rear ajuster arm seized

[Philjwb]

I went to get my alignment done yesterday (Z4M roadster) and the garage said my rear adjuster arm is seized. They said they would have to cut it out and I would need a new arm and related ball joints. Trouble is I can't work out what parts they mean?

I've tried to work it out from the parts catalogue here:

From this I guess it is the eccentric bolt (10) that adjusts camber. I think the garage are asking me to get a new lower arm (5), but this isn't adjustable so I'm confused.

Could anyone explain which parts are used to adjust camber on toe on the rear wheels?

You're correct, it's 10 and 11 that adjust the rear camber.

I guess they're saying you also need a new number 3 and that they can't remove it without damaging number 5.

Should be able to just grind/cut the bolt out then press out the balljoint. So at worst a pair of balljoints (one for each side) and new nut and bolt.

I was not happy with the alignment work that I had done (at F1 in Chelmsford) for a number of reasons:

Steering wheel off by ~5 degrees
3 warning lights on dashboard came on which are related to the steering angle sensor and can occur after a bad alignment
Didn't trust the garage regarding the seized bolt

So I searched around for another company and found this great groupon deal at bubble and kick in Basildon for a 4 wheel alignment for £20:

It turns out this deal is for return to factory spec, but they only charged me an extra £25 to have it aligned to CSL geometry. The guys were very friendly and they did a great job - very close to the target values. No mention from them about any seized bolts, the warning lights have gone, the steering wheel is straight again and most importantly the balance of the car feels great

Happy to recommend this deal to others wanting an alignment!
