Hi all - new to the forum, glad to be here, such a wealth of info!

2010 SS 5-speed, Brembo front brakes, 102K miles - got the dreaded LF wheel bearing growl, so went to replace the bearing, hoping I was going to be able to get it separated from the knuckle and save the "hub spacer" which GM no longer makes - anyone know where this spacer can be purchased? I've searched high and low through aftermarket, can't find. I am wondering if we can just use the brake shield that was the subject of the GM service bulletin for non-SS HHR's from 2006-2008 I believe? Would this shield act as the proper width spacer, or perhaps I could just cut it to fit if the "shield" portion somehow does not clear parts of the Brembo assembly?
I am not going to be able to save the original spacers because the hub is seized, and I mean seized, onto the knuckle - I'm just gonna replace the knuckle as well.
Thanks for any input!
Jim

 

I think the "spacer" you are talking about is the brake shield that you refer to. Not really a spacer its a watershield. It just sits between the hub and knuckle, I don't know how you could damage it unless you trying to pry.

Lots of your favorite corrosion fighter and a slide hammer should do it. If not take the knuckle off and press it out.

The hub spacer comes in this kit from ZZP, I don’t believe they sell them separately

...hmmm...I appear to be completely out of luck finding this spacer sold alone - I assume my only options are to have one made (anyone know the thickness?) or does anyone know if the brake shield from the non-SS non-Brembo brake could be fitted on the Brembo-equipped hub/knuckle? The spacing of the three mounting bolt holes should be the same I would think, so it would just be a matter of the thickness and the diameter of the piece.
Many thanks for such quick responses,

 

That shield is only a few thousands thick , you could measure your old spacer , apparently, they are 3mm thick

 

I'm not sure if I'll get the old spacers off intact but will try to measure them before removal of the hub, which I have to have someone else do - I tried several nights this week with PB Blaster, larger hammers, slide-hammer, etc. and no movement at all - I have in-and-out movement of the axle shaft so that's not seized, but the hub-to-knuckle surfaces must be fused.

I emailed ZZP to see if by any chance they'd sell me just the spacers - I made a plea to them!
