s10 so he helps me with my camaro, those bearing spacers sound useful, and i have a local base hobby shop with a press anything to save me some money... i need every that i can get

sounds like a plan id also hit up the websearches to find a step by step description of a rear end swap, im sure any company that specializes in rear gears could help ya out with that.
