W11 E280 Squeeking

[phase]

Hi all, I'm a complete non techie so bear with me please, I have a W11 E280 CDI Auto on a '56 face lift, only done 39k. Every time i go over a speed bump or even a small bump in the road i get a high pitched squeak coming form the wheels area not sure which one., I have read a few post which say to spray some silicone dry spray on the parts behind the wheels. Would this be the right direction or something else? any help much appreciated. Thanks.

Take it to an indi and have it checked out.

TMS in Kirkham will sort it.
