Duster Front End

Crank it to the top. Roll the car back and forth at least a total of 8 ft. Then start lowering it to where you want it. If the front tires come off the ground for the adjustment, then the car has to be rolled after that adjustment,to relax the suspension and tires. All the bushings were installed at the lower ride height and tightened there. They are pre-loading the suspension to that lower ride height. You will have to overpower that preload. They can be very stiff.
Slant six bars are weak to start with so if that's what you have,don't expect much.
If you loosen the LCA inner pivot nut two turns and bop the pin in a few thou, it will relax the preload there. Set the ride height, then tighten the nuts at ride height, after the last relaxation roll.
