Do you have knowledge of rear end gears??
If u google "auto zone part number 39028" it comes upwil it fit ???? 100%??

Is this a trick question? It says on the site it fits. Go to a local store and get it, if it is wrong, they can replace it with the correct parts.

Are the spider gears all that is damaged??

I have a 96' GMC Yukon 4x4 that may need a new front Differential soon. I have the GU6 Code in my Glovebox that says I have a 3.42 Ratio rear Axle. But it doesnt give a Code for the Front Axle, they should both be the same Ratio .........correct??

I have a 1999 Chevy Tahoe LS. Tires are 265/70/16. The sticker says i have a gt4 with a gear ratio of 3.73 . I was told when it was given to me it had a tow package. First, how can i check to see if it does have tow package and second, if it does do i need a higher gear ratio?

Yes. I just had the same question and was told definitely. My brother didnt and it tore up his transfer case!

What would I do if I don't have the sticker in my glovebox?

Get the build sheet from gm using your vin.

During business hours select: question about a vehicle I already own. Give them your VIN and ask for the RPO build sheet.

Thanks ... I'll do that here in a bit

Hate to resurrect a 6 mnth old thread but,my tahoe is in the shop for a rear end rebuild.It's a 2005 Ppv (ex trooper) tahoe,it has the gt4 g80 (3.73).What would be a good all around gear?I'm on the road alot and the 3.73 does Rev the engine a little more ,I rarely tow.How about the 3.42?Maybe 3.23??

3.08 with the 4-speed will be pretty slow and doggy. If the 3.73 is a little high for your liking, try either of those two, the 3.23 being better for cruising on the highway of course.

Hi, I have this, but no idea what gear I have
View attachment 253421 the truck is a tahoe k1500 diesel 1995

Update, found this, posi track and 3.73s, but I have 33s, it is a diesel, so, 4.56 will be bad?

 

[Awleyze]

hello is there any codes on the actual rear end itself?

 

[exp500]

Your diesel is rpm limited, with gas you get 6K rpm. Stay with 373's or drop 20 percent rpm to 308's but it will be really slow accelerating. I think you have around 170 HP.

Hello - I have a 1995 Tahoe LS 2D 4WD, with a OME gear ratio of 3.73, LT 265/75/16 tires, and I was thinking to change to 33" tires with either LT285/75 or LT255/85. I have 157,200 miles, and the truck runs great. I don't want to lose any power, so any thoughts about a gear ratio change with the larger tires would be appreciated! Thanks

unless your towing near capacity often i wouldnt bother, the expence would be greater than the benefit in most cases. unless your looking for better gears for more power (also lower milage) then i would just leave it.

one tire size like that really dont have too huge an effect. i have done that exact size swap on a couple trucks and only when pulling a trailer at or a little over capacity with my 5.3 for 150 miles did i notice the difference, and being i have made that exact trip with other loads it wasnt that noticeable.

you may however find greater issue getting them to fit without trimming on that bodystyle.
