Moding a c3 trailing arm to accept C4 hub bearing anyone done it?

[JeffP1167]

Just curious if it could be done

the real question is why, the trailing arm is the piece you want to eliminate

To eliminate the costly rebuilding of the bearing stuff.

I could bet my bearing redone my Gary for 500$, including parts. Dunno if you'd save anything with such grafting.

I dont think a c4 bearing is much more then 150.00 but it's the time and complications of rebuilding that would be eliminated verses just unbolting a c4 hub bearing and bolting a new one in.

It could be done. I've looked at it. The dowside it it would take some machine work to do and, as Marck said, you still have a trailing arm.

You can't polish a turd!

in my opinion, there's no benefit that justifies the effort.... the C3 bearings last a very long time if built correctly, I just did it and it's less than $500 in parts incl new spindles (my memory....)

now... if you already have all the parts then ... why not ??

I keep kicking around how to do just the opposite (C3 spindle in a C4 knuckle). The C3 spindle/bearing assembly seems to be bulletproof if assembled correctly, whereas there's no shortage of threads on Corvette websites regarding how often the C4 bearing assemblies fail when used a lot in competition or track days.

Regarding the OP, it doesn't seem like it would be that big of a deal to put C4 bearing assemblies in a C3 trailing arm. I had to make a custom bearing assembly holder for the C4 setup I put in the '69 (to make it easier to mount the Wilwood calipers), and a slightly different design should be possible to package into the C3 trailing arm.

My reasoning was, while I do have a complete front and rear 1990 suspension. I could do without the complete 90 rear suspension if that nice hub bearing could work. I rarely ever drive a car hard so the c4 rear suspension really isn't necessary. I just wanted the ease of bearing changes without the hassle of making all the C4 stuff fit.
