Suspension DIY Help
Hey guys,
Hoping someone can tell me the best way to release the lower rear arm, i am just trying to release the tension on it somehow,
Basically today i tried to replace the rear bushes (putting in adjustable ones for camber correction) anyways after 3 hours of mucking around i ended putting everything back.
Basically the lower arm was under a lot of preload and was thinking people that have replaced their airmatics would have a good way to release some stress from the lower arm before unbolting the airmatic shock ?
Any help appreciated. I then have to work out the best way to press out the old bush

The bushes came with a tool to press out the old bushes, or rather wind them out but i think the tool needs a little modifying to make it work properly.
The lower arm i have sitting on a gearbox hoist, while i work on the bush, but was thinking t would be great to get the gearbox hoist out of the way and people that have replaced shocks or airmatics would know whats the best way to get this arm off etc.

You need to release the tension on the lower control arm by letting the air out of the air spring. CAREFULY unscrew the hose from the top of the spring and CAREFULY insert a small thin screwdriver CAREFULY letting the air out of the valve. Did I say to do it CAREFULY?

Anyways I followed the line and unscrewed it on the otherside, where there seemed to be a bias valve (screwed to the backing of the right rear toe adjuster), and a little air came out but not much and the bags did not go down.
The line that goes into the rear shock goes into it from the side, unless there is another line that comes from the top (in which case this would probably be coming from the boot area).
I will try get some pics up shortly and see if im looking at the correct line.

just thought i would let anyone interested or anyone searching later on know that i found out the proper way to do it is to use the star diagnostic to release the air. basically solenoids inside it open and close so its not that easy to do manually i would think. If so i would think that you would have to power up the shocks some how to get the solenoids to open atleast one of the valves, from the diagrams i have seen when the solenoid is not powered (car parked) then the air remains in the unit.

probably atleast 3 wires as there are two solenoids, and knowing mercedes probably some sensors as well.
Thing is you would probably also need to know what voltage and amp to supply before doing it

You're probably right. 1 wire common the other 2 would be open / close to shuttle the solenoid. I would not expect more than 12 volts needed. but starting at 5 would be a conservative start as there are many 5 V regulator circuits
