6. Maintenance
TRQ suspension components are designed for extended service life and are pre-greased, requiring no additional lubrication upon installation. To maximize the lifespan and performance of your steering and suspension system, TRQ recommends replacing components in pairs, sets, or kits rather than individual parts, as this ensures balanced wear and performance across the axle.
Regular inspection of all suspension components during routine vehicle maintenance is advised to identify any signs of wear, damage, or looseness.
7. Troubleshooting
If you experience any issues after installation, such as unusual noises, vibrations, or changes in vehicle handling, consider the following:
- Loose Fasteners: Re-check all bolts and nuts for proper torque according to your vehicle's service manual.
- Improper Alignment: An incorrect wheel alignment can cause handling issues and uneven tire wear. Ensure a professional alignment is performed after suspension work.
- Component Interference: Verify that no new components are interfering with other parts of the vehicle's suspension or chassis.
- Damaged Components: Inspect all installed parts for any signs of damage that may have occurred during shipping or installation.
If problems persist, consult a certified automotive technician for diagnosis and repair.
