for sure the lower control arm to strut bushing is already busted by now, why? because you don't tighten those bolts when the suspension is hanging in the air. It should be done with the load on or with the exact ride height. Ride height means when the tire (suspension) is level to the ground with the load of the car. He could just jack up the lower control arm until the suspension compresses (load heigh/ride height) and then tighten the bolt.
Sure you may be right , but I can tell you this on my personal gl450 I have done the complete suspension and it has been 3 year at least and no problems with any bushings ...
About to attempt this myself. I see the Mercedes WIS guidance document says, about refilling the air bags, "The wheels must not be in contact with the ground during the filling. Since the air suspension bellows in the spring element is destroyed when filling in deflected condition." Which sounds to me like its lost something in translation, but I do wonder if there's a real point there nonetheless?
Well if you have a message on the dash of malfunction or something in that area, after replacing the shock you will need to clear that message in order for the car go back and start pump air again, but as far as the shock replacing just do it like I didn't and when refilling the bag with air just lift the car a bit so that the weight its not on the bag.
Hello I have about 3 videos of the same job in one of them im sure ill say the stuff you need bit on the latest one ill have the best trick to how to get it out easier.
Hello there is only two types of shocks for them and that depending if it's a gl450 or gl550 this is the same process for the years 07-12 after that is a different strut/bag but the process to replace its the same. The job was about 2hr at the most , brand the customer got it from online so I'm saying he probably paid $1-200 for it.
Well it depends on your mechanic lol an oem strut from the dealership itself could be around $700 but online about $200 and labor from your mechanic depends on his rate but I wanna say if he has done this before should be a walk in the park ill say $4-600 part and labor should be ok
