I'm looking at replacing my lower control arms finally (70k, i've owned since 40k and no issues), as they are starting to knock. I've been reading about a "newer" design for the LCA being a thicker diameter bushing and or using RRS arms. Can anyone tell me if they are different part #s, or are all the LR028245(249) the "updated" LR3 LCA... and if the RRS are still "better" (stiffer), or the bushing diameter for the RRS?

 

I may be wrong but thought I saw solid urethane bushings ? Maybe ab?

 

There are Polybushes, yes....but the reviews on them are mixed.

 

I agree on the mixed reviews, definitely you do not want the red. They finally have the other two grades, one being close to factory, might be worth a shot. Available from lucky8 I believe. The company is highly unresponsive.

The factory ones that are upgraded are more along the lines of the ball joint is larger / heavier duty. Part number for those is LR028245 right and LR028249 left.

I don't like non-OEM ones, often made in China.
