2013 Toyota Mark X Control Arms – What They Do and How to Look After Them

Control arms are absolutely fitted to the 2013 Toyota Mark X (GRX130/133). Technical sources including the Toyota Repair Manual for the GRX130 series, the Toyota Electronic Parts Catalogue (EPC), and reputable aftermarket suspension catalogues (TRW, MOOG, Sankei 555) confirm a front double-wishbone layout with upper and lower control arms, and a rear multi‑link setup that uses multiple arms to locate the wheel.

On this model, the front upper and lower arms set and hold camber and caster while allowing the hub to move smoothly through its travel. Rubber or hydraulic bushes in the arms isolate noise and vibration, and ball joints give the steering and suspension their articulation without slack. At the rear, the multi‑link control arms manage toe and camber changes as the suspension moves, keeping the Mark X planted and predictable through corners and over bumps.

As part of routine servicing, it’s smart to inspect the control arms every 20,000 km or 12 months. Look for cracked or oil‑soaked bushes, torn dust boots, rust at bushing sleeves, or any play in ball joints. If bushes are perished or joints are loose, replace the affected arms or components. Many owners choose complete arm assemblies for simplicity and longevity, though quality bushes can be pressed in if you prefer. Always torque arm bolts at normal ride height to avoid preloading the bushes, and book a four‑wheel alignment after any arm or bushing work.

• Common signs of wear: clunks over bumps, vague steering on the motorway, steering pull or tramlining, uneven inner shoulder tyre wear, instability under braking, and vibration through the wheel.
• Best practice: replace side‑to‑side in pairs, use new one‑time nuts/bolts where specified, and choose OE or reputable aftermarket brands.

Lowering springs or big‑wheel/low‑profile tyre setups can accelerate bush wear, so shorten inspection intervals if the car’s modified or driven on rough roads. Where the lower ball joint is separate from the arm, assess it carefully, play or torn boots warrant replacement and can trigger a WOF/RWC fail. Keeping the Mark X’s control arms in good nick preserves tyre life, sharpens steering feel, and maintains the safe, composed ride the chassis is known for.

Popular questions about 2013 Toyota Mark X control arms

Does the 2013 Mark X have upper and lower control arms at the front?
Yes. The front suspension is double‑wishbone with an upper and a lower control arm per side. The rear is multi‑link, using several arms to control wheel motion and alignment.

How often should the control arm bushes be replaced?
There’s no fixed interval. Inspect every 20,000 km or annually. Many bushes last 80,000–150,000 km depending on roads, climate, and driving style. Replace if cracked, torn, oil‑soaked, or if there’s excess movement.

Can worn control arms cause tyre wear or WOF/RWC issues?
Definitely. Excess bush or ball joint play can cause inner shoulder wear, pulling, and instability. Significant wear can lead to WOF (NZ) or RWC (AU) failure. After any repair, get a quality wheel alignment.
