Pontiac Shock Absorber and Strut Assembly Repair for Optimum Driving Safety
Even though your Pontiac shock absorber and strut assembly are made from premium and durable materials, they can still deteriorate due to natural wear and rough handling. The shock absorber and strut assembly are essential components of your car's suspension system. They keep your tires in contact with the road, so they play an important role in the steering stability and brake handling of your vehicle. This is why it's important to patch them up when you find the slightest symptom that leads to the possibility of your suspension system being on the blink. When you're having trouble stopping the car, or when your car is swerving or nose-diving, you know something's not right. Bad vibrations, side slides, and uneven tire wear should also give you a hint that your suspension system is faulty. Before anything bad happens, it's best if you have your car checked. A professional is best for the job since the repercussions can be serious when it's not done right. However, if you are confident about your expertise level, then here's a guide to help you out.
Difficulty level: Moderate
Things you'll need:
- Floor jack
- Jack stands
- Socket set
- Combination wretch set
- Pry bar
- Spring compressor
- Side cutters
Step 1:To start repairing your Pontiac shock absorber and strut assembly, lift your vehicle using a floor jack and secure it with jack stands. Loosen and remove the two bolts at the bottom of the strut using a wrench, socket, and ratchet. Do the same to the upper shock bolt where the uppermost portion of the shock meets the frame of your car.
Step 2:From under the hood, loosen and remove the three nuts that hold together the strut and the tower. Do the same to the lower shock bolt using a socket and a ratchet. The lower shock bolt is where the lower end of the shock comes together with the rear hub assembly.
Step 3:Use a pry bar to detach the bottom of the strut from the mount on the steering knuckle, then pull the strut from the vehicle and yank out the shock from the upper and lower mounts. After this, hook the spring compressor over the coils of the spring and tighten it with a wrench.
Step 4:Loosen and remove the upper strut nut, then tug on the upper strut plate to remove the spring. Position the spring over the new strut and place the upper strut plate in it. Use a wrench to tighten the upper strut nut. Afterwards, set the new shock into the upper mount and hand-tighten the upper shock bolt into it.
Step 5:Let the spring extend inside the strut assembly by loosening the spring compressor to the right length. Cut the plastic strap that holds together the new compressed strut and the side cutters.
Step 6:Place the strut assembly under your car and thrust the strut studs from the upper part through the holes in the strut tower. Grip the bottom of the strut and push it against the mount on the steering knuckle. Thrust the lower strut bolts through the holes at the bottom of the strut. Hand-tighten the nuts and bolts to finish this step.
Step 7:As the shock extends, steer it into the lower mount. Put the lower bolt through the shock's lower hole. Tighten both the upper and lower bolts with a ratchet and a socket.
Step 8:Repeat the process for any additional components to your Pontiac shock absorber and strut assembly. When all is done, lower your car to the ground.
