Replace Your Trailing Arm Bushing in 10 Easy Steps: A Guide for Beginners

Trailing arm bushings play a crucial role in maintaining your vehicle’s suspension system. Over time, these bushings can wear out, leading to a loss of stability, increased noise, and even premature tire wear. Replacing trailing arm bushings can be a daunting task, but with the right tools and a bit of patience, it’s a job that even novice DIYers can tackle. In this comprehensive guide, we’ll walk you through the steps on how to replace trailing arm bushings, ensuring a smooth and safe ride.

Safety First

Before you begin, it’s essential to prioritize safety. Park your vehicle on a level surface, engage the parking brake, and chock the wheels to prevent any unexpected movement. Additionally, wear appropriate safety gear, including gloves and safety glasses.

Tools and Materials

To replace trailing arm bushings, you’ll need the following:

• New trailing arm bushings
• Socket wrench set
• Torque wrench
• Jack and jack stands
• Pry bar
• Penetrating oil
• Anti-seize lubricant

Step-by-Step Instructions

1. Preparation

• Locate the trailing arms, which are typically found on either side of the rear axle.
• Mark the position of the trailing arms relative to the vehicle’s frame for easier reassembly.

2. Support the Vehicle

• Position a jack under the vehicle’s frame near the trailing arm you’ll be working on.
• Raise the vehicle using the jack and secure it with jack stands.

3. Remove the Wheel

• Use a socket wrench to loosen the lug nuts on the wheel associated with the trailing arm.
• Remove the lug nuts and take off the wheel.

4. Disconnect the Sway Bar

• If the sway bar is connected to the trailing arm, you’ll need to disconnect it.
• Locate the sway bar link and use a socket wrench to remove the bolts securing it.

5. Remove the Trailing Arm

• Locate the bolts that connect the trailing arm to the vehicle’s frame and suspension components.
• Apply penetrating oil to the bolts and allow it to soak in for a few minutes.
• Use a socket wrench to remove the bolts and carefully lower the trailing arm.

6. Remove the Old Bushings

• Use a pry bar to carefully pry the old bushings out of the trailing arm.
• Clean the surface of the trailing arm where the new bushings will be installed.

7. Install the New Bushings

• Apply anti-seize lubricant to the new bushings.
• Insert the new bushings into the trailing arm and use a pry bar to press them into place.
• Ensure the bushings are fully seated and aligned correctly.

8. Reinstall the Trailing Arm

• Lift the trailing arm back into position and align it with the bolts.
• Thread the bolts into place and tighten them using a torque wrench to the manufacturer’s specifications.

9. Reconnect the Sway Bar

• If you disconnected the sway bar, reattach it by inserting the bolts and tightening them using a socket wrench.

10. Reinstall the Wheel

• Place the wheel back on the hub and tighten the lug nuts by hand.
• Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

11. Lower the Vehicle

• Slowly lower the vehicle from the jack stands and remove the jack.

12. Repeat for the Other Side

• Repeat the steps for the other trailing arm to replace the bushings on both sides of the vehicle.
