My car started to bottom out easier while driving, i looked at front suspension and saw at elast one leaking bilstein shock. In prepping for the job how do i tell if springs need replacement? How about if one bilstein is leaking and the other isn't? lifetime replacement is only going to cover one? How can i have the warranteed replacement on hand when starting the job and get credit back for my expenditure on shock?
any other handy tips beforehand?
