Question Refresh My Steering/Suspension Bushings

Hey guys.... i bought my 06 cobalt from an old lady 3 years ago. At the time i realized it would need suspension work and tires.. the usual. I upgraded to the fe5 shocks/struts and bought some used ss/tc springs. Aside from that and some new tires i havent touched the suspension. For the past little while the car has been all over the road, almost a pain in the ass to keep going straight (she pulls to the right). so obviously i know something is wrong... either just an alignment issue or worn out bushings. I had the alignment checked and apparently it was within spec. Shes got about 55k miles on her and i think its time to freshen her up. i want to replace as many bushings as possible and basically decided to buy new lower control arms, Tie rods (both ends) and sway bar links.

The issue im running into now is which control arms to go with. Rock auto has 3 different Moog models to choose from.

1: Moog - RK620301/RK620302 - http://www.amazon.com/Moog-RK620301-Control-Joint-Assembly/dp/B007ZLLLGY
2: Moog - CK620301/CK620302 - http://www.amazon.com/Moog-CK620301-Control-Ball-Joint/dp/compatibility-chart/B009B41CRG
3: Moog - RK620897/RK620898 - MOOG MOOG-RK620897 Front Lower Control Arm and Ball Joint - Passenger Side Made by MOOG

1 and 2 both say "with soft ride suspension" and 3 says "for performance suspension: fe3".

My question is: Is there any difference in the material of the bushings in any of these? Any input on which of the 3 i should buy?

The third one is cast alloy instead of stamped steel. Don't think you'll see a difference in the ride. But if you swap the pancake bushing for a MOOG problem solver K200792 then you might feel a stiffer suspension.

Don't forget your inner tie-rods.

The CK620301/CK620302 model is called the "problem solver"... is it safe to assume it has the problem solver pancake bushing that you mentioned?


Coby7... FYI... you came to my rescue a couple years ago when i was installing my head unit and needed help with wiring to find a contant power.

Picture doesn't show that it has the problem solver bushing but it might be a generic photo. I would inform myself before purchase.

I went all moog with mine. If you do the control arm bushings you may need a press.. or a big hammer to get them out. We went with the stiff ones to accommodate the pedders springs. Not sure if it made a difference since I did bushings shocks struts n tires all in one day
