LS4 Performance - rear strut mount w/ or w/o soft ride

well sounds like the gxp has a bad right rear upper strut mount. i was looking tat the gm parts page and they have two options, with or with out soft ride. anyone know anything about this option and how i would know if i have it thanks. http://gmpartsdepartment.com/parts/2008/PONTIAC/GRAND%20PRIX/GXP/?siteid=214533&vehicleid=1440277&section=REAR%20SUSPENSION&group=REAR%20SUSPENSION&subgroup=SUSPENSION%20COMPONENTS&component=Strut%20mount

I was going to post up earlier, but I decided to just wait and look for the responses haha :angel:

Well would probably not have the soft ride

What issue has brought you to suspect the rear strut mount.

i have a clunk from the right rear. its a hard hitting clunk over larger holes/ bumps. the strut looks dry so i assume it is ok.

not sure how or if it helps but :chug: your tires have a good amount of how it rides. my tires run at 52lbs and its a really rough ride on shitty roads.

our gxp has a clunk from the right rear but only going over bumps slow.

Before you purchase the part I would take an hour of your time and test the affected side. Jack the car up and pull the rim off, reach up and grab the strut and try to move it up and down and side to side to see if there's play in the bearing. If not that may not be your issue. It could be the strut starting to go.

talked to my dealer he gave me build code FE4 as special suspension and FE1 as soft suspension he said with my vin he could tell which it had

checked the build sticker in the trunk it has FE4 so special suspension

I actually know the answer to this one. After chasing the same thing for a couple of years and taking the suspension apart--The bilstein strut seals stick and the noise comes through like a thump. A shot of WD-40 up inside the strut boot will quiet it down for a while. Graphite based chain lubricant works better.

ill give that a try gtostan hopefully it takes care of it, id rather spend money on the electric cutout than a strut mount!
