Description And Operation
A MacPherson type design strut assembly is used in place of the traditional front suspension upper control arm and upper ball joint. The bottom of the strut mounts directly to the steering knuckle using two attaching bolts and nuts going through the strut clevis bracket and knuckle. The top of the strut mounts directly to the strut tower of the vehicle using the three threaded studs on the strut assembly's upper mount.
The strut assembly includes the following components:
- Lower Spring Isolator (1)
- Strut (damper) (2)
- Dust Shield and Jounce Bumper (3)
- Upper Spring Isolator (4)
- Bearing and Upper Spring Seat (5)
- Upper Mount (6)
- Coil Spring (7)
Each component is serviced by removing the strut assembly from the vehicle and disassembling it.
Coil springs are rated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service. If a coil spring requires replacement, be sure that it is replaced with a spring meeting the correct load rating for the vehicle and its specific options.
