Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** the noise diminishes when you turn to the right I'd suspect a noisy wheel bearing or a noisy tire tread. I would not suspect a fault with the transmission or with the wheel alignment.
Let me know if you have any questions.
You're quite welcome. Typically it will be a wheel bearing or tire tread issue. If the noise goes away when you swerve to the right I'd suspect the right front wheel bearing or tire causing the problem.
