Parts for your 2018 Toyota Rav4-Control arms

2018 Toyota RAV4 control arms — what they do and when to replace them

Yes, the 2018 Toyota RAV4 uses control arms. Toyota’s workshop information for the Australian/NZ-spec RAV4 (ASA44R/ALA49 series) specifies a front MacPherson strut setup with a front lower suspension arm (control arm), and a rear multi-link layout that includes several control arms and links. Toyota’s Electronic Parts Catalogue for this model likewise lists front lower arms and multiple rear arms, confirming they’re very much part of the suspension package.

On a 2018 RAV4, control arms locate the wheels and let the suspension move in a controlled arc. Up front, the lower control arm ties the hub to the subframe via large rubber bushes and a ball joint at the knuckle. Out back, the multi-link arrangement uses several arms to manage camber and toe through the suspension’s travel. All of this keeps steering feel tidy, tyres wearing evenly, and the ride settled over corrugations and city potholes.

They don’t need regular replacement on a schedule, but they do deserve a look each service or at least every 20,000 km. The common wear points are the rubber bushes (cracking, tearing, oil-soaked) and the ball joint (play, split boot). In coastal parts of Aus and NZ, check for corrosion on arms and bolts too.

• Watch for clues: clunks on bumps or braking, wandering or pulling, shimmy through the wheel, and uneven tyre wear.
• If replacing an arm, it’s smart to do left/right as a pair to keep handling consistent.
• Always get a wheel alignment afterwards — the front and rear geometry can shift with fresh bushes.
• Torque the arm bolts at normal ride height to avoid pre-loading new bushes.
• Some fronts come with bushes pre-fitted, the lower ball joint may be separate — replace if worn and renew any one-time-use nuts/bolts as Toyota specifies.

For rear arms, note there are dedicated toe and camber links, disturbed adjusters will alter alignment, so mark positions if removing and plan for an alignment regardless. With decent roads and sensible loads, many RAV4 control arm bushes go well past 100,000 km, but harsh impacts can shorten their life. Keeping tyres correctly inflated and avoiding kerb strikes will help them last.

Does the 2018 RAV4 have control arms front and rear?

It does. The front uses a single lower control arm per side with a ball joint, the rear is a multi-link arrangement made up of several arms and links that control camber and toe. This is documented in Toyota’s workshop and parts information for the ASA44R/ALA49 series.

How long do control arm bushes typically last on a 2018 RAV4?

There’s no fixed interval. Many owners see well over 100,000 km, but rough roads, heavy loads, or fluid contamination can age bushes earlier. Inspect at each service for cracking, tears, or movement, and replace when noise, vibration, or tyre wear shows up.

Do I need a wheel alignment after replacing control arms?

Yes. Fresh bushes and any disturbed adjusters change geometry. A post-repair alignment sets camber, caster, and toe back to spec and protects your tyres. It’s especially important on the rear multi-link where toe and camber links are adjustable.
