4x4 help, transfer case works, hubs don't - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Dr.Destructo · 06-09-2005, 10:16 AM

Hi;

As you can tell by my other posts, I am currently certifying a 1983 Chev Blazer 4x4 305ci

The 4x4 doesn't work. It has limited slip on front and rear.

The guy I bought the truck from (for $400) said that 4x4 worked, but when I jacked it up to investigate, I found that:

The transfer case engages no problem. However, the front wheels don't turn in 4x4.

I would imagine that this is a problem within the hubs.

Wondering if any of you can specifically mention which part may be broken that would stop the wheels from powering.

I have the service manual, but I want to research these problems before I start taking the hubs apart.

Thanks

Do you see the u-joints turning in the axles?

Dr.Destructo · 06-09-2005, 05:04 PM

Yes

Then if you locked the hubs and the wheels don't turn, you need new hubs.
Open them up and see what's going on inside.

Thanks guys. I asked this question on a few boards, so I got the same answer everywhere. Looks like new hubs are in order. Going to open them up this wknd...thanks again.

Like kwmech said.Put a set of manual hubs on.
