MAINTENANCE / REAR AXLE

Kei van axle housing replacement | Using a used part to resolve noise

A suspension repair at WORKS in Tsuzuki-ku, Yokohama, on a kei van with over 300,000km. Loud hub-bearing noise led to replacement using a used axle housing.

Considering a bearing replacement or complete assembly

Bearing removal risked damaging the shaft, so methods and costs were reviewed. A used assembly was chosen instead of a dealer assembly replacement quoted at approximately ¥300,000.

A used part from a vehicle with between 20,000 and 29,999km

The housing sourced from Crest Parts reportedly came from a vehicle with mileage in the 20,000km range. In this case, the approach saved over ¥200,000 against the quote above.

Cost differences apply to this vehicle and quotation only. Methods and costs depend on model, condition and used-part availability.

Ask about kei van noise & suspension repairs

Tell us the model, year, mileage and when the noise occurs. We can discuss maintenance options based on the vehicle’s condition and your budget.

Care in every exterior detail.

Painted exterior parts were installed and fender tips and trunk badge holes filled and smoothed. Preparation included checks underneath the car as well as the visible finish.

Balancing appearance and practicality.

Tire and wheel sizes were selected with front-to-rear rotation in mind. From the lowered photo setup, parts were removed and adjustments repeated to balance appearance and practicality.

Attention to the smallest details.

The rear registration-plate angle was corrected, and the front plate mounted on a bracket without drilling the visible surface. Small details are part of WORKS pre-owned car preparation.
