Ford Bronco Ii Radius Arm Bushing Kits

Ford Bronco Ii Radius arm bushing kits

Starting at $11.95, AutoBuffy stocks 11 radius arm bushing kits from ACDelco, Dorman, and MOOG. Radius arm bushings isolate the rigid radius arm from the frame and axle, controlling fore-aft axle movement and absorbing road shock. When they crack or collapse, steering wanders, the front end clunks, and tire wear accelerates — problems that worsen quickly if ignored.

Signs your Ford Bronco Ii needs new radius arm bushings

  • Clunking or knocking from the front suspension during acceleration or braking, caused by the worn bushing allowing the radius arm to shift against metal
  • Steering wander or vague on-center feel — the axle shifts fore and aft under load instead of staying in a fixed position
  • Uneven or cupped front tire wear, especially on the inner or outer edge, from the axle moving out of its correct geometry
  • Vibration felt through the steering wheel at highway speeds that smooths out when you lift off the throttle
  • Visible cracking, tearing, or chunking of the rubber bushing material on inspection
  • Front end pulling to one side under hard braking as the radius arm shifts unevenly under deceleration load

Which radius arm bushing kit should you buy for your Ford Bronco Ii?

The main decisions are material — OE-style rubber versus polyurethane — and whether the kit covers both the frame-end and axle-end bushings or only one location. Full kits that address both ends restore geometry completely and are worth the small price premium over partial sets. Match the kit to your intended use: street driving, towing, or off-road, since each demands different stiffness levels.

OE Rubber Replacement

Replacing radius arm bushings on a Ford Bronco Ii

The radius arm must be unbolted at both the frame bracket and the axle to free it for bushing removal; support the axle independently before disconnecting the arm. Old bushings are pressed out and new bushings are pressed in flush, with polyurethane kits requiring grease packing before assembly. Torque all fasteners to the manufacturer's specification with the suspension at ride height — not at full droop — then schedule a front-end alignment before driving.

Frequently asked questions

How much does it cost to replace radius arm bushings on a Ford Bronco Ii?
Parts start at $11.95 for a Ford Bronco Ii radius arm bushing kit at AutoBuffy. Add shop labor — typically one to two hours of flat-rate time — if you are not pressing the bushings yourself. A hydraulic press is usually required, so total cost varies depending on whether you DIY or use a shop.
How long do radius arm bushings last on a Ford Bronco Ii?
OE rubber radius arm bushings typically last anywhere from 60,000 to 100,000 miles under normal conditions, though off-road use, heavy towing, and harsh climates shorten that range considerably. Polyurethane replacements generally outlast rubber by a wide margin and are worth considering if longevity is a priority.
Can I drive my Ford Bronco Ii with bad radius arm bushings?
Short distances are possible, but it is not advisable. Worn radius arm bushings allow the axle to shift under braking and acceleration, which directly degrades steering control and can make emergency maneuvers unpredictable. Continued driving also accelerates tire wear and can damage the radius arm itself, increasing the total repair cost.
Do I need a press to install radius arm bushings on a Ford Bronco Ii?
In most cases, yes. Radius arm bushings are an interference fit into a steel sleeve or bracket and require a hydraulic press or a heavy-duty bushing press tool to seat them properly. Some polyurethane kits use a split or bolt-together design that eliminates the need for a press, making them a practical DIY option.
Should I replace radius arm bushings in pairs on a Ford Bronco Ii?
Always replace both sides at the same time. If one bushing has deteriorated enough to cause symptoms, the opposite side is typically at a similar stage of wear. Replacing only one side leaves the suspension with unequal compliance, which can cause a pulling sensation and uneven tire wear — the same problems you were trying to fix.
Will new radius arm bushings require a wheel alignment on my Ford Bronco Ii?
Yes, a front-end alignment is strongly recommended after replacing radius arm bushings. The radius arm controls the fore-aft position of the front axle, so even small changes in bushing height or stiffness can shift caster and toe settings enough to cause pulling and accelerated tire wear. Budget for the alignment when planning the job.
