confused Wheel alaignment specs for AU2 with IRS

Today I had the wheel alignment adjusted on my 2001 Fairlane with IRS. While the rear wheel Toe-in was adjusted to factory specs (according to the computer), the rear wheel camber was outside specs on both wheels but could not be adjusted.

Question ...Is there any way of adjusting the rear wheel camber ie shims?
What are the factory specs for rear wheel alignment?

The wheel aligner told me that the series 1 Au's were not adjustable but the series 2 and 3 were adjustable.

Can't help you with this, but the answers should be interesting given what happened on the previous wheel alignment thread!

Also, My understanding is that the IRS on series 1, 2 & 3 are identical. Anyone able to confirm this?

Thumbs up

Russ many thanks for the this very valuable information. As my Fairlane has Tickford 17inch wheels as standard, I will use the T Series specs for 17 inch wheel models.

I have re-read the previous thread on wheel alignments and dont wish to reignite the issue. However is it possible to alter Camber on the rear wheels?
Many Thanks

I cannot see any reason why not with either shims or a camber kit.
Cheers

Cut n Paste from another forum but may rovide assistance.

"Well guys after many questions and $50 poorer I finally got what I need to align the IRS on the AU. Ford put in their premium, some 1998 XR6's and special order lower spec falcon's a non adjstable bolt and washer for the upper control arms. No good if you lower the suspension.
Why $50 poorer for no reason well here is the problem ford list,s
P/N w-520214-s60 nut
P/N er-5b751-f cam washer
P/N er-5617-h bolt

As being in kit P/N ER5K500AKT which by the way is the correct part you need to align the IRS. only the bloody nut is the same.
But as i had already had fitted it they would not give me a refound even though it was listed by ford on thier parts cat wrongly . The part salesperson ( order taker ) said I should have orded the kit . I informed the F@#* idiot that his service adviser and him where f@#* wit"s and the local tyre power bloke knew more about fords than they do. His manager to calm me down gave me the 2 kits for the price of one at trade price.
I,am now a happy cappy as I,am posting this to let you know that only order the kit not the parts that are listed by ford."
