Check the shocks first they will squeak pretty bad when going out ( dried out seals ). Bushings will squeak but they would have to be pretty bad to do it when just pushing on the front end.
Most likely one of the bushings in the suspension moving a bit when you hit a bump, track it down and tighten it if you can. also check the shocks they will squeak when going bad

no. ADDED: It is an "administrative suspension."
Brand new hydraulic shocks that run an electric generator. The shock action pumps the motor impeller and makes electricity. Bose just came out with electromagnetic suspension. For a truck you might get some excess energy output with magnetic/electromagnetic suspension with coils picking up the moving magnetic flux from the suspension cylinders and making power. Magnetic field moving past a wire is how a generator works. Put magnets on the moving rods and wrap it with coils of solid copper wire. A linear generator.
these pins need to be cut to get them out once cut they can then be knocked out and new pins and bushings installed the hardest part is cutting the old ones i have used a metal bladed Sabre saw to get the reach with out moving actual hinges
If we are talking about while moving there is a serious problem with steering suspension or brakes.
Teary envy from Chevy guys. listen for the sqeak, determine if it is coming from the interior of the car or one of the moving parts, if it is in the steering check your bushings first.
Variety of possibilities. Fluid blockage to the caliper, frozen piston, slides that are not moving, pins that are not moving, sagging suspension, groove worn into caliper bracket.
A suspension bridge does move. Over the course of history engineers have implemented the use of different materials so suspension bridges are not as "wobbly", but they still move. They also have parts called rockers which are locked in between the truss and the arches. This keeps the bridge from being to stiff and helps release some of the stress.
Not while the suspension is active. You need to appeal for reinstatement of your license.
usually a sagging door on a Chevrolet truck is due to worn out bushings, pins or other small and replaceable hardware that hold the joints together. These moving parts bear a good amount of stress and weight but it is very difficult to get any lubrication into them because they are small and tight. New bushings and pins (you need two sets for a door - one for each hinge) are usually about $8-$10 each set (one set of bushings and a pin for one hinge) this guy has specialty bushings that you can lubricate to prevent your new bushings and pins from being worn down. His site also has diagrams from the GM manual for their procedure on how dealerships should repair this problem http://www.andyz28.com/truck/ GM diagrams at http://www.andyz28.com/3rdGen/gmmanual.HTML
Do you mean drivers license suspension? If so, it depends on the insurance company. It used to be that non-moving violations didn't count on your insurance rating but in the past few years they have starting allotting points for items like this.
