Thumbs up 2006 955 Front Suspension DIY...SUCCESS!

Just completed a DIY front suspension refresh on my 2006 Cayenne 955 because the front tires were balding on the outer edges. Replaced front struts (complete assembly), upper and lower control arms (TRW), sway bar end links (probably unnecessary) as well as brake rotors, hardware and pads. The main issue I had was getting the lower control arm BJ back into the hub mount due to the stiffness of the BJ. It took a lot of frustrating attempts but I was finally able to get both sides to seat properly. It seems that the rubber boot and clamp for the front axle causes clearance issues with the top of the control arm's BJ housing...especially if the clamp's locking "clip" is rotated to the bottom. I almost decided to cut the clamp and boot but then, VOILA...the part dropped into place. It really helps to use cinching straps to "float" the weight of the lower control arm and a jack to adjust height so it's easier to manipulate that heavy chunk of steel...

From my observation, the control arm bushings were a little soft (lower rears were the softest) but the BJ's were totally shot. Struts must've been on the edge too because before the refresh, I could bounce the front by pushing down. After refresh, I can't create ANY motion. No squeaks or creaks and now the vehicle FEELS AWESOME when tracking speed bumps and potholes!

BTW, with the standard suspension (non-adjustable), you do NOT have to remove the front fender liners as some DIY's on YouTube state. However, take the time to remove a few of the liner screws to slightly "peel" back the liner (closest to the passenger cabin) to access the drain covers and clear them out. You'll thank me later...

Oops...forgot to mention that I have just over 95k on the OD and it appeared that all the components, including the brakes and rotors, were original!

Just re-read my post and realized I meant that the brake's calipers, fittings and rotors were original...DOH!
