What the AI looks for in Automotive Replacement Chassis Radius Arms & Parts

Vehicle design
Radius arms are used mainly on solid-axle Ford trucks, Ford beam front ends and some Land Rovers. Confirm the arm style and the axle-end bushing type. Arm length and bushing design vary by platform.
Bushing condition
Replace the frame-end radius arm bushings when they are split or the arm moves visibly under load. Worn radius arm bushings are a common cause of wander and caster loss.
Lift correction
On lifted vehicles, use radius arm drop brackets or lift-specific arms to restore caster. Lifting rotates the axle and reduces caster, causing wander.
Caster on solid-axle Ford trucks
Check caster on solid-axle Super Duty trucks after a lift. Caster correction is available through offset bushings or adjustable arms. Low caster is a frequent trigger of steering oscillation on these trucks.
