My 9bolt has been sitting outside for the past like 3 months with no diff. cover or axles in (didnt even stuff a rag in them) its been raining on and off down here so I guess I should rebuild it.... also gives me an excuse to put some better gears in it... their 2.43 or something like that.... what do I need to know, as in proper disassembly and tolerances, torque specs, re-assembly, etc. OH and where to get some better gears

Talk to Miles, he's a member. You need a service manual for the real how to info.

i just used larry's shims, if your posi is loose its the cheapest way to go. Mine was totally shot and now i leave 2 beutiful stripes where ever i go!!!

 

Thanks Laiky!
did you use the factory spec from the case connecting half? or just threw in shims until there was minimal gear lash??


on a side note.... a lot of people ask me for information on how rebuild the 9bolt.

there is a tech article here on 3rd gen that explains it pretty well, and the FACTORY service manual explains it as well. you really need both to understand it fully. I throw in a copy of the factory service manual 9bolt pages with every shim order.

i tried to get to the factory spec but i didn't have enough shims, i'm about .025 short between both sides. it works very well though. I'm going to drive it for now and see how it wears.

 

I do have .035, or something like that thick.

I'm surprised yours works so well being .025 short. should have called me next time around....

 

I thought about calling you but it was Thanksgiving and i was desperate to get it done. Now that i know what i'm doing i figure i can do it in a coulple of hours.

i got some pics if anybody is interested.

 

In the thicker sizes, like .044 I have some AN4 hardened shims. I don't even know what the AN4 material stands for, but they cost me like $7-8 each. I think it may be an aircraft grade material or something like that.

The first time is always a learning experience. I did mine when I replaced my gas tank, and exhaust system. so my car was apart for 2 months. especially since I didn't gather up the parts before hand. It was in the middle of the winter too, so I waited for warm days.......

Yeah, AN is aircraft grade, AN4 hardened or whatever my dad was talking about (he's a&p)
