So now that I have your attention........If I decided to just have the rear end rebuilt instead of doing a full swap, what is the best way to go as far rebulding it....gears,..differential system, ratio etc?? What brand do you recommend? Also I have a A4, full exhaust system, intake, other bolt ons etc.

Nothing the 10 bolt is a piece of crap. Rule of thumb is upgrade not to rebuild.

Buy a real rearend, rebuilding the 10 bolt is like throwing money into the wind.

I agree. It would be a waste of money.

Everyone that has posted in this thread is correct, the stock 10 bolt sucks.....If u have the money def get a 9" or a 12 bolt, but yet again not everyone has the $2,500-$3,000 to do this, such as me, lol....I just rebuilt mine, I got all the below parts for a lil over $700 and did it myself.....I do know how to do all this so I wouldn't recommend doin it urself if ur not sure what ur doin, if ya don't it will probably cost ya another $350-400 to have someone do it for ya...And make sure whoever does it, knows what the hell he is doin.

Go to Jegs and by their gears and install kit together and save your money.
I believe they use Richmond gears. Thats what I did last go around.

i put in summit 4.10s in and i love them $125 you cant beat that..but dont spend money to make the 10 bolt stronger you can put alot of money in it and its still going to be a week 10 bolt
