Rear upper control arms

[ONEMINUTESILENCE]

My vectra is banging at the rear when over uneven surfaces. It also has a "shopping trolley" effect where it feels unstable. I have been advised it may be the upper control arms. There is also a metallic rattle coming from the rear o/s. When I apply the brakes this stops so I am assuming it is a brake component??

The dealer wants £290 to change the UCArms, can anyone tell me exactly what parts I need so I can buy them myself & give this a go. i.e are there any bushes that will need changing at the same time?

The brake rattle sounds like a pad sliding about, I had the same problem and sourted it out by using bits of copper on either side so it couldn't move.(maybe somebody a little more technically minded can explain this better for you)

As for the upper control arms there is a how to on the forum but I found a nightmare of a job to do, however it was well worth it .

Tip, drop or remove your backbox gives far better access to the inner bolt.

tried this a couple of weeks ago and i couldnt get into the top bolt and they looked like new to me but did notice the hub carrier bush was away so just waiting on me mate getting back to me so i can use his ramps lol

I did mine at the weekend! easy job really, just need the right length extension and E18 socket. And i still had my springs etc in place :P

I was surprised tho, it's made a MASSIVE difference to the handling, and it wasn't even knocking, just a bit of wobbly side to side movement before on uneven surfaces, which is now completely gone, and the back feels amazingly tight lol

Well I managed to source the control arms for £55 (Vauxhall wanted £170!!! ) They are new however I think one of them may be used.

Here are pics of them both to compare. It's the one on the left that I dont think is up to scratch.

No way would I put that on my car that looks like it would last about 5 mins

They look shoddy and dangerous

I changed mine about 3 weeks ago, pretty simple job to do, just fiddley if your rolling round on the floor, I took the rear springs off to aid access but it's upto you which way you want to do it, I paid £26+ VAT for mine and there FAI ones you should be able to do them in a couple of hours

The arms are around £35 + vat from andrew pages, i did these on my old preface & the lasted the whole time i had the motor (a few years)
