Per the subject line, has anyone used these? Are they(stamped steel) the same geometry as the cast aluminum arms? Any handling improvement noticed?

 

The steel control arms have never been recommended on this site.

 

The Moog PART NUMBER: MOOG-RK620897 and RK620898
are the ones to order

I used them, they are nice.

 

I prefer to rebuild existing LCA’s with

2

Front Lower Ball Joint

PART NUMBER: MOOG-K80567

and 2

Front Lower Rearward Control Arm Bushing

PART NUMBER: MOOG-K201285

 

HHR was never designed for the steel control arms, no version of the HHR was ever produced with steel control arms.... Should be enough of a clue to not use the steel control arms on an HHR.

 

How long ago did you install them?

 

Any shop i have contacted refuse to do bushing replacements on those control arms. They want to use new control arms.

 

They are scaredy cats! Some idiots are afraid to use a press on Al alloy; that is why there is a tool made for the job; basically a piece of all thread with a cup on one end and a press out on the other.

If it is the unlike metal thing they fear Moog makes one with the proper coating for alloy.

 

Why do they refuse? Don’t have a press ?
I posted the Problemsolver bushing with the zinc coating part number.
