Ford Bronco Ii Radius Arm Hardware Kits

Ford Bronco Ii Radius arm hardware kits

Starting at $13.95, AutoBuffy stocks 1 radius arm hardware kits from MOOG for the Ford Bronco Ii. This kit replaces the bolts, bushings, washers, and nuts that secure the radius arm to the frame and axle. When these fasteners or bushings wear out, the front axle loses its precise fore-aft location, causing wandering, pulling, and accelerated tire wear.

Signs your Ford Bronco Ii needs new radius arm hardware

  • Front end wanders or drifts on straight, flat roads without input from the steering wheel
  • Clunking or knocking noise from the front suspension when hitting bumps or during braking
  • Visible rust, corrosion, or shearing on the radius arm mounting bolt or nut
  • Uneven or cupped front tire wear caused by the axle shifting under acceleration or braking
  • Steering pulls to one side, especially noticeable when you accelerate or decelerate
  • Loose or collapsed radius arm bushing visible on inspection — bushing appears cracked, torn, or extruded past its sleeve

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

The most important decision is whether you need just the fastener hardware — bolts, nuts, and washers — or a complete kit that also includes replacement bushings. Most mechanics recommend replacing bushings and hardware together since both wear at similar rates and labor overlap is high. Material grade and coating matter for off-road or rust-belt vehicles.

Replacing radius arm hardware on a Ford Bronco Ii

Moderate⏱ 1.5–3 hours per sideFloor jack and jack standsBreaker bar and socket setTorque wrenchBushing press or large C-clamp (if replacing bushings)Penetrating oil

Safely raise and support the vehicle, then support the front axle independently so it does not drop when the radius arm fastener is removed. Soak corroded hardware with penetrating oil well in advance to ease removal. After installing new bushings and hardware, torque all fasteners to the manufacturer's specified range — never leave them hand-tight — and have the front-end alignment checked before returning the vehicle to regular service.

Frequently asked questions

How much does it cost to replace radius arm hardware kits on a Ford Bronco Ii?
Parts start at $13.95 for a Ford Bronco Ii radius arm hardware kit at AutoBuffy. Add shop labor — typically one to two hours per side — and total repair cost will vary by location and whether bushings are included. Doing it yourself keeps the job close to the parts cost alone.
Can I replace just the bolt and nut, or do I need the whole radius arm hardware kit for my Ford Bronco Ii?
You can replace fasteners alone if the bushings are still in good shape — no cracking, tearing, or excessive movement. In practice, if the bolt has been loose long enough to cause symptoms, the bushing bore is often wallowed out too. Inspecting the bushing before ordering saves a second disassembly.
How long do radius arm bushings and hardware last on a Ford Bronco Ii?
Lifespan varies widely based on use. On a highway-driven vehicle in a dry climate, hardware and rubber bushings can last many years. Off-road use, frequent towing, road salt exposure, and loose fasteners that go unaddressed all shorten service life significantly. Inspect them any time the front axle is accessible.
Is replacing radius arm hardware on a Ford Bronco Ii something I can do at home?
Yes, with basic hand tools and a jack stand setup it is a manageable DIY job. The main challenge is breaking loose corroded hardware and properly supporting the axle during removal. Torquing the new fasteners to the manufacturer's specification range is critical — under-torquing is what causes premature wear and noise.
Will worn radius arm hardware cause my Ford Bronco Ii to fail an alignment?
Yes. The radius arm controls the fore-aft position of the front axle. Loose or collapsed hardware allows the axle to shift, which throws off caster and can move toe outside alignment tolerances. Always replace worn radius arm hardware before performing a front-end alignment — otherwise the alignment will not hold.
Do I need to replace the radius arm hardware on both sides of my Ford Bronco Ii at the same time?
It is strongly recommended. Both sides experience the same age, mileage, and corrosion exposure. Replacing only one side often results in the other failing shortly after, requiring a second round of labor. Matching hardware and bushings side-to-side also ensures balanced steering geometry and even wear going forward.
