I have two questions for any of you suspension gurus out there.

1) I just finshed the rear new suspension component install and torqued everything down with the weight of the car on the wheels...however....having not driven the car in some time, I did not realize that the gas tank was on E. Should I fill the tank 1/2 full and redo the torque on the parts or is this not really cause for concern since I still had the weight of the car on the bushings?

2) When ever I do front end work I use dual jacks under each pad to lift the car and I just throw the safety stands under as a precaution. My question is, I want to put the jack stands under the jack pads to hold the car while I replace the front end components so where would be the best place to jack the car up to do that without incurring damage?

Thanks for any advice.

Rick

Hopefully a guru will show up, until then:

1 - don't worry about it

2 - There is a jacking point built into the front subframe towards the back.

Perfect on both accounts Rao. I was hoping I wouldnt have to redo the torque values on anything. Plus that would have meant getting all new lock nuts.

Much appreciated.

Here is a picture of the subrame jacking point (the arrow shows the front of the car and the jacking point is circled):

Thanks Rao!

The picture was perfect. I plan on getting the beast in the air tonight.

Rao,
I've always jacked on the jackpads and then slid a stand under the tubular X frame down on the lower (rearward) legs near (but not under) the place where the small welded flange is. Anything wrong with this?

I don't think so, but I prefer using the jack pads and jacking the front and rear from the center jacking points. Of course with a lowered car you don't have a whole lot of choice, but when I am stuck with some unfortunate lowered car

I usually lift it in 2 steps, first using a jack on the side jack pad and then set the car down on on a ramp, then you can use the center jacking point.
