Replacing TOYOTA lower arm front bush is essential for a smoother ride, improved steering, and enhanced safety. It eliminates unwanted noises, prevents further suspension damage, and ensures stability, making it a vital maintenance task for your vehicle.
Before jumping into the replacement, here’s what needs to be done:
- Remove the cam bolt, lower shock bolt, and two strut bar bolts to access the lower arm.
- Important: Do NOT remove the lower arm ball joint during this process.
Install the Homemade SST
Attach the homemade SST to support the L-shaped cross-section of the lower arm. This will prevent it from deforming during the bushing removal and installation process.
Remove the Old Bushing
- Use the SST to apply pressure by tightening the nut.
- Listen for the satisfying crack sound that’s the old bushing dislodging!
Press in the New Bushing
- Align the new bushing carefully and press it in using a pipe with a 50 mm inner diameter.
- Ensure proper alignment to avoid uneven seating.
Reassemble with Torque Precision
- Once the new bushing is in place, reassemble the components.
- Tighten the cam bolt under a 1G load condition with a torque wrench (170 N·m).
Post-Replacement Observations
After the replacement, here’s what we noticed during the test drive:
- Noise Reduction: The creaking sound during body rolls was completely gone.
- Improved Damping: Small vibrations from road bumps were slightly reduced.
- Steering Feel: While subtle, the steering felt more responsive.
However, the improvements were modest compared to previous upgrades like replacing the strut bar bushings.
Cost Breakdown
Here’s a quick look at the expenses:
- Bushes (left & right): USD30
- Homemade SST: USD7
- Bushing Removal/Installation SST: USD 751
Conclusion
Replacing lower arm bushings without a hydraulic press is entirely doable with the right tools and a bit of ingenuity. While the results might not always feel dramatic, addressing worn bushings ensures your suspension system operates safely and quietly.
This DIY experience proves that with creativity and determination, even complex tasks can be accomplished efficiently. So, grab your tools and give your car the care it deserves!
