Thanks for your response
Brand of shocks: Front shocks were replaced by my mechanic, he ordered them directly from MB dealership.
Rear shocks I bought myself from MB dealership with my VIN number, so both sets are original MB replacements, but I do not know the names.
TYRES are Michelin Energy MXV4 Plus V97 225 60 16
I have not checked the tire pressures cold, but I can do that 1st thing in the morning to confirm.
My mechanic recommended a car shop that has the equipment to do MB alignment, and that is where I had it done. I have gone back to complain that the steering wheel is still of centre, and I was told to bring it back. I will by the weekend.
Do you know if 300SE uses struts as well as schocks, or could the springs be weak?
