thrust arms

thejackyltm · 06-21-2013, 05:05 PM

question..dealership said my thrust arms need replacing. they wanted 350 to do it. is this something i can do myself? and also, read that you can use the m3 ones instead which id much rather do. is this al true anyone know?

You can do it yourself and use the M3 ones. What problem are you having and how do they know it's the control arms for sure?

You will also need an alignment after the work is done.

Was there a symptom to those going bad?

thejackyltm · 06-21-2013, 11:24 PM

the dealer said they didn't need to be done right away wasnt bad. But, he said ill probably notice some steering wheel shaking etc. and i have been but I blamed it on my new wheels and tires being the culprit. he said the rubber part is going bad on the drivers side, and i have the extra cash now so i figure might as well try and get it done if need be. is it difficult to change?

I haven't changed mine but I've looked into it. It looks like an hour or so per side for the average DIY'er. Puller is about the most specialized tool you will need and those can be borrowed at a local parts store.

Just buy the entire thrust arm and just swap it out. .. you just have to uninstall the tire and gender liner then un bolt and replace. ..very simple

M3 arms preferred for lightness, stiffness; Delrin instead o'rubber. A few photos HERE

If using M3 parts, dimension may be somewhat diff, a good thing. Do the wishbones too, and always do in left/right pairs. HPAutowerks a good source.

Always align after suspension work!

.

And while you're in there, M3 sway [anti roll bar] wouldn't hurt.

Is there a good reason to replace the entire arm as opposed to just the bushing?

Thanks for your help in advance.

Yes, as you also get a new ball joint that's at the other end of the arm for not much more money. I just replaced my arms with the Meyle HD brand when one of my bushings leaked out.
