The purpose of a MacPherson strut, much like a shock absorber, is to dampen harsh spring movement and provide a means of dissipating the motion of the wheels. 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.

When it comes to removal and installation of parts such as ball joints, universal joints, and truck brake anchor pins , Astro Pneumatic Tool's Ball Joint Service Kit contains a "C" frame press, 3 receiver tubes, and a variety of adapters that are useful for removing rusted and corroded bits.

After the ball joints are loose, (again assuming that the whole front end assembly is removed from the car) unscrew the ball joint nuts so that there is about a half nuts worth of threads holding it on. Remove the top and bottom bolts holding the inner ends of the ‘A' arms to the crossmember.

Axle shafts are removed with an 8mm socket; rotate the axle shaft so that two bolts are removed on the inside at the top. Before painting, I had to drill the holes on the upper control arm where the ball joint rivets once were. So I was obviously able to get the front conical bushing out (man, was it trashed) and now I can't get enough play to clear the tube from the radius arm where it goes through the control arm.

Anytime a spring wears out sooner than it should, the vehicle will display a few common side effects , including the vehicle leaning to one side or a rough ride. A tube or pipe is used to clear the pivot shaft as the assembly is pressed into the lower control arm.

In addition to our own high quality conversion kits, we carry a wide variety of products from industry leaders like Air Lift, Monroe, Rancho, ReadyLIFT, and SuperSprings. The control arm bolts have flats on the inside to keep them from spinning during removal; try to keep pressure on the socket at all times if you use air tools for removal.

Because dirt cars typically see a lot of dynamic shock travel, this can at times produce what we call side loading. Need a service of your fork, shock absorber or steering damper? DO NOT use blocks of wood, or other material to make up any gap between the jack and control arm- instead, lower the car and shorten the chain.

11: Loosen the upper control arm mounting bolts and carefully remove the shims. Figure 6. Uppermost boom section is resting on ground, and no pins between uppermost boom section and crane body are to be removed. Remember that there will be a lot of spring pressure on ‘A' arms, so be very, very careful when you remove these bolts and nuts.

The replacement ball joints use bolts that are larger in diameter than the originally riveted area so they won't fit if not drilled out. It's also useful for removing similarly-sized bushings on the eyeholes of leaf springs. Remember to do both the upper and lower control arm bushings.

Lastly, in rear suspension, some bottom out control may be built into the bike. Springs absorb the energy and shocks control the release of that energy. High speed compression is sometimes used as a bottom-out control and some suspension products even have specific compression damping features that control the end stroke for bottom out control as well.

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.

If this type of problem is found, it may be a good time to sell the customer an upgrade to variable-rate springs. Jack up the car and place it on jack stands or other suitable supports under the control arm (not the strut or radius rod). Now go to the front end of the strut rod, and look where it comes through the lower control arm.
