New arms or just replace the bushings?
Ok, already got my one question answered in the engine forum and am hoping to get an answer to another question in this forum.
Took my car to the dealer to have some scheduled maintenance done. When I got the work order back they listed some other items that should be done. One of those items was the thrust rod bushings (tension strut?). I am wondering if I can just replace the leaking hydrobearings with the Powerflex urethane bushings ($100) OR should I replace both arms ($230)?? My car has 67k miles on it. Thanks in advance.

Lemforder and Meyle make replacement bushings as well. I wouldn't use urethane bushings.

Why not urethane? I always thought those were better than rubber.

Meyle also makes the "HD" replacement bushing. Has anyone tried that yet? We've all got M3 arms it seems like...

'AlanAZ' replaced his tension arms w/Meyle HD arms; says he likes them and didn't want to go M3

Does anyone know the part number for the rubber bushings? I found the part number for the Hydrobearings (the one's currently leaking on my car).

What exactly are you looking for? The hydrobearing you found is the replaceable bushing on the tension strut (31126763719).

I know, but are they the same as the thrust rod bushing? I mean is the hydrobearing and the thrust rod bushing the same thing?

None of the other joints in front appear to be replaceable.

^^ With that in mind do I just replace the bushings then? No one has really said one way or the other. Also I never got a clear understanding of why not to use the Powerflex urethane bushings except that they wear out faster.
UPDATE: I talked to Max at OEM Bimmer Parts and he stated to replace the arms since the ball joints wear at almost the same rate at the bushings. I can go to the Meyle HD arms for about $200.

Or, you could buy used original arms for cheap. I'd be happy to sell you mine if you like. They have a few thousand miles on them, around 5K. They still might even have some of that new control arm smell...

How much for your like new tension rods? I have about 85k on mine. They were off the car briefly while I had M3 arms that I found to be way to stiff.

I may replace the other arms at some point. I started antoher thread to try and find out the benefit of the BMW M3 versus the Meyle HD arms are.
