Ring and Pinion install price?

I've seen some pinion depth gauge kits in the $100 range recently.

I'd spend the money on the kit and learn how to do it. That way if ever need to do another you have the skill, plus, if someone else needs one done, you can help out and teach them, maybe make some money to boot.

Had the same thing happen when my AC compressor blew on my truck. Places wanted 300+ to flush/recharge. I spent under $100 on tools/freon and did it myself. Now if i ever need to do it again, I have the tools and ability. 8)
