my c300 frontend sqeaks or creaks when in full turns especially when drivign in
and out of driveway with drainage curb dip. v shaped dip. does anyone have a clue
what fault is. i checked car in full turn not moving by pushing car up and down from
left and right side. no squeaks there.

 

I would guess suspension bushings...

 

i understand. cr is a 2015 with 41k. havent located which one it could be
as et. thanks for your time.

 

Lube everything movable that you can get too...
I would use a ZEP45...

maybe bad ball joints. All the crap they have today is not grease able, designed to fail

 

I will have to try the Zep45. I have been using WD40 but it does not last long. Years ago a lube job included using a product called RuGluide on all bushings and Doorease on all door latches, I don't know if they sell that stuff anymore.

 

Those where the days of the good service programs. We had to lube everything...
