Well if you're planning to do the install yourself you may want to rethink it. It's not a hard install. I've personally had everything torn down before(never done an actual gear swap though). The problem lies in that you have to have a dial indicator and other fairly expensive tools to check the tolerances. The most important one being backlash. You're dealing with a .005-.010(the exact numbers escape me) or so in precision. If you go outside that window your gears are going to make tons of noise or potentially break ring teeth over time.

In short, if you only plan to do the install once you may want to take it to someone that already has the tools. For the $200 or so in labor they will charge you it would be cheaper than buying all the tolerance checking tools.

ok. i see. i was thinkin that 4.10s would be as easy as buyin the parts and spendin a day installin it. but it looks like theres gonna be more money and hassle involved

Backlash is the last spec that needs held really. It can be adjusted slightly as long as the rest of the set up is right. I have yet to see anyone press a pinion bearing off and resuse it.

yeah pinion depth comes to mind as the most important number to hit...

That's 1st :greg: The others are easierest from there. Side preload usually stays the same.

your truck is a z71? if so you need to change the front gears too.

For parts/labor (complete rebuild) you're lookin at 1500-1800 per axle....which is why i got a low mileage unit from junk yard and swapped whole rear end

Whoa no way man. I'm not sure who you got your quotes from but that is highway robbery. Most places in Texas are going to charge about $400-600 per axle for everything parts and labor to install gears.

$1500-1800 per axle is accurate with GM gears and bearings at full list with dealer labor but half that for aftermarket parts and side job labor.

I usually charge 250.00 for setup/install plus parts. So on average 200.00 for gears, 85.00 for install kit, and 250.00 for labor.

That's a really good price!! I suppose the cost of gears and install kit is going to depend on what all you get.

If you got Yukon or AAM gears it's going to be more expensive than summit brand or motive gears.
