Installing Bilstein Shocks
It turns out that its a 21 MM nut.
I got the old shocks out, and just as I suspested the driver's front shock was completly dead, along with the passenger front shock, the rears were also just about dead. Man what a difference in the ride now.
Tools that I neede to instal the Bilstein shocks were:
1 3/8 drive ratchet
1 7mm hex head socket that is 3/8
1 19mm gearwerench ratchating werench.
time to get out your bottle jack, to push the lower part of the shock up into the mounting bracket, as the Bilstein's are very stiff.
You have to hold the shock stud with the 7mm hex head socket, while you tighten up the 19mm nut.
also be careful not to cross thread the lower shock bolts on the front shocks.
I didn't catch it on the passengers side, but I cought it on the drivers side, so I had to get a new bolt and nut from the dealership.
For the rear shocks do not cut the straps off of the shocks tell you have them bolted up, as you will not be able to push it back up to bolt it up.
