Hi All,

Im getting ready to replace my torque strut "control arms" on my W211. My question is, will replacing them throw the car out of alignment? I plan on replacing the arms with the suspension compressed (wheels on the car).

This is what i'll be buying/replacing.

Have the toe reset after installing the torque (aka thrust) arms. And ensure they keep your steering wheel straight.

Front and rear, the only adjustment easily performed is the toe. On the front, you can install "eccentric" bolts (which are not actually eccentric, just slotted). Depending upon orientation of the slot, you can add/subtract 0.3 degrees of camber (and modify caster, of course). For greater adjustment range, there are KMac bushings.

On the rear, for non-AMG E-class, there is an aftermarket kit by SPC that allows you to modify camber.

How would i ensure that the toe is resets? I'll be rolling onto Rhino ramps, and change the arms that way.

You'll have to take it to an alignment shop. Alternatively, you set up strings and do it yourself. If toe is even 1mm outside the recommended range you're going to chew through tires in just a few thousand miles.

1/2 turn of a tie-rod end is approximately 3mm change in toe so a little bit goes a long way. On mine, I keep toe between 1/2 and 3/4mm in on each side.

So i had alignment done recently.

I guess my question is: If i replace the torque arms with the suspension compressed, it will be thrown out of alignment?

If you replace the torque arms, get the toe checked. Even a 1mm difference in the toe arms' length between old and new due to the bushings or ball joints will affect the toe.
