Just FYI, $800-1000 is pretty standard on NEW axle parts, done correctly with fresh seals and bearings.

Ive done a lot of research when mine went, and thats going rate. $150 for the ring and pinion, $150 for the master seal and bearing kit, the rest is labor.
And yes, it sucks to do the front, the rear isnt as bad, but the front is a *^&#...

I ordered mine from 2 different companies, Had the rear done by a shop because i needed it on the road, they charged me $850 out the door, the second time, when i got to the front, i picked up a new third with new gears, seals and bearings for $800, and did the install myself and saved about $400.
