Squeaky Suspension

[KnockinShop]

Hi,
Yesterday I noticed for the first time that my rear suspension is really squeaky. I hadn't noticed anything before.
It sounds like a really old spring bed under my car! I believe it is rear suspension, but not too sure. Haven't noticed anything under there.
Anyone have any ideas, or experienced anything similar?
2005 530d E60.

Thanks,
Ross.

I checked the struts and no sign of oil residue.
Possibly the bushings but I haven't seen anything obvious yet. I need to get my car higher so I can have a better look!
I have figured out the creaking is coming from the rear passenger (left) side. Possibly around the control arm area.
Will get a better look to see if I can find it.

Looks like that's it.
Visible oil beside the ball joint. So looks like it needs replacing.
Thanks.

Have the same on my 2004 E61 - Bird's mending tomorrow so will let you know the cost if interested.

Thanks Giles, that would be great.

I got my rear ball joints replaced yesterday.
£70 for parts and £110 for labour, so £180 for both sides.
It is a common issue, and can happen more when the weather dries out a bit like it just has in Ireland, and the rubber and lubricant dries out.

Apologies for not coming back to you on this - had the same done and then went on holiday.

Cost was very similar and car now not embarassing!
