Why are there so many different parts that show up that are vehicle specific to my 08 hhr ss automatic? It stresses me out nothing can just give one freaking part number and be done with it. I need to replace my passenger rear wheel bearing. Can anyone please tell me what gm/acdelco part # I need?!

 

Did you look in the Commonly Used Parts thread ? It's in there.

I did not! Thank you so much 😊

 

Do yourself a favor and replace both sides.
Personally, I used Timken from Rockauto.
Don't forget the discount
ALL rear hubs are the same LS, 1LT, 2LT, SS

Are you sure about that? The GM parts book lists different part numbers for SS, and a $79 price difference.
2009 SS w ABS $279 ea.
GM 20907864
AC/Delco RW20-138

2009 LT/LS w ABS $200 ea.
GM 15889806
AC/Delco RW20-107

 

The link I posted was for an SS
