I disagree with this, that's how I've learned how to work on cars pretty much my whole life. if your methodical and a do it right the first time kind of person, then I'd say go for it but do your homework and like someone said before have a friend that's done it before help. There are some books in the library that can help also. I'd look for that.

Just a note, so you don't think I've done one before because I have not. I've always been into sports cars and my 2012 will be my first time doing a regear but that won't be for another 6 months or so.

 

I found this write-up https://www.jk-forum.com/forums/jk-w...gearing-82262/

It was extremely detailed and told me that I have neither the time, tools or the patience to do it myself. If the opportunity presented itself to learn from or with someone that had experience I'd jump on the chance but doing on my own.. Nope!

 

You can regear sports cars too , but in my last sports car it was cheaper to just swap the pumpkin for one with a higher (numerically) gear than pay someone to regear it.

 

I had never done gear before but have done stuff like suspensions and minor motor work.

Don't crush the sleeve unless you have the shims and backlash set that is the last step. The crush sleeve is there to maintain preload. You can get the bearing load by wrench to test rotational inch/lb torque. The crush sleeve is used once everything is set to make sure preload is constant.

U doubled up 2 .75 inch by .25 inch thick pieces of angle iron that were long enough to rest on the ground drilled two holes for factory bolts and had to notch it a lil for the socket while i used a breaker bar and cheater pipe. The crush sleeve takes upwards of 350 lb/ ft of torque its not easy.
Be prepared to get replacement bolts as i bent all of mine even the angle iron a bit.

All in all a good install i have zero noise or issues. It took basically a day an axle to make absolutely sure tolerances where tight

Hope this helps

 

Setting up gears is one of the most commonly messed up jobs. This is not a matter of removing one part and installing another. Crucial, precise measurements and adjustments must be made to prevent accelerated wear and/or noisy gears. We get calls all the time asking for advice on setting up gears. It takes special tools to do it right and can take a lot of time to get the pattern right. It's always best to have a gear guy help you your first time (maybe even the second time!).

 

Thanks for all the replies so far. I've got a buddy lined up that's a certified mechanic and does regears for his shop. He said it was something we could do. What should I be looking at in the way of purchasing...2012 2dr sport, auto trans, Dana 30 (F), Dana 44 (R), 3.12 stock gears...

Call David at Northridge.. He'll give you great prices. If you have a spreader and a dial indicator the job is not that hard (obviously you need the rest of the tools as well)
