Should be a 7.5 (3:73/GT4) the 14 bolt cover usually houses the 8.5. So, depending on the size of the cover, you should be able to make a determination of the size of the ring gear. Please rate my assistance and leave a testimonial. BTW just because Car-Part.com

How to install a new rear axle in a 02 gmc sierra 1500


Jack it up ,pull the wheel on the bad axle side,remove the diff. cover,
remove the small pin holding the large pin in,slide the big pin out ,push the axle in from the wheel end,remove the c-clip in the axle and slide it out.
Would be wise to change the seal at the end af the axle tube at the same time. Slide the new axle in ,put the c-clip in the axle ,push it back in the carrier and reinstall the large pin and keeper pin,"Right Stuff" sealer makes a good cover gasket,3/8 drive for the fill plug,some gear iol and you're done,,not a bad job,no special tools required.

Replace rear axel bearing on 4x4 5.3 Litre gas engine


Loosen differential cover and let oil drain. Remove cover, remove U lock from axel. Pull axel out. Remove bearing seal then bearing. Install new bearing, seal and reinstall axel. Reinstall U lock and new cover gasket. Fill with 75-90wt gear oil. Now I know that sound pretty straight forward. But there are some things to remember. The U lock can be difficult to remove sometimes. The most important thing is the seal, you will need to make sure it gets seated correctly and not torn when installing axel.
