Core Product Description

The 43503-28010 Hub Sub-Assembly is a front axle wheel hub component for Toyota Town Ace, Noah, and Liteace models. Also known as a front wheel hub assembly or front axle hub, this component mounts the front wheel and supports vehicle weight while allowing smooth wheel rotation. It includes the wheel hub and bearing as a pre-assembled unit.

This hub is specifically for the left-hand side (LH) of the vehicle. According to Toyota parts catalog data, this part was used on Toyota Town Ace/Noah models from December 1998 to November 2001, including SR40 and CR40 chassis . The assembly is designed for front axle positions and serves as a direct replacement for the original component.

Common Symptoms of a Failing Front Hub Assembly

If you are experiencing any of the following symptoms, your front hub assembly may be failing and in need of replacement:

• Whining, roaring, or grinding noise: Noise from the front wheels that increases with vehicle speed – this indicates bearing wear

• Vibration through steering wheel or floor: Front wheel vibration felt through the steering wheel or floor that changes with speed

• Excessive play in the front wheel: Wobble or play when the wheel is lifted and checked at 12 and 6 o'clock positions

• Uneven or rapid tire wear: Abnormal or accelerated wear on the front tires

• Grease leakage: Visible grease or oil around the hub area

• Vehicle pulls to one side: The vehicle drifts during driving, indicating bearing or hub misalignment

If you have confirmed these symptoms through inspection, replacing the front hub assembly is the recommended solution.

Installation Tips

Important: Front axle components are critical safety components. Professional installation is strongly recommended. Safely raise the vehicle and support it on jack stands.

Clean the spindle thoroughly and inspect for damage. Install the new hub assembly onto the spindle. Install the hub nut and tighten to factory torque specifications. Reinstall the brake caliper and front wheel. Test drive and check for unusual noise or vibration. Professional installation is recommended if you are not familiar with front axle repairs.

After Replacement Still Having Issues?

Replaced the hub assembly but still having issues? Check these:

1. Is the axle nut torqued correctly? – Incorrect torque is the #1 cause of premature bearing failure

2. Is the wheel alignment correct? – After hub replacement, check alignment

3. Are the wheel bearings on the other side worn? – If one side was worn, the other may also need replacement

4. Was the hub seated properly in the steering knuckle? – Ensure the hub is fully seated

5. Is the brake rotor warped? – A warped rotor can cause vibration that may be mistaken for bearing issues

 Related Product Recommendations

Front Brake Rotor – The brake rotor mounts to the hub. If the rotor is worn, scored, or warped, it should be replaced while the hub is being serviced.

Front Brake Pads – Inspect the brake pads for wear. If the pads are worn thin, replace them. Contaminated pads should always be replaced.

Axle Nut – The axle nut secures the hub to the drive shaft. On many Toyota models, it is a single-use part that must be replaced each time the hub is removed.
