They replaced my 2 carrier bearings, pinion seal, and both axle seal. Also replaced both pinion bearings, and crush sleeve. Was 1,100 dollars . 6 hours of labor they charged. I guess that was diagnosis, fix, and test drive.
Anyway it is crazy how quiet it is now. I didn’t realize how much noise it’s been making for a long time. Pretty happy with it. Now if only I could get rid of the lil bit of gear whine I got. Damn 3:73 gears! Lol
Glad you got rid of most of the noise...that can be so annoying! As for the 3:73 whine/whir....seems that's the trade off on having them vs. stock gears. I have the same on mine....and I know others here have commented about it as well.
