Gentleman,
I have an early but low mileage RHD 250SL Auto and I have a noise that comes from either the suspension or the exhaust, but only when I run over small “sharp” items like man-holes, pot-holes or cats eyes. Anything larger that exercises the suspension itself is perfectly quiet. I cannot replicate this effect from under the car, so not sure quite where to start.
To my ear, the sound is quite “light” as if the metal baseplate on the front discs is hitting something. Its is certainly not a heavy metal “knock” that I would expect from severe suspension wear. It appears to come only from the exhaust side (right) of the car and only after the car has been driven for more than 10 minutes. It is usually occurs there the front right shell runs over something small, but sometime from the back wheel as well, but always the same metallic “clank”
To me it sounds like the exhaust knocking on something, but I cannot work out what it could be. The exhaust is in very good condition and all rubbers are good and in place. I’ve pushed on the underbody head shield, but that seems secure. I’ve pushed and shoved the exhaust about by hand, but cannot replicate any contact is noise.
Other than paying someone a few hundred dollars to go over the suspension, are there any suggestions about what I can do at home and without a hoist?
Hopefully, someone else has experienced a similar problem and can help with some advice.
