The very local Pull-a-Part bone yard is getting quite an accumulation of HHRs that I going to peruse for salvage (there's a virtual mess of Cobalts too) before they drag the longest-on-site to the crusher.
My 2010 has some very nasty drum brake backing plates. If I-Spy some that aren't rusty-as-Hell, how hard is it likely to be to strip just the backing plates off of the rear axle?
Dismantling the drum brake hardware, and removing emergency brake cables is no mystery, but I'm in no hurry to take -mine- back apart to get a better idea as to what I'm getting into. Dragging home (and paying for) a rear axle just to get brake backing plates doesn't excite me either.
The R.A. site doesn't even offer backing plates that I've been able to discern, and the online parts catalog exploded diagrams aren't a genuine help either(hard to locate rr. axle & brakes illustration in the parts catalog pg.22 -nearly at the end). I see that the rear hub needs removed.
What would need to pass muster about the rear hubs to make them worth bringing home?
Some pointers, and maybe -needed tools list- to get the backing plates off of the axle would be appreciated, because spending the afternoon crouching in the stone-paved bone yard isn't anyone's idea of a great time.
I'd like to spend my best efforts pulling the leather driver's seat I've already discovered, and pulling a set of running boards from a terribly rusty donor are both going to be 'great times' , and it's just so hard to convince myself to go back for another go-round.
Finally, are any of the dozen-to-fifteen Cobalts going to share those same drum brake backing plates?
I'm really hoping to track down a trailer hitch (and maybe a rear sway bar) from among all the candidates out there too.
Hours, to half-an-afternoon spent in a junk yard salvaging reluctant parts surely is a recipe for headache and bloodied knuckles. Yikes !

 

You have to remove the wheel hubs .
2006 thru 2008 are different from the 2009 to 2011.

 

Would you speculate(or know) if any of those dozen+ Cobalt cars will share this design, and particular parts?

 

OR,
You can find a Cobalt TC and swap the whole rear beam to have disc brakes.
It's a bit more work but to me it was worth it.
That's what I did.
Now I have a 2LT with 4 wheel disc brakes.

 

Not sure, so I would not guess.
