Parts for your 2017 Ford Ranger-Ball joints

2017 Ford Ranger ball joints — what they do and when to replace them

Technical sources including the Ford Workshop Manual for the PX II Ranger (2015–2018), Ford’s genuine parts catalogue, and major aftermarket suspension catalogues all confirm the 2017 Ford Ranger runs front suspension ball joints. The Ranger uses a double wishbone front end with an upper and a lower ball joint locating the steering knuckle, while the rear is a leaf-sprung live axle with no ball joints.

On this ute, the ball joints act like heavy‑duty swivels. They let the front wheels steer left and right while the suspension moves up and down over bumps. That combination of steering load, braking force and suspension travel means the joints cop a hiding—especially with bigger tyres, towing, touring gear or long stints on corrugations.

From the factory, the upper ball joint is typically supplied as part of the complete upper control arm assembly, while the lower ball joint is serviceable separately and pressed into the lower arm. Many aftermarket options offer greasable joints or complete arms to suit. Most OE ball joints are sealed and maintenance‑free, once the protective boot tears or looseness appears, the fix is replacement.

• Common signs of wear: clunks over bumps, vague steering, uneven tyre wear on the shoulders, knocking during low‑speed turns, or a steering pull.
• Service tip: inspect boots and joint free play at every service or at least every 20,000 km—more often if it sees off‑road work, water crossings or heavy loads.
• Replacement advice: use quality parts, press tools and new fixings, follow the workshop manual procedures and torque specs, finish with a wheel alignment.

If a joint has measurable play or a split boot full of grit, it’s time. Many techs replace ball joints in axle pairs (both lowers, or both upper control arms) to keep steering feel and tyre wear even left‑to‑right. It’s also smart to check tie‑rod ends and control‑arm bushes at the same time, as they age together. After installation, an alignment is essential—camber and caster on the Ranger’s front end are sensitive to even small changes.

Treated well and checked regularly, the Ranger’s ball joints will keep the front end tight, tyres wearing neatly, and steering tracking straight—on bitumen, gravel or that next big lap.

Popular questions

How long do ball joints last on a 2017 Ford Ranger?
Service life varies with use and environment. Many stock Rangers see 80,000–150,000 km from original joints. Heavy towing, larger tyres, mining or outback work can shorten that. Regular inspections will catch wear before it chews tyres.

Can just one ball joint be replaced, or should they be done in pairs?
You can replace a single worn joint, but many workshops recommend doing them in axle pairs to keep steering feel and tyre wear even. Note the OE upper joint is commonly part of the upper control arm assembly, so that side is replaced as a complete arm.

Do you need a wheel alignment after replacing ball joints?
Yes. Any work on the control arms or knuckle can nudge camber and caster. A proper alignment after replacement protects tyres and restores straight‑line stability.
