2002 tahoe rear differential cover size

[driven_mad]

I did a few searches with not much luck..

Can anyone tell me what the rear differential cover size is for a 2002 Tahoe LT 4x4 5.3?

thanks in advance

What do you mean by size? It’s not like we can say it’s 5”x 7” or 9” diameter, it’s an irregular shape. And don’t forget there’s a panhard bar right behind it so a deep one isn’t possible without mods. You need one designed specifically for your vehicle, not just for a GM 10 bolt rear end.

I realize that that's why I specifically said which vehicle I have

Perhaps I should have asked what size rear differential does my truck have so that I can order the proper differential cover. I will probably just look up the RPO code tomorrow but I thought someone may have some insight that has got through this already

I do know them rearends look small to be 4:10 on my 2006 Yukon XL . But they must of changed pinion size so ring didn't have to be so big .. you should see how big the rearend is on 1992 P30 Motorhome 4:88 rearend it's massive.

You’ll find it listed as a 10-bolt GM rear end but like I said not all 10-bolt covers will fit your truck due to the Panhard bar. You need to find one listed for a 2002 Tahoe with a 10-bolt. Check the number of bolts to verify. It’s not a size thing except for the depth. When you’re counting the bolts look at the clearance between the cover and the pan hard bar and you’ll see what I mean.

You have an 8.6 10-Bolt GM corporate rear differential. The cover is the same size used on the earlier 8.5" GM 10-Bolt axles too, like the Buick Grand National.

If you plan to replace any of the bolts, know what they are as the type and length changed over the years.

12 Bolt? I thought they quit using those in '91?

There are two 14 bolt rears, a 9.5" semi-floater and the full floating 11.5" used in the 3/4-ton trucks. The semi-floater is used in the 1/2-tons under certain circumstances.
