IF THE SHOCKS ARE WEARING OUT ,THE SEALS WILL BE LEAKING OIL WHICH IN TURN LOOSES THE DAMPENING EFFECT, IF YOU ARE IN A TURN AND HIT A BUMP OR HOLLOW YOUR CAR WILL START TO WOLLOW ,LIKE A WATER BED , BEST TO GET THEM CHECKED OR CHANGED. ALSO THE KNOCKING NOISE COULD BE SOMETHING ELSE, SO GET CHECKED
