HD carrier bearing. The odd one.

I also have a leaf spring C10, but has the horseshoe style center support (like the one Corts60 bought.)

Next time I replace mine, I'm going with this one NATIONAL HB88532. It's 1.378" I.D. and was found on some trucks and vans from 1987 to 2006. Just another option to think about since this one seems heavy duty.

That looks legit. I’d like to know what the dimensions are from the mounting surface to center bore. I think the factory one is 3.4375 or so.

Great work.

I used the same Neapco bearing in my truck and it has been working great.

My original one the rubber had shrunk and it just rattled around in there in addition to the bearings being whacked.

Hopefully the info here will help other people find the replacement part rather than having to cobble together a different style mount.

How long ago did you get it and where did you source it?

So I looked up the specs and the centerline height from mounting surface to driveshaft centerline is 2.2". The factory HD centerline height is about 3 7/16 - 3 1/2". I think the bolt spacing is correct though. So if a 1.5" spacer plate was made, this would probably be a great choice to replace the factory HD bearing.

That's what I thought, a couple of days ago...

What if you flipped your mounting bracket and mounted the newer style driveshaft support so it was hanging down, how close would it be compared to where your driveshaft is now?

Another potential good idea???

However if his bracket is riveted to the crossmember (as all, I've seen, so far), that may be easier said than done...

[Corts60]

Well I got it all back together and went out for a test drive. Success! It is nice and smooth. I even through in a new u-joint at the trans slip joint. If I have to do this again, I will probably try flipping the bracket like you guys suggested. I didn't even look at that while I had it apart.

I hope this thread helps someone out in the future!

Awesome. I think I missed your final update on this back in the day. Just wanted to add that this is what is so great about the message boards and the ability to find this info at a later date or even on a search engine and why the Facebook groups are just NOT a good place for tech.
