Looking on RA to buy rear axle bearings. How can I tell if the ring gear is 8.8 or 9.75. I have seen posts that said if the diff cover has 10 nuts its 8.8 but if it has 12 its the 9.97. I know there's a tag on the diff with codes, I'm hoping there's an easier way to tell than having to climb under the truck.
Get under and look.
Suppose your told wrong?
The truck had several options for size depending on model and build.
H9 is the ratio and open or limited slip ID.
Good luck.
