My 08 LE Longbed was taken into the shop for having a bad front end clunk when going over bumps. They suggested they perform the latest TSB which replaced the front springs for the shorter springs from 07. I was reluctant to allow them to do this as I didnt want my front end to drop 1.5". When I refused they stated that because I wasnt allowing them to perform the fix per Nissans advice they would have to mark down that I was refusing warranty work. I chewed on it for 2 weeks and decided to go ahead with the fix as I couldnt live with the clunk any more. The truck now has the rake of an 07 and all though greatly reduced the clunk is still there. Since the dealership has no other ideas on how to fix my problem completely I have decided to try to fix it myself. I want to replace the stock shocks all the way around but now that I have 07 front springs Im not sure which ones to buy. I want to go with Bilstein 5100's here Bilstein shocks and struts for cars and trucks - Shockwarehouse.com but am not sure if I need to replace the springs back to the original 08's as well? Can I order all Bilstein 5100's from shockwarehouse, install the 08 springs back on and have everything directly fit or is there any kind of modification I will need to do? Sorry for the long post and thanks for anyone's input.
