Hello thanks for the reply. I did find brown crud on the top of the outside of the strut tower as you indicated to look. Funny thing, I took my X5 to dealership today and was denied any warranty work what so ever on the suspension, as it had after market (H&R springs), on it?? Whatever....... Looking to have the bushings replaced on both front struts as the sound is terrible going over bumps. I do want it make sure that is the only problem I am having. Thanks again for the information.
