SS Lower ball joint replacement
I attended the PRI show in Indianapolis, the show is more oriented to performance parts.
Chevrolet had a big display there for their performance division. I figured what the heck, I'll ask them about the ball joint for the HHR SS. Two different reps couldn't come up with a reason for this not being a separate item for purchase, or where they come from.
I also talked to a suspension specialist, and I use the term loosely, he showed me their listings for lower ball joints, which all had specs on the nub, unfortunately they where all tapered, doh. Then he suggested building a custom lower control arm...........I don't think he heard the part about the nub being a straight barrel with a relief for a capture bolt. So with his plan, now I'd have to source a different steering hub to fit the ball joint, this was starting to sound like a snowball rolling down hill. I can just imagine the domino effect on parts to get everything to work together.
I left the show with no usable alternative, which really didn't surprise me, so the quest continues. I will find the Holy Grail eventually, LOL.

Help
Ok I have read through this entire thread and just want to clear up a few things. Are the lower ball joints two different sizes or are they both 20.5mm? I purchased some Mevotech control arms that said they were for my FE5 suspension and while the car feels more stable I still get a bit of a clunk and the wheels wobble just a little bit. I have been working with a GM mechanic and he said the ball joints are the wrong size so I am assuming the control Arms I purchased have the 20mm joints on them which is causing my symptoms. I was hoping to just be able to swap those out but it looks like that may not be possible.
Here are the parts I ordered and installed
MEVOTECH CMS50174
MEVOTECH CMS50173
Do I have to get all new Control Arms again?

Yes you have the wrong ball joint.
tye only source for SS ball joints are included with the GM parts

an excerpt from the common part number thread
Lower Control Arm - SS models ONLY (FE5 suspension)
IMPORTANT: they are only available thru GM - No after-market suppliers make a compatible part at this time, even though they may say the parts they have are for all HHR's
- GM - P/N: 25930724 - Right
- GM - P/N: 25930725 - Left
(note: Do NOT substitute a FE1 or FE3 LCA - the ball joint stub on them is 20MM and is not compatible with the spindle on a FE5/SS which is 20.5MM)
order the new new ones now, before you damage the steering knuckles

Thank you for this information. My HHR SS is a 2008. Those part numbers say they are not compatible with my HHR. Should that matter?
Sorry to be a pain but I already paid for aftermarket parts that said they would be right so I want to make sure I get the right parts before I spend money again. If I look up my HHR SS at a parts place like GMPartsDirect.com I get these part numbers for the control arm
15803767 - Lower Control Arm Right
15803766 - Lower Control Arm Left
In fact it is those part numbers I referenced to get the after market ones. Seems those are incorrect?
IDescription: Without soft ride suspension. Fe5 suspension, without SS. With SS model. Cobalt. Left. Perf. & handling susp.
The correct https://www.gmpartsdirect.com/oem-pa...l-arm-25930724
All of the parts books are "confused"; There are 2 different models of Cobalt SS and 1 HHR SS, everybody ASSuMEs that Cobalt and HHR are identical.
The numbers Oldblue posted are correct from experience.
Cobalt FE5 Lower Control Arm Rh 2008 - 2010 25930724

those 15803766 and 15803767 are for the 2005 -2007 Cobalt SC they had the small ball joints , it’s a common occurrence. I believe due to wanting to save a few bucks because they are a bit cheaper.
