I'm working on the front right now, I have a jack under the spring probably 2 inches away from the rubber cup by the rotor. I tried jacking it up a little at a time, then trying to turn bolt. I've jacked it up so far now that the car is starting to lift. Am I jacking in the wrong place or is it just really hard to get the bolt started. I am turning counterclockwise. It has made just barely a turn. This is a 01 coupe and I don't think the thing could be to rusty as it has only been in the rain twice. I looked at Patches pictures it looks like his bottle jack is on the spring where it juts out a little. Could anyone give my any pointers. I've read all the posts and thought I had it down pat but I guess I don't. Thanks

 

You should have the wheel off and a bottle jack on the control arm not the leaf spring, your taking tension off the spring, the bolt could still be hard to turn but it will, also you can feel some drag from the rubber bushing, I used a long 10mm wrench for a little more leverage and it takes while keep going the out come is worth it.

The driver side on my car was a bitch, while the passenger side was easy.

 

I wouldn't jack on the spring as you may damage it.

I raise and lower mine all the time to set corner weights.

When I do it, I usually have the car off the ground on jack stands with the wheels off and the suspension hanging down. I do have the T1 springs though which have a hard nylon bushing instead of the stock rubber bushings, so mine may be easier to turn. Good luck.

 

I said it was on the spring but really it is on the lower control arm. I am doing the driver side also at this time. Do you need to jack it up right under the bolt or off to the side. Per Patches picture it looks like it is on the small part on the left of control arm that sticks out a couple of inches. Maybe I'm doing it right and just not putting enough elbow grease in it to get it started.

 

you should jack on the spring not the control arm as jacking on the arm loads the spring against the bottom of the arm (thats why its so hard to turn right now)
jack on the spring as the weight of the control arm and gravity pull down the jack pushes the spring up
its hard to turn (counterclockwise) for the first couple rotations as the friction between the rubber and bottom of the control arm increases as you turn after a few turns you should be able to turn it by hand i backed mine all the way off till the bushing touched the bottom of the spring and then turned it back (clockwise) a half a turn to finish

 

As per new post it is now lowered. The leaf spring was the ticket. Thanks
