Re: Gears, bearing, seals, labor

A rough estimate is about $500 parts and labor to have it changed for you. If you go with the eaton posi of course it will be more.

You can use one of those online gear ratio calculators to get an idea of the rpm difference for each ratio and see how much rpm drop you will see from one to the other. I use www.richmondgear.com to compare.
