2010 Subaru Tribeca Control Arms — What They Do and How to Look After Them

Control arms are absolutely used on the 2010 Subaru Tribeca. Technical references including the Subaru factory service manual for the 2010 Tribeca (chassis/suspension sections), the Subaru Electronic Parts Catalogue, and major aftermarket catalogues (e.g., MOOG, Mevotech, Whiteline, Repco listings) all confirm fitment. The front suspension is a MacPherson strut setup with a lower control arm, while the independent rear uses a double-wishbone layout incorporating control arms/lateral links.

The Tribeca’s control arms keep each wheel precisely located as the suspension moves, so steering feels confident and tyre wear stays even. Up front, the lower arm links the subframe to the knuckle via bushes and a ball joint, letting the wheel travel up and down while holding camber and caster in check. Down the back, the double-wishbone arrangement uses arms and links to maintain stable geometry under cornering and braking. Rubber bushes soak up vibration and noise, the ball joint provides smooth articulation without slop. When the bushes crack or the joint loosens, the car can wander, clunk over bumps, or chew through tyres.

As part of regular servicing in Australia and New Zealand, it’s smart to inspect the Tribeca’s control arms every 10,000–15,000 kilometres, or at each service. Look for split or oil-soaked bushes, torn ball joint boots, and any excessive play. A quick pry-bar test on the bushes and a feel for joint movement with the wheel off the ground goes a long way. If wear’s found on one side, replacing arms in pairs helps keep handling balanced. An alignment is a must after any arm, bush, or ball joint work.

• Common signs they’re due: clunks on sharp bumps, steering shimmy under braking, pulling or tramlining, vague turn-in, and uneven or rapid tyre wear.
• Replacement tips: many aftermarket front arms come pre-fitted with bushes (and sometimes the ball joint), which saves press work. If reusing the arm, press-fit bushes and separate ball joints are available—just torque the pivot bolts at normal ride height to avoid twisting new bushes.
• Parts choice: quality OE or reputable aftermarket arms/bushes handle Aussie and Kiwi road conditions well. Expect lifespan to vary with road quality—coastal corrosion, big potholes, and heavy loads all shorten service life.

Done right, fresh control arm bushes and a tight ball joint restore that planted Subaru feel, protect those pricey tyres, and keep the Tribeca tracking straight for many kilometres.

Popular questions about 2010 Subaru Tribeca control arms

How do they know their Tribeca’s control arms are worn?
They’ll often notice clunks over speed bumps, a steering shimmy when braking from motorway speeds, or a pull that won’t disappear after a wheel balance. Uneven inner or outer tyre wear and vague steering are also classic giveaways. A technician can confirm by checking bush condition and ball joint play during a suspension inspection.

Is a wheel alignment needed after replacing control arms?
Yes, every time. Control arms directly affect camber, caster, and toe. Even if it “looks straight,” fresh bushes and any small geometry change will shift alignment. An alignment protects tyres and brings back proper steering feel.

Can they just replace the bushes instead of the whole arm?
Often, yes. If the arm itself isn’t bent or rusty, pressing in new bushes (and replacing the ball joint if worn) is a cost-effective fix. If multiple components are tired, or the arm is damaged, a complete arm with pre-installed bushes (and sometimes a ball joint) can save time and effort.
