ok now that I've got my injector issue out of the way, the next thing is that I need new thrust arm bushings (and an alignment)

i would rather just replace the entire control arms as i've read that the thrust arm bushings that are bad are housed in the control arms themselves.

my 09 335i sedan has 127k on it and i'm thinking of upgrading to the M3 version considering I have to change them anyways.

I am planning on DIYing this as I've just successfully completed a bunch of other mechanical tasks and as long as I have step by step directions for this, I can do it.

if i replace everything I know what I need, but I'm thinking i'd like to just replace ONLY what is wrong currently and not spend the extra $$ right now.

which exact part numbers do i need ?
do i need the control arm that's bent AND the one that's straight ? or just one or the other ?

right now my car drives like crap suspension wise and i need this fixed ASAP b/c i just put new tires on the car and don't want them wearing wrong.

I need the same thing at 90k miles, I'm looking at doing the M3 control arms as well

if you have 127K and original bushings/arms, it's time to replace them all.
if you need to space out the replacements due to cost - do the thrust arm first.
Go to realoem.com, pelicanparts.com, etc. Put in your vehicle info and check what part # is listed - not rocket science.
check the actual condition of your bushings to see if they have too much flex, balljoints to see if they are leaking. Can't really go by just looking at them.
