Need advice on rear end.

[Astro]

Pretty sure mine isn't the 8.5".

I guess I gotta do some research on making it an locker. I don't know much about how to convert them. If you guys have an threads to point me to or advice, I'd appreciate it. I'll look either way. I definitely don't want things blowing up on me.

Take a pic of the backside of the rear end?

Will do. I'll get back to you with it today.

96 k1500 today and noticed there's some axial play in the axles... ...It's a 14 bolt

Pretty sure mine isn't the 8.5".

Yup, not an 8.5.

Perfect candidate for rebuilding what's in there, as the 14-bolt axles are decently robust, or strong as heck, depending on whether it's a 9.5" or a 10.5".

Or--as said--stuff an aftermarket limited-slip or locker in place and enjoy.

Fairly certain it's a 9.5, but dang it if I remember how I verified that haha. I gotta get a parts list together.

Just count the bolts on the cover. This is a 9.5” 14 bolt cover.

If it has a 14-bolt cover AND has axle shafts that can be moved in-and-out, it's a 9.5" axle assembly.

A 14-bolt cover and axle shafts externally bolted to the hubs--a full-floating axle--would be a 10.5" axle assembly, and unlikely to be under a 1500-series truck. It'd also have 8-lug wheels.

Yeah, that's what it is for sure.
