Do you turn the adjusting bolts to the right to raise the front end up? Mine is sitting way too low in the front, looks like its 'nose diving' while its sitting still.

Yes - Clockwise - tightening -  is raising the front of the car. It can throw out the alignment, so give that a check later.

also don't forget to loosen the lower control arm pivot nut prior to raising the up the torsion bars.

Thanks, I plan on getting an alignment done before putting it on the road.

Pivot nut? Is that the one on the front side of the k-frame that attaches the LCA to the k-frame.

Thanks,

Never heard of doing this. What is the reason?

I always take the weight of the car first when adjusting them. Give it a full turn lower the car of the jack stand, drive it and remeasure the height.

Yes, main reason is it takes the tension off of the pivot just enough and allows the suspension to raise up.  When I redid my front suspension and had to adjust the curb ride height, I remember something about this in the factory service manual.  Also, I seem to remember having to "bounce" the car occasionally to get the ride height to settle.  Remember to do one side a little and then do the other side this way you should get an average between the two instead of having a teeter totter effect.  Raising one side will drop down the opposite side.

Please lift the car & take the weight off before doing this , I have heard of 2-3 adjusters stripping in the nut & dropping extremely quickly

I do. I lifted up the front end and place the car on jackstands while adjusting. Now I got to lower it I raised it too high....looks like the General Lee fixin' to jump a creek.

No need to do this if you have poly LCA bushings.

Happened to me, I got lazy and figured I'd just reach under there to give it another turn. Luckily I had the jack under the car, just not raised, or my face would've been smashed!
If it ain't broke, fix it 'till it is.

I've raised & lowered mine more than the stock market has fluctuated this year. I finally found the spot I'm happy with , got it aligned, and haven't touched it again.. But if I had to guess I was under there 30X this season...  :lol:
