I am starting this new thread as I am at a loss to find a solution.
On my w202 240T I can hear a slight whirring noise from the front right when turning right in a bend or going around in a circle clockwise. No noise whatsoever on the left or going anticlockwise.
I posted the question and asked around. Replies and suggestions pointed to the bearings. Checked the bearings on the front right and didn't find neither wear or excessive movement. All seemed fine.
The noise continued for a couple more weeks and finally in desperation I dropped the car at the local MB dealer who checked and didn't find anything either. However, they did change the rear axle oil which wasn't really necessary as I had it done a couple of months previously in a service by my trusted independent technician.
So after getting some new spare parts, I spent my Sunday in overalls and dismantled both left and right hubs and installed new wheel bearings and races on both sides. Washed all the bits, cleaned greased and checked everything around there (hubs, backing plate, calipers). The old bearings on the left and right didn't show any abnormal wear.
I went for a test drive round the block and guess what.....? The grinding noise is still there I then lifted the back end and placed it on stands so that was off the ground. Switched off the electronic safety controls ESP, ASR, etc., put it in drive and..... NO NOISE So that seems to exclude the transmission (gearbox) or prop shaft.
What could that grinding noise be
NEED some IDEAS before I go totally bonkers. Thanks
