Hi I have an 1985 300D Tubo. When the upper front control arms are replaced. Do you need to have an alignment done.
Thanks in advance.

Mike, I can't imagine why it would be necessary as its not associated with the steering system. Now if you were messing with tie rod ends, an alignment would be needed for sure.

Not with the upper control arms.

Absolutely. The bushings in the UCA's sag with age and cause the camber go become increasingly negative. If the alignment was within reason before replacings the control arms, the camber is most likely to be excessively positive with the new arms installed.
