    what to do? I\'m getting sick of this subject

    I am currently stuck on what to do. I have just chewed up my ring and pinion gear in my corp 10 bolt with 3.07 gears. I am running 33's with about 3 inch lift. I read some reviews about getting a 12 bolt. The Blazer is in the shop as of yesterday. The mechanic say's to leave the 10 bolt in and get 3.73 gears. I was looking into getting a 12 bolt used with 3.73 but nobody has one around Fremont, CA. One guy has a remanufactured one for $650. Should I just keep the 10 bolt re-gear it front and back, or get the 12 bolt? I'm short on $$$ so I'm sitting at home with no ride. I use the Blazer as a dailey driver/camping rig. I don't do hardcore wheeling or rock climbing! What to do? I'll be right back...

    If you are short on cash, just get new ring and pinion for the same gear ratio you had before. Stick with the 10B for now, and when more funds allow, get the beefier set up later.

    If you have the money available to you, go ahead and get the 12 bolt. I wish I could find a good 12 bolt around hear.

    Re: what to do? I\'m getting sick of this subject

    I've HEARD that the 12/10 bolt difference is slight..the 10 bolt has a thicker pinion or some such...personally, I'd put 3.73's or so back in it. But if you are going to be really hard on it, you are eventaully going to have to upgrade the entire axle assembly to a 14 or dana 60. I bet others are going to say the same thing : ) BTW, a cheap source of 3.42 axle assemblies is the mid 80's suburbans. They were a very common stock ratio then.

    Re: what to do? I\'m getting sick of this subject

    Dude, just keep your 10 bolts and put 3.73 or 4.10's in there and be done with it. YOu are going to be looking at about 500 per diff to rebuild, parts and labor. Do the rear for now, then save and then do the front. PERIOD, END OF STORY. NEXT POST?

    Will work for beer, parts and tools.

    Yeah it's not worth getting a 12B over your 10B, especially for $600. That's a little high. I wouldn't trade your 10 in on anything less than a 14FF, 14SF, or D60

    for that $600 you should be able to upgrade to 3/4 ton axles.
    around here you can get a set for that from a private party
    and get better gears to boot. Most are 3.73 or 4.10.

    Re: what to do? I\'m getting sick of this subject

    I had to replace my 10 b guts and it ended up costing me about 1K. Only thing salvagable were the axels. carraige and gears were toast. I changed from 2.73 ratio to 3.73. so the front had to be changed also. New gears were about 200 a set plus about 40 for the install kit. the carrige was about $400 (eaton posi). what a pain to buy and install. all thankz to West Coast Differentials www.differentials.com


    if you aint got tools dont buy it!!!!!!!!!! mb

    Yeah, so the shop is going to change the rear for no fee (my dad's buddy) then over the weekend my dad and I are going to try to change the front gears. What am I going to get into? Need any special tool's? step by step would be great...
    It's a stock 10 bolt with 3.07 gears changing to 3.73

    Blinker- I'm in Hesperia, CA. I know a guy in Fontana with 2 12 bolts. I was going to buy one for $250 or $300, I don't remember. Get a hold of me if interested and I'll go find out.

    Re: what to do? I\'m getting sick of this subject

    Hey Mud Bath, I gotta couple questions since i gotta have some inards replaced on my 10B.

    Did that 1000 include the axle shafts?? Or just stuff in the pumpkin. I got a quote of 800-1000 for just replacing stuff in the pumpkin (not even ring and pinion) and I think it might be a little high.

    I didn't get from your post whether or not you were happy with www.differentials.com. Was the good install stuff thanks to them or the pain from them [​IMG].

    Thanks!!
