Hello,
I have a problem with aligning the front end on our '95 W124 Cabrio. I put new (used) wheels and tires on the car going front 15" oem to 16" CLK wheels. (note: tires are the same diameter 25") After installing them the car pulls to the right constantly. Granted tires could be bad. However! The problem the shop had was they could not get the caster to +10 on either side. Only to +8. The toe was ok, camber slightly under. They looked over the suspension and did not see any "failed" parts. They alluded to worn struts or strut mounts.

I have searched the forum and learned of the spreader bar requirement for toe. I will check with the shop to find out if they used one. Would this affect caster? I wouldn't think so.
Is there a certain order the alignment process needs to be done?

We have only had the car a few months and this is the first alignment. the car did not pull before changing out the wheels and tires. I do not have previous alignment records to know if this is an old problem.

All ideas and help is greatly appreciated.

Thanks, Brian
