W210 Alignment Woes

[c_ron]

I've shared this background before: My 96 E320 has 87k on the odometer, 37k of them mine. In that period I've gone through two sets of tires even though I've had two alignments.

Exasperated with the weird tire wear, not to mention the cost, I took the car to the local dealer this morning for an MB alignment.

They installed camber bolts on each side in front and have assured me the weird wear problems are now a thing of the past (Alignment: $120 + two camber bolts: 130 + tax = $270).

Now I'll put a new set of tires on the car tomorrow.

My questions are why would a well manufactured vehicle (I presumed when I bought it) require that these camber bolts be installed (at any cost) by the dealer in order to effect a proper alignment? And are these camber bolts really going to work?

All thoughts appreciated.
