Poly bushings

[1100russ]

Newbie here. Been lurking for a bit since I picked up an 02 X5 from my boss for 500 bucks. 4.4 with 145k miles. Replaced the right front lower control arm (cheap from rockauto), a drivers door carrier (febi-bil from I can't remember where) and got a used seat controller because the steering wheel will not adjust (used,fleabay) but I have not installed that yet. Most of the info came from this forum except I purchased the cheap control arm before really digging in lol.

What I would like to know is where are you getting your poly suspension bushings from? I need to replace both thrust arm bushings and want to go poly after reading about the fluid filled oem type.

Also a question..... Like I said I replaced the right side control arm with a cheapy. It's been great for about a month. Had tires put on it Saturday. Drove it to work Monday and I hear a clunk pulling out of a parking space. Think it feels a little funky turning to the right but nothing extreme. I notice after the sun comes up that my front wheels are cambered out at the bottom. They were straight and true before the tire install/clunking sound. Also when driving home I get the dreaded wheel shake under braking that I thought I fixed with the control arm replacement. I will be checking both sides components tonight after work as well as the torque on the nuts/bolts attaching them but what would cause the wheels to tow out like that? I would understand if the lower control arm ball joints were bad but I know one is good. It might not last long but I'm sure it hasn't failed in less than 2k miles lol. I'm hoping I find out more tonight when I look at it but this has me scratching my head a little.

A little background, I've been wrenching on things since I was a kid. Used to be SAE certified (lapsed). First BMW was (is) an 02 330i (e46). Built a few Ford v8's with some hp. Now I road race an old bike (Honda 900f) that I built. I know my way around a set of tools but by no means know it all lol.

Thanks.
