Parts for your 1999 Toyota Avensis-Control arms

Guide to Replacing and Maintaining Control Arms on Your 1999 Toyota Avensis

When it comes to maintaining your 1999 Toyota Avensis, the control arms are an essential component that often get less attention than they deserve. These vital parts are responsible for connecting the vehicle's suspension to the chassis, ensuring smooth and stable handling. If your Avensis has started to exhibit symptoms like uneven tyre wear, vibrations, or a wandering steering wheel, it might be time to examine your control arms.

Before you start thinking about replacement, ensure a proper diagnosis is made to confirm the control arms are indeed the source of the problem. Typical signs to watch for include clunking noises when driving over bumps or during turns, a noticeable discomfort in the steering, and visible wear or damage to the control arm bushings. These symptoms indicate that it's time to give your control arms a thorough inspection or consider replacing them.

1. Gather the Necessary Tools: You'll need a jack and jack stands to lift and secure the vehicle, a socket set, a wrench set, and possibly a breaker bar for leverage. It's also wise to have some penetrating spray on hand, as the bolts may be rusty or seized.
2. Safety First: Always ensure the vehicle is on a stable, flat surface and that it's securely supported on jack stands before you start any work underneath.
3. Remove the Wheel: Use a lug wrench to take off the wheel, giving you access to the suspension components.
4. Access the Control Arm: Before removing the control arm, inspect for any signs of wear or failure. Look at the bushings and ball joints for cracks, splits, or excessive play.

The control arms typically attach to the car at two points: the ball joint on the hub assembly and the other at the frame or bracket. Start by removing the bolts that anchor the control arm to the chassis. You'll usually find one at the frame or subframe mount and another at the steering knuckle. Removing the old control arm can be challenging, especially if the bolts are worn or rusted, so take your time and apply penetrating spray as needed.

After the old control arm is out, compare it with the new one to ensure you have the correct part. Slide the new control arm into place, aligning it with the mounting points. Securely tighten the bolts according to your vehicle's specified torque settings which are typically found in the service manual.

• Tighten the ball joint nut securely.
• Lower the car gently and replace the wheel.
• Torque the lug nuts to the manufacturer's specifications.

Finishing a control arm replacement might sound complex, but with patience and attention to detail, it's a doable project for even moderately seasoned DIY mechanics. Regular checks as part of routine vehicle maintenance can prevent complications down the road. Sometimes all you need is a simple bushing replacement or tightening that can stave off full-blown repairs longer than you might expect.

Whether you relish in the satisfaction of a DIY accomplishment or prefer delegating such tasks to a trusted mechanic, keeping those control arms in shape is a crucial piece of the puzzle in ensuring your 1999 Toyota Avensis rides smoothly and safely year-round.
