The springs of the Pontiac Grand Am are part of the car’s strut assembly, which serves to enable the car to grip the road firmly and which in turn offers the passengers a smooth, easy ride. If you need to have the springs replaced, do know that this procedure could be quite complicated and it may be best, especially if you don’t have enough experience with automotive repair, if you hire a professional for this job. However, if you feel up to the challenge, here are the basic steps for replacing the springs in your Pontiac Grand Am:
- Purchase coil springs that are compatible with your Pontiac Grand Am. Springs are made to customize not just car models but the years they were manufactured: make sure that the ones you purchase correspond to your car’s make and model.
- Prepare the materials. Apart from the coil springs, you will also need the following: floor jack and jack stand, strut compressor, socket wrench, sockets, box wrench, adjustable crescent wrench, lug wrench, torque wrench, and safety goggles. You will also need alignment rods J-34013-27.
- Open the hood of the car. You will need to locate the strut assembly inside. Look out for the bulky circular tubing that holds the strut assembly. These bulky circular tubings will be on both the leftmost and rightmost corners of the car. These are called the strut towers, and they hold one part of the strut assembly; the other part will go down to the steering knuckles by the wheels of the car. You should remove the bolts securing the strut towers after you have removed the fasteners at the wheel’s steering knuckle (see next steps).
- Jack up the vehicle with the floor jack and jack stands.
- Remove the front wheels of the car. You will then be able to have access to the steering knuckle assembly. Remove the fasteners at the sides of the steering knuckle with a torque wrench. Once you remove the bolts from the strut towers, finally, take out the strut assembly. At this point you may want to bring the entire strut assembly to a professional so they themselves could replace the springs; do know that replacing springs yourself could potentially cause injury when not done properly. If you still decide to troubleshoot this problem yourself, read on.
- Mount a vise to a fixed surface, such as a table. Then, secure the strut assembly to this vise, making sure to place it in a vertical position.
- Remove the strut assembly’s damper shaft nut spring cap. You will need a socket and a wrench for this purpose. Make sure that you compress the spring while doing this step. Again, if you do this improperly you will risk harming yourself, so be very careful! You should take the pressure off the springs or else they could be released from the strut assembly with potentially dangerous results.
- Install the alignment rod through the strut assembly’s spring cap. While doing so, you should compress the strut to about ½ of its original height. Once the alignment rod is through the strut assembly, it will help you remove the components, particularly the coil springs. Inspect each of the components for wear and tear.
- Install the replacement spring. You will reassemble the strut assembly with the new components by again mounting it in the compressor. Tighten the strut mount. Replace it in the car.
Remember, this task is moderately challenging so you would have to be sure that you have some experience with automotive repair before you embark on this. Good luck!
