Product Overview
Hardrace Front Upper Negative Camber Arm Ball Joint RP-7104-BJ – Lexus IS XE10 / Toyota Altezza XE10
Hardrace sells this ball joint as a replacement part for its 7104 adjustable front upper negative camber arms. The 7104 arms are a popular way to add negative camber to the first-generation Lexus IS and Toyota Altezza. Like any ball joint, the one in the arm wears with mileage and track use. Fitting a fresh joint lets you keep your existing arms rather than buying a complete new kit.
What it is for
This part is only for Hardrace 7104 arms. It will not replace the original Toyota/Lexus upper arm ball joint, and it is not designed for other aftermarket camber arms. Check that your arms are genuine Hardrace 7104 units before ordering.

Fitment
The 7104 arm and this ball joint are listed for the Lexus IS XE10 (IS200 and IS300) and the Toyota Altezza XE10, model years 1998 to 2005. Because the arms are fitted in pairs, you will need two of these joints to refresh both sides at the same time.
Fitting advice
With the car on axle stands and the wheel off, separate the upper ball joint from the hub carrier, then remove the camber arm from the car. Before you strip the arm, measure or mark the adjuster setting so you can return to a similar camber figure, then swap the joint following Hardrace’s instructions. Refit the arm and tighten all fasteners to the specified torques. A full alignment is essential afterwards, because camber and toe will both have moved. If you are not confident pressing out joints, have a suspension specialist do the work.
