My 2008 X5 has had a rear air suspension leak for half a year and the situation is getting worse. I finally bought replacement parts from Revain (Shockwarehouse dealer) and am very satisfied. Great price, easy installation. The hardest part for me was trying to install the new air spring in the correct hole position as you can't see it. I made the mistake of wearing gloves when doing this (to keep my hands clean) and wasted a lot of time. When I finally removed my gloves, it was fairly easy to feel and find the spot. The truck is now running normally again, no annoying morning air pump noise when we open the doors. And just so you know, the items we received were actually shipped direct from Arnott's warehouse with a very recent production date (November 2014 or so). Very happy with the purchase.
