The kick-ass shop near me usually charges $250, NOT including anything they need once they open the rear up. They will call if they think the bearings are toast and whatnot.

I would go up to a reputable shop and pull one of the guys aside and ask him if he'll work off the clock. I did this and only paid $150+parts.

It takes longer if you have to pull it back out and change out shims, especially the pinion shim. Also depends on what the tolerances are on the gears.

I'd recommend looking for a very reputable gear installer, rather than someone who will do it cheap. I've read horror stories of rear ends blowing up after gear installs.

That is one thing that I might want done on the clock so it would have some sort of warranty.

From my experiences it'll be bwteeen $250 and $350 to go through a decent shop. Very worth it for a proper install!

i have no problem paying for it to be done right. are there any downsides to having 4.10s to having 3.42s?

I can't recall are you A4 or M6? 4.10's are too much for an A4 if it's a driver. Considering the near accident you were in today you really don't need the added torque multiplication the 4.10's will give you...

IMO, 3.42 for A4, and 3.73 for M6 are perfect choices.

The guy who did mine, is the best guy in our area. He does hundreds of installs a year. He will do 2 a day. It is roughly a 4 hour job for him. Sometimes they are perfect right off the bat, other times he has to adjust them several times to get them perfect.

The only downside, aside from less gas mileage, is that 4.10s will be weaker because of a smaller contact patch on the pinion teeth.

**Thread Hijack Warning**

I just got a set of 3.90's for my truck today... I can't stand the stock 3.42's when I put the 295/45/22's on it. They make my effective gear ratio like 2.50 when they are on there. Has to downshift every damn hill I go up. Should pull the trailer and boat a ton better with the 3.90's.

I'm installing them myself.
