    Rated 4 out of 5 by from Great tool! I've used this to set the pinion depth on a fresh set of gears and it works well. The difficult part was determining the offset of the carrier due to machining. Once I got that figured, it was pretty straight forward. Read through the instructions before you start so that you understand what's going on. When I was finished, the depth was spot on. Literally excatly what was etched in the pinion! Measuring the backlash was easier than using a magnetic base.

    Rated 2 out of 5 by from Instructions that come with the tool are extremely vague, and leave alot to be desired.

    Rated 1 out of 5 by from You can spend a bit more and get a way better tool Instructions and photos are not user friendly and you have a lot of extra steps to find your measurement. Do not recommend.

    Rated 1 out of 5 by from Couldn't use the pinion depth tool I bought because the company I bought my ring and pinion from don't engrave the depth on their gears anymore so I just had to wing it. I was going to return it to Jegs and it was going to cost me half of what I paid for it so its sitting in my shop.After inspecting the tool ,wasn't what I expected.

    It appears this tool does not have a magnetic base. How would you mount to housing to check backlash? Working on a GM 10 bolt 8.6".

    Asked by: rat on
    This tool is not made to check the backlash of the rear end.
