Acura TL Radius Arm
The Acura TL Radius Arm helps keep the sedan stable by restricting the movement of the front and rear wheels along the road. This allows drivers predictable handling. Mounted between the axle and chassis, this Radius Arm controls longitudinal forces. The wheels don't drift forward when braking or slide back under hard acceleration. Across TL generations, the basic single-link layout remains, but improvements to the Radius Arm include the use of lighter stamped steel and later aluminum to reduce unsprung mass without sacrificing strength. Earlier designs preferred a simple transverse shape, whereas later models showed a slightly wristed profile facilitating articulation for improved ride comfort. The only major distinction between the two designs is the angle of bend and the freedom of movement. Both styles have the common aim to transfer road shock into the frame rather than the cabin, and both use tough bushings to absorb vibration and maintain alignment. The fact that the Radius Arm in all Acura vehicles is secured with bushings means that any worn rubber in a Radius Arm will quickly manifest itself with clunking noises or wandering steering indicating the need for replacement. Keeping an Acura TL steady begins with a healthy Radius Arm that is kept light, stiff, and aligned. In short, regular inspection helps the Acura suspension maintain the feel of balance that TL owners expect from it.

Acura TL Radius Arm Parts Questions & Experts Answers
- Q: How to remove and install the front lower control arm and radius arm on an Acura TL?A:Only 2003 and earlier models are equipped with a radius rod, while on 2004 and later models, the manufacturer states to replace the control arm-to-subframe mounting fasteners when they are removed. Begin by loosening the front wheel lug nuts, raising the vehicle, placing it securely on jackstands, and removing the wheel. Next, remove the through-bolt and detach the damper fork from the lower control arm, followed by detaching the stabilizer bar link from the lower control arm. Remove the cotter pin from the castle nut on the lower ball joint stud and loosen the nut approximately one-quarter inch without removing it to prevent uncontrolled separation of components. Use a two-jaw puller or equivalent to separate the lower control arm from the ball joint in the Steering Knuckle, then remove the nut. For 2004 and later models, remove the pivot and mounting bolts from the inner end of the lower control arm before removing the arm. For 2003 and earlier models, remove the two radius rod bolts fastening the radius rod to the control arm, then remove the pivot bolt from the inner end of the control arm and take out the arm. To completely remove the radius rod, take off the mounting nut at the subframe while guiding the radius rod out of the large washers and bushings, noting a smaller washer that may be a shim for adjusting the caster angle for front wheel alignment, which should be returned to the same position upon installation. Hold the other end of the radius rod with a wrench if it rotates while removing the mounting nut. Installation is the reverse of removal, ensuring to raise the outer end of the control arm with a floor jack to simulate normal ride height before tightening the pivot bolt and mounting bolt for the control arm. Install a new cotter pin, use new control arm mounting fasteners on 2004 and later models, tighten all fasteners to the specified torque values, and use a new self-locking nut for installing the radius rod to the subframe if it was removed. Finally, tighten the wheel lug nuts to the specified torque and test-drive the vehicle, checking for any concerns regarding handling and wheel alignment, and have the front end alignment checked and adjusted if necessary.
