Driving a good car makes you ignore some seemingly small parts underneath your seat. If you hear a weird squeaking or high-pitched sound that does not come from the suspension or the brakes, then it may be your car's spring seat that is causing it. A spring seat is a pair of thick, disc-like rubber bushing that lessens the shock on the seats caused by turning and passing over bumps. This component wears out after a long time and needs to be replaced immediately in order to relieve you of the distracting noise. The spring seat-the part where the spring sits-is located on each end of the seat's spring assembly, one next to the strut on the upper part and the other after the spring isolator on the lower part.
Anyway, here are the tools you need and the steps you have to follow when replacing your worn spring seat.
Difficulty level: Moderate
- A new pair of spring seat (made from rubber or polyurethane elastomer)
- Ratchet set
- Spring compressor
- Duct tape
Step 1: Use the ratchet to remove the bolts that hold the seat to the floor of the car. Remove the seat and turn it upside down. You may need to slide the seat forward or pull it upward to loosen it out of the spot.
Step 2: Use the scissors to cut the material covering at the bottom of the seat. Locate the spring assembly that is making the sound. Take note that each car seat has more than three spring assemblies inside, which give you comfort when assaulting road bumps.
Step 3: Focus on the problematic spring assembly. Use the spring compressor to squeeze the coil spring together so that you can disassemble the parts and work freer on the spring seat.
Step 4: Remove the parts from the upper strut mount downwards until you get to the lower spring seat. Use the pliers for this task. Align the parts according to the order of disassembly so that putting them back together later will be faster.
Step 5: Re-assemble the parts back starting from the lower strut mount up. Install the new spring seat components as you go along. Attach the lower spring seat, bumpstop, boot, lower spring isolator, coil spring, upper spring seat, and upper strut mount.
Step 6: Repair the torn material covering at the bottom of the seat using the duct tape. Replace the seat back to its position and re-attach it to the floor securely. Test for noise by rocking the front part of the seat or by driving the car through bends.
