Rear suspension stripping?
So I’ve got an unbearable squeak when driving. Had it into two different garages who can’t fully diagnose it, but one said it seems to be a wishbone shaped link, although there’s no play and it’s absolutely fine.
I’ve been looking for some links which will help me strip the rear suspension part by part but can’t find anything, does anybody have any handy websites or links that could help?
Thanks in advance!

A squeak is hard to narrow down, but the common parts in the rear suspension that wear out often are the anti-roll bar bushes, the ARB's droplinks and the outer bush in the upper control arm (the banana shaped one). Plus the usual bits, i.e. springs and shocks.

It stopped the squeaks because it now has some lube other than road dirt but the bearings will be worn and you should have a look at the wear on the tyres being caused by the wear on the bushes. The bushes are cheaper to replace than the tyres AND with the new bushes installed you will find there is less tyre noise as i did.

Try leaving the missus at home and see if it stops

Thanks for the replies guys!
I’ve spent two days spraying different parts of the rear suspension. Think I might have narrowed it down to the upper control arm bush furthest from the tyre. It lessened the squeak and made it go for around ten seconds but then it comes back, gonna get a proper jack and a fresh can of wd40 and see if tomorrow is any better!

If the culprit is indeed the control arm outer bush then noise won't be the only symptom, the rear wheel will have too much negative camber which in time will cause the tyre to wear excessively on the inside edge in a rough way, as if someone has been cutting the tyre with a hatchet. That wear pattern then starts to generate a droning noise when you drive that will have you thinking you've got a worn rear wheel bearing.

I’ll check out that tyre when I’m next in the garage and if it is worn then we have our culprit!

FIXED. Thanks everyone for their input, in case anybody else is going out of their mind with the same issue, it was the bushes where the anti roll bar meets behind the wheel, there’s a little metal part with two bushes.
Now to learn how to service the vectra. It’s easy this car malarkey thing
