Wheel bearings

[aaronswink]

Please help. I have a 90 c1500 an I bought a 2-4 drop from rough country, I cannot find the correct inner wheel bearings for the spindle and brake rotor. Rough country is no help. I’m sure all you experts have dealt with this. What vehicle do I need to get inner wheel bearings for??

I thought all gmt400 where hub assembly?
Are we talking about the front?

A quick look on rockauto, I guess 2wd didn't have hub assembly, learn something new I guess.

But they list 2 different applications
Standard cab pickup without hd f44 option,
Or
Extended Cab pickup with f44 HD.

Here's a screenshot where they have measurements listed, if you have a caliper should be pretty easy to figure out

'88/90 C1500's use a smaller rotor & subsequently, a smaller stub for the spindles.
You could upgrade to the larger rotors, but that requires the appropriately larger spindles.
The bearings are different between the two.

Does the kit you bought come with new spindles? If the kit also fits extended Cab trucks, it probably has the upgraded spindle size?

Yes! Only the early RCSBs have the small rotors.
Excabs got the bigger ones.

So that means the op will need the larger rotors with his kit, correct?

O/P didn't post what body style his truck is nor what the rotor size is that's on there now, sooo...
Those early small rotors are the only diff when it comes to front end stuff over the 1/2 ton 2w.dr. 400 production.

No, 2wd 400's are serviceable bearing assys.
Yes, the front. Since the rear would be a solid axle and not affected by a lift or lowering kit.
