The fourth generation Corvette was a radical departure from General Motors early Corvette engineering. It eliminated a perimeter frame to support the suspension and driveline. Two front frame rails integrated into the first ever Corvette uni-body construction. This made for an interesting driveline mounting installation. The front suspension subframe was bolted to the frame rails while providing engine mounting points. Before you can remove any coil spring from its mounting point on a vehicle or on a strut, it must be clamped down to a shorter height. Don't forget that a sagging rear spring can also cause a ride height change in the front of the car. This is how all of the bushings can be removed once the sleeve is out. They are not vulcanized to the control arm or camber rod ends.

Final assembly will wait until the suspension and drivetrain are loaded into the car, at which point we will install the steering box, shocks, and torsion bars. By far the front upper and lower control arms last the longest. If bushings are so tight that pressure springs yoke end of knuckle, place Spacer J 722-2 between yoke ends to one side of bushing.

With PUSH Factory Fork Systems you also get cutting edge suspension technologies and materials simply not found in production forks and shocks. Not only do we look at all the seals, -rings and wear bands, but we also pay very close attention to the bushings inside the seal heads of the shocks.

Loss of control and vehicle rollover may be the result of severely worn, or broken coil springs. 15: The upper ball joint can be removed by using a drill bit, chisel or die grinder to remove the rivets. This location, along with longer spring bolts will lower the rear of the car between one and two inches.

Remove rod and bushings from pin on frame bracket. Disconnect links from 1951 Buick rear shock absorber arms. When it comes time to assemble, make sure that the control arm bolt flats are in the correct position and seated flat against the frame or a sudden change in vehicle control can be experienced.

Like the upper control arms, the sleeve is pressed out. the rubber is then easily removed. Overload shocks have a coil spring around them to increase the load carrying capacity of the suspension (these also tend to ride stiffer than standard replacement shocks).

With the spindle knuckle assemblies on the bench, the spindle rods can be removed with the 24mm socket and wrench. The bushings are greased on both sides, and the seals get enough grease to make them slide easily for assembly and when the fork is first used. Rear suspension disassembly begins with rear spring unloading.

Remove grease fittings and press old bushings from steering knuckle, using Driver J 1382-3 and Press Plate J 1649. Support car frame by another jack, then slowly lower the jack under lower control arm. Weak shocks and struts won't necessarily create a driving hazards if you continue to drive on them, but there are studies that show worn shocks increase the distance it takes to stop a vehicle on a rough surface.

Mercury Cougar Air suspension replacement kits like air springs, compressors, dryers, and solenoids are available so purists can keep their air suspension riding as smooth as the day they bought their vehicle. Your vehicle will need new shocks or struts if the originals are worn out, leaking, or otherwise damaged.

When the ball joint stud threads are exposed, install and tighten the nut. Connect tie rod outer end to steering arm, and connect stabilizer link to lower control arm. 06: Disconnect the idler arm bracket from the passenger side of the frame and then use the tie rod separator to remove the control valve stud from the Pitman arm.

The leaf spring is supported by the lower control arm valley. Run a "safety chain" (B) through the spring and around the lower control arm- leave about 10" of slack in the chain- to allow the lower control arm to drop enough to get the spring out. A few whacks should loosen it. If you can't get it that way, you must drive a balljoint separator between the a-arm and the ball joint.

A "pickle fork" or ball joint separator tool makes this step a lot easier - Ed. Protect, strengthen and improve the performance of your suspension with components that make your fork and shock absorber look like ‘works' suspension with DLC (black) coating. This is because the sagging rear effectively moves the top pivot point of the front suspension (upper ball joint location on a control arm-type suspension) rearward, which obviously tilts the steering axis rearward, increasing caster.
