I would like to do this my self ,how much of a pain will it be and is there anything that I need to look out for? It's a 10bolt with the G80 posi.

I have the G80 in it but have a Auburn unit as well . Which one is better?
I will be going with a set of Richmond 4.10's to replace the 3.42's

Any info from anyone that has done this would be helpful.

replace it with the auburn. much better unit than the G80. i have a auburn in mine that is almost three years old and is still going strong

do you have all the tools to install it properly? if not dont do it. a ring and pinion install isnt something to dick around with.....

also if you havent done them before, I would hesitate on a DD unless I was sure I could do it. if your good with that then do it, just take your time and make sure that the pinion is seated correctly

Ya , not worried about getting in there and doing it just wanted some feed back from someone that has done it that could shed a bit of light on it .
I have a SSTrailblazer for back up if the truck is down for a day or two.

I did a gear change myself 2 yrs ago on my 2000. Here is a link to a write up I did on it including photos of the cantact patterns on the gears when I was setting them up. It took 2 tries to get the shims right. This is not a job for the timid or for those without access to tools and resources. Look at the link it'll give you a little insite into what you can run into.

Sell those Richmonds and buy OEM AAM gears from Ron @ Ron's Machining Service.

Great writeup, very informative and entertaining After reading that, I now have a craving for chili though lol

Did the gears yesterday, what a cake walk. The hardest part was just getting the C-clips out and back in.

Very happy with the results .
