Parts for your 2017 Toyota Mark x-Control arms

2017 Toyota Mark X Control Arms

Based on technical sources, control arms are definitely fitted to the 2017 Toyota Mark X (GRX130). The Toyota Repair Manual (TIS) for GRX130 specifies a double‑wishbone front suspension using upper and lower control arms, while the rear is a multi‑link layout that incorporates multiple control arms. The Toyota New Car Features (NCF) document for the Mark X describes the same geometry, and the Toyota Electronic Parts Catalogue (EPC) lists front lower arm sub‑assemblies and several rear control arm assemblies for this model year. That makes control arms a relevant and important service item on this vehicle.

On a 2017 Mark X, the control arms locate the wheels precisely under load, keeping alignment settings stable through bumps, braking and cornering. Up front, the double‑wishbone design helps deliver crisp turn‑in and consistent tyre contact, while the rear multi‑link arms manage toe and camber to keep things planted. Each arm pivots on rubber or hydraulic bushes and, where applicable, ball joints—these wear items are what most owners end up servicing.

Owners who want their Mark X to drive tight and true should keep an eye on the arms and bushes as part of routine servicing. A quick visual and pry‑bar check every 20,000–30,000 kilometres goes a long way. Look for torn bushes, perished rubber, cracked ball joint boots and any witness marks from arm‑to‑subframe contact. If one side is worn, it’s smart to replace in pairs to keep handling balanced. After any arm, bush or ball joint work, a four‑wheel alignment is a must—otherwise tyres can scrub out in no time.

• Common signs it’s time: clunks over bumps, vague steering, shimmy under braking, uneven tyre wear, or the car tram‑tracking.
• Fit quality parts—genuine or reputable aftermarket—especially for front lower arms and rear toe/camber arms that see the most load.
• Torque all arm bolts at normal ride height to avoid pre‑loading bushes. Many self‑locking nuts are single‑use—replace them.
• If ball joints are integrated into the arm, replace the whole arm rather than just the joint.

For New Zealand WOF or Aussie roadworthy checks, fresh control arm bushes and tight joints often make the difference between a pass and a headache. Kept in good nick, the Mark X rewards with tidy steering feel, even tyre wear and confident road manners.

Popular questions about 2017 Toyota Mark X control arms

Does the 2017 Toyota Mark X have front and rear control arms?
Yes. The GRX130-series Mark X runs a double‑wishbone front end with upper and lower arms, and a multi‑link rear with several control arms. That means both ends have arms, bushes and ball joints that can wear and may need service over time.

How often should control arm bushes be replaced on a Mark X?
There’s no fixed interval—bush life depends on kilometres, road conditions and driving style. As a guide, have them inspected every 20,000–30,000 km. Many cars see bush replacement somewhere around 80,000–150,000 km, sooner if driven on rough roads or lowered.

Do control arms require a wheel alignment after replacement?
Absolutely. Any time arms, bushes or ball joints are changed, the car should get a four‑wheel alignment. It prevents premature tyre wear and keeps the Mark X tracking straight and true.
