Hello,
My D4 just got new front lower arms, Meyle heavy duty, fitted with a new fitting kit. I had no problems fitting the arms but when doing the wheel alignment today they were not able to set the right side camber to within spec. Good, experienced company with Hunter equipment which I have used several times before. Camber is supposed to be -0.50 (+-0.75) and they could not get it closer than -1.42 so 0.17 from limit. Left side was no problem. Anyone who might have an idea why the camber can not be set and if it really matters? Car feels nice on the road but I don´t want extra tire wear.
Thanks,

Here are a few...........
I think the first place to start would be with the ride height as this would affect the camber figure.
At normal height it should be 465mm centre wheel arch to centre hub for the front.
Were tyre pressures correct, similar tread depth?
Was the vehicle in 'tight tolerance' mode, normal height, with the engine running while adjustments were made as this allows for height compensation as things adjust?
Having said all that if the vehicle drives/brakes straight and doesn't pull then I don't think I would worry unduly.

Yes, had this on mine after changing the front lower arms. Could not get the left camber correct. After this changed the rear upper arms and rear hub bushes. All set up fine after this.

Thanks for you suggestions. I did not check the ride heights before the alignment. Will do so tonight and calibrate if necessary. Car was in tight tolerance mode but engine was not on.

Checked the heights; all perfect.
I have today been to the alignment place and talked to the bloke in charge. I didn´t have the full picture yesterday. The original problem was that it was not possible to move the control arm at all as it was under heavy tension. The arm needs to go in in as it is to much negative camber. When they tried to adjust it using the bolts it didn´t move so finally the adjustment tabs started to spin on the bolts. They also tried pulling the arm in using ratchet tie downs but it didn´t move.
There is plenty of possible movement so it should be possible to adjust. I wonder if the cause could be that I tightened the bolt for the damper before jacking the arm up to the correct height to tighten the arm bolts and thus inducing tension in the spring/damper assembly? The plan now is that I will change both the bolts and set the arm to the innermost setting with the car on the lift. After that they will do another wheel alignment so hopefully it will get resolved.

Yes I would loosen it all off, get everything at the right height then retighten, otherwise bushes are under tension at normal height, something you don't want.
Good luck, sounds like you are nearly there.

New bolts fitted and damper bolt loosened and tightened at correct height. New wheel alignment yesterday and all is now ok.

All should be ok now but I can´t help not being fully satisfied... I have now been driving for a week after wheel alignment and I feel that the car is a bit "nervous" on the road. It is not really as stable as I would expect with new arms and steering rods when driving. It is not really bad but not better or even slightly worse than before changing the arms and rods. Looking at the protocol from the alignment there seems to be a target number and a +-range around it. As an example the target camber for front left is -0.15 degrees (+-0.75) and front right is -0.50 degrees (+-0.75). Car is LHD. So the camber can be set rather differently and still be within the "green" range. The same applies to caster and toe. Is there any general consensus how the alignment should be setup to work best for a Disco3+4? Spot on at the target values or would anything within the "green" range be ok?
Thanks,
