On my 2008 S550 with 70,000 miles I have experienced no squeaks from the front end until both struts were replaced and now VERY squeaky on non-smooth roads. Ideas ?

 

Check your lower arm and the sway bar.

 

Thanks ! Car in now for inspection ! I will mention this to them !

 

Squeaky front end no longer squeaks ! The dealership greased the front suspension and now rides quietly !

 

Its most likely the front sway bar that causes this really bad squeaking. The 2 contacts where the rubber mounts are is the cause. Grease works.

 

What type of grease should I use; have the same issue

 

Grease works as a temporary solution and solves the squeaky cracking over bumps and humps... but the correct procedure to remedy the problem is the epoxy solution.

Good luck!
