Well Stazi said the kink should be on the passenger side...so that is what I was going off of. But looking at your picture...I thought the sway bar was on the front of the subframe...if that is the case then your bend would be on the passenger side...but maybe i'm wrong, I didn't get a lot ot sleep last night

As far as the "preloading" goes, can someone explain that too me? I'm not 100% familiar with what is meant by that

Thanks!

The subframe is upside down in the picture.

1 is the bend in the bar, if you where to flip it over to be installed on the car it would be in front of the rear wheels.

2 is the leading controll arms. Seeing that one you know it has to be on the drivers side when it's flipped over because it's the leading arm (first)

3 is the trailing arm. (last)

4 is the sub frame.



Preloading. You know when you jack up the car the strut and spring extend the wheel fully down. This also makes the leading (2) and trailing (3) extended fully down. If you where to loosen then tighten the bolts back up with the suspension in this position it loads the bushings in the arms to that position. When you drop the car back down it binds the bushings and causes problems and premature failure of the bushings.

To preload put the car on level ground raise it up with 4 jack stands and make sure it's level. Have all the rear bolts loose, jack one wheel up at the knuckle till the car comes about 1/8th inch or less off the jack stand then tighten the bolts on that side. Do the same for the other.
