If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have
to wait for others to answer, or rely on mechanics and all. Plus i know a website that has very good manuals online, without expiry i.e. for lifetime. www.reliable-store.com

under the guard is a bearing and/or a rubber bush

you have to remove the shock strut to inspect and fix worn parts

They are stand alone shocks
Here are the part numbers you need.
MOTORCRAFT Part # AST236 Rear Left
MOTORCRAFT Part # AST235 Rear Right
About $100.00 for both parts.

Strut and Spring Assembly Removal

1. Raise the vehicle on a hoist.
   

1. Remove the front wheel and tire assembly.
   

1. CAUTION: To avoid damage to the 6mm drive hole in the front stabilizer bar link ball stud, do not use an Allen wrench to break loose or tighten to final torque the front stabilizer bar link-to-front shock absorber nut.
   Remove the stabilizer bar link retaining nut and disconnect the link from the strut.
   

1. CAUTION: Do not allow the halfshaft to move outboard. Over extension of the CV joint may result in the separation of internal parts, causing failure of the joint.
   Remove the strut assembly-to-steering knuckle pinch bolt. If required, slightly spread the steering knuckle to ease the removal of the strut. Pry down on the lower control arm and roll the strut base out of the knuckle. Do not pry on the halfshaft, as damage may result. Wire the steering knuckle up to prevent the halfshaft from moving outboard.
   

1. Partially lower the vehicle.
   

1. Support the strut assembly and remove the top three mount-to-strut tower nuts. Remove the strut assembly from the vehicle.
   

1. CAUTION: The strut assembly is under spring tension. Attempting to disassemble the strut without properly compressing the spring can result in injury.
   Using a suitable spring compressing tool, slightly compress the strut spring to relieve initial tension. Loosen the upper rod nut. Continue to compress the spring until the tension is relieved. Remove the upper rod nut.
   

1. Remove all upper mounting parts, coil spring, and coil spring isolators from the strut and save them for reassembly. Carefully note the position of each part during removal to ensure proper reassembly. Inspect each part for wear and damage as it is removed.
   

Installation

1. CAUTION: The bearing and seal assembly is press-fit onto the upper mount. The mount washers must be installed in the correct orientation.
   NOTE: Be sure to check the spring insulator for damage before assembly. If the outer metal splash shield is bent or damaged, it must be carefully bent back, so it does not touch the locator on the bearing and seal assembly.
   
   NOTE: New gas struts are shipped with the rod in a locked down position. To extend the new strut, remove the external tie down and/or rotate the upper end of the rod, counterclockwise.
   
   Install the coil spring insulator, coil spring, and upper mounting parts to the new strut assembly. Make sure the spring is correctly seated in both spring seats.

Of course this is only the cartridge, you have to transfer the spring, and the top mount of the existing strut. You need a pair of coil spring compressor to do the job. The basic procedure to replace a strut is:
Remove the top nuts that secure the strut assembly to the frame mount inside the engine compartment. Do not remove the center nut.
Mark the lower strut mounting location on the hub for installation reference. The alignment will be close if the new strut is installed in the same position.
Remove the bolts that hold the strut assembly to the hub.
Remove the strut assembly from the vehicle.
Mark the top mount for installation reference. Using a side mounted spring compressor, compress the spring and remove the top nut and retaining washer. Pull strut assembly out from the bottom of spring.
Slide the new strut assembly up into the spring and reposition the top mount onto the spring in the same position that it was removed. Install the retaining washer and top nut.
Tighten the top nut to the manufacturer's specifications and carefully remove the spring compressor.
Place the strut assembly back into the vehicle.

THe 93 Mazda has both actually. The shock absorber in this car is just one component of the so called strut assembly. Read on if you want the details: Shock absorbers are simple suspension dampers that control the unwanted spring motion of the vehicle's frame caused by the suspension's springs. Struts, or strut assemblies, basically does the same thing, although they are used on a different type of suspension system and performs another function, which is to provide support for the suspension system.

A strut assembly is composed basically of a shock absorber unit, a coil spring, an upper pivot, and a lower control arm. A lot of vehicles today make use of strut assemblies instead of simple shock absorbers for the suspension system. The most popular of these strut assemblies is the MacPherson Strut for the front suspension and its rear suspension counterpart, the Chapman Strut.

Mazda vehicles are well known for their sporty looks and performance, amazing a lot of auto critics when they accelerate on paved streets and highways.

Original Mazda struts are guaranteed to provide every Mazda passenger a pleasurable ride, whatever kind of trail they may choose to traverse.
