I have been through some discussion on this board re: alignment and have been told that the dealership is the only one that can do it. They charge me $150 each time and want to start replacing every part 'to make it right." I just had it done second time about 3 mos ago.

This is a commuter car and only gets like 4k miles/year. I know tire wear could be a risk, but if I pull the old part with the wheels on the ground, size up the new part (checking for centering in the socket as best I can), will I be that far off?

I realize I am bucking the "best practice" here, but my local MB dealer is a bit of a ripoff. Thank you for your help!
