Rear Suspension Squeak - e92 now sounds like a clown car

Just polling the group here to see if this is something you guys have experienced.

Over the past few weeks the rear has developed an annoying suspension squeak - I mean it turns people's heads when you drive down the street and are hitting uneven pavement.
Coming from the driver's side rear wheel and sounds very much like this:




I know, it's funny noise and you can make all the jokes you want, but it's pretty annoying. So has anyone experienced it or successfully fixed it?

The research says it's control arm bushings, but funny enough my regular mechanic didn't seem interested in taking on the work and pointed me toward the dealer. Would like to avoid the cost that comes along with that proposition - can anyone recommend any good indy shops in Brooklyn, NY?

Or since this looks like a 60 dollar part, is it something that can be easily DYI'ed? (I don't really have access to a garage or proper tools, so not sure what would be cheaper in the end, plus the risk of messing with the suspension when you don't really know what you're doing)


Thank in advance for any advice!

Ilya

Control arm bushing? Easy R&R! You'll need an alignment after, however.

But are you sure? Have you had it on a lift? How's the shock performing?

Well I can't be 100% sure, because I wasn't at the shop when they lifted it. But that's what the mechanic told me it was afterwards. That's why I was a bit surprised as to why he didn't want to get involved on the work. Could've been a 150-200 job for him. Maybe, since he's a friend, he didn't want to get into chasing the noise for a low quote if it wasn't the bushings after-all.

Shock performs just fine. Haven't noticed the car behaving strangely at all.

Hi....I realise this is an old post. but the noise you described is exactly what has just happened to my 2011 323i. it literally came overnight. Squeak is coming from passenger side rear. Did you find out what the problem was? Seems like control arm.

I'm certain I have sway bar bushing creak....had the temerity to silicone 'em on install so'd they turn easy on the bar. Months later, the squeak began....not evident in cold weather....sounds like a clown horn in hot, yup....maybe should silicone'em again?

I would check sway bar bushings and bump stops first.

Then ball joints. And finally control arm bushings.

Thank You...but I think I have to eliminate sway bar busing links. I was underneath today and stuck a pry bar through lower part of spring and control arm and the noise was mimicked perfectly.

Can't help but think it is either control arm or spring related.
