AXLE identification - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey,
I believe is a gm 10- bolt rear on an 85 k10 but when replacing my axle seal the part listed at the auto dealer parts store was too small. On the side of the axle the number
TUM G291 and GM 34
I assume it is an aftermarket axle on the truck. It has a spool in it as well but that is besides the point. Any help w/ these numbers would be great.

Thanks Chad

easier with a pic or description of the shape and diff cover. Semifloating, full, c-clip? A 10 bolt would be stock, but you would be almost insane to spool one!

Ill try to get a pic tomorrow. Thought maybe the id numbers might mean something more. It's not stock because none of the stock seals work on it. I know it would be crazy to run a spool on a stock 10 bolt w/ 35's. Anyone else any idea's w/ those numbers. btw bought it this way planning to change rear end but changing seal in the mean time.

Thanks Chad

how many bolts on the diff cover? Might be a Dana 44 or corp 12 bolt??

chadbork84k10 · 11-11-2006, 09:14 PM

10 bolts on diff cover.

magnethead · 11-11-2006, 09:38 PM

Surely it's not a hybrid axle..there'd be no use for a hybrid 10 bolt.

Picture will help

chadbork84k10 · 11-11-2006, 09:50 PM

It's the gm 10 bolt, but dont understand why none of the seals for the 10 bolt work? ANY suggestions? Its def a 10 bolt.

Thanks Chad

yup, it has tabs, so there's no question it's a 10 bolt centersection.

Thinking out loud here and highly unlikely- might it have 9 inch or dana 44 (even 30/35) outers?

did you try taking the old seals to the store and opening every box until you find a match?

chadbork84k10 · 11-11-2006, 10:04 PM

Did that and got one and it snaps in but they couldnt tell me what the seal was designed for. I hope it works? Just trying to get the right seal so i Wont have issues w/ it and or need further parts..

Thanks for the input, dunno if a pic of the input would help or not?
Thanks Chad

You sure the parts place even has the right part number? You could try going to a different store and see what they give you.
