Good day to all the knowledgeable folks on X5world. I have an 01 X5 4.4 with 83k miles and was wondering is there a certain mileage when you should replace your shocks and struts. My ride seems not to be as stable as it once was and i have already replaced tension struts,control arms,inner & outer tierods as well as the lower ball joints. I figure the only things left are the shocks and struts. What do you guys as well as gals(don't wanna be considered to be a sexist)think? Also what is your opinion on bilstein shocks for the rear and OEM on the front?
