Installation Instructions (Setup)
Professional installation is highly recommended for this automotive component.
Before You Begin:
- Gather all necessary tools, including wrenches, sockets, a torque wrench, penetrating oil, and a jack with jack stands.
- Park the vehicle on a level, firm surface.
- Engage the parking brake.
- Loosen the lug nuts on the rear wheel.
- Jack up the rear of the vehicle and secure it with jack stands. Remove the rear wheel.
Installation Steps:
- Locate the existing rear passenger side trailing arm.
- Apply penetrating oil to all bolts and nuts securing the trailing arm and allow it to soak.
- Carefully remove the bolts and nuts connecting the old trailing arm to the vehicle chassis and the wheel assembly. Note the orientation of the original part.
- Remove the old trailing arm.
- Position the new Dorman 905-527 trailing arm in place, aligning the mounting holes.
- Insert the bolts and hand-tighten the nuts. Do not fully tighten at this stage.
- Lower the vehicle slightly so that the suspension is under load (or simulate load with a jack under the suspension point) before fully tightening the bushing bolts. This prevents premature wear on the bushings.
- Tighten all bolts and nuts to the manufacturer's specified torque values. Refer to your vehicle's service manual for exact specifications.
- Reinstall the wheel and tighten lug nuts to specification.
- Lower the vehicle completely.
- It is recommended to have a wheel alignment performed after replacing suspension components.
Operation
Once correctly installed, the Dorman 905-527 Rear Passenger Side Suspension Trailing Arm operates as an integral part of your vehicle's rear suspension system. It helps control the fore-aft movement of the wheel, ensuring stability during acceleration, braking, and cornering. A properly functioning trailing arm contributes to a smooth ride, predictable handling, and extended tire life by maintaining correct wheel alignment.
Maintenance
The Dorman 905-527 trailing arm is designed for durability and minimal maintenance. However, regular inspection of your vehicle's suspension components is recommended.
- Periodically inspect the trailing arm and its bushings for signs of wear, cracking, or damage.
- Check for any loose or corroded fasteners. Tighten as necessary, adhering to torque specifications.
- Keep the undercarriage clean to prevent excessive buildup of dirt and road salt, which can accelerate corrosion.
- If any unusual noises (e.g., clunking, squeaking) or changes in vehicle handling are noticed, have the suspension system inspected by a qualified technician.
Troubleshooting
If you experience issues after installation or during the lifespan of the trailing arm, consider the following common problems and potential solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Clunking or knocking noise from the rear suspension | Worn or damaged trailing arm bushings; loose mounting bolts. | Inspect bushings for wear; check and re-torque mounting bolts to specification. Replace trailing arm if bushings are severely damaged. |
| Squeaking noise from the rear suspension | Dry or worn bushings; metal-on-metal contact. | Lubricate bushings if applicable (check manufacturer recommendations); inspect for contact points; replace trailing arm if bushings are worn. |
| Uneven tire wear on rear tires | Incorrect wheel alignment; bent or damaged trailing arm. | Have a professional wheel alignment performed. Inspect trailing arm for damage and replace if bent. |
| Poor handling or instability in the rear of the vehicle | Severely worn trailing arm bushings or other suspension components. | Inspect all rear suspension components for wear and replace as needed. |
