Post Coupe Groan

On my car I had a complete front end alignment done, it drives *perfectly* but groans when I reverse direction and occasionally when I use the brakes .

It never makes noise when I depress the fender and the noise in only on the driver's side .

Hey guys! thanks for the replies!

mine has turned into more of a clunk and still happens occasionally when turning the car, usually off camber turns and also from stopped or nearly stopped acceleration and slowing down. This of course happens quite often sitting in morning and afternoon traffic each day

I did replace the rear engine stop mount on the car, definitely a neglected to replace part. new part MB part too!

Also just got new Mercedes-Benz wheel bearing kits so that will be this weekend.

see some pictures of the engine stop mount

German mechanic who put on the new front end suspension and steering components put the camber to near zero so wheels are straight up and down.

I then also paid firestone for their lifetime alignment. car does drive straight and true

Post Camber & Caster

Yes, those are critical details, I don't like too much caster either .

Too many roads these days are poorly re surfaced and have serious crowning, makes the vehicle want to drift but helps rain run off .

You'll have to watch Firestone. I have their Lifetime on several cars. I took my 85SD in after a complete front end rebuild. The tech gave gave it back with camber on both tires maxed out to one side sort of //. His note said "can't be aligned". He should have added "by him".

What happens is that changes in either caster or camber causes changes in the other and the tech has to anticipate the change to get setting correct. The FSM has approximate changes.

This guy turned on the machine, set camber then caster then toe. All had moved when he went back to check. He spent at least 2 hours chasing his tail.

The tech can bump the head of the lazer to make it look like specs are set correctly. Another shop demonstrated. The machine moves but not the wheels then they print the readout as final alignment settings and show the customer what a great job they did. No one knows the difference as long as the car steers reasonably well and doesn't wear tires (quickly). They could pass worn tires off as you hitting a curb after the alignment.
