And that's no Bueno on the axles. I'm guessing I'm going to need some at some point. We have no intentions on giving up our SS.
You can still get the pistons & rebuild kits.
HHR SS piston = 55mm, vs standard piston = 60mm , (may not be the exact numbers).
I use Centric parts.
front rebuild kit = 143.91016
rear rebuild kit = 143.62043
Centric front caliper piston for HHR SS = 146.54064
Centric rear caliper piston for HHR SS = 146.38038
Today I finally bit-the-bullet & ordered a spare half-shaft,
just in case, as I may need one someday, as I run with slicks at the track.
This part is on national back order, & i just hope that they will build more.
If this part does get cancelled, because GM decided that it's not worth it to build them anymore,
I can take my broken one to a good local driveshaft shop to be rebuild, it will mean 'downtime', with my 'buggy' on 'jack-stands' ,
waiting probaby a week for the repaired unit.
Been there, done that, with other car, & don't want to do that again.
