Parts for your 2017 Nissan Pulsar-Control arms

2017 Nissan Pulsar control arms — what they do and when to replace them

Based on technical sources — including the Nissan Pulsar (C13) factory service manual (Front Suspension “FSU” section) and common parts catalogues from major suppliers — the 2017 Nissan Pulsar runs a MacPherson strut front end with lower control arms (often called the lower link or wishbone). The rear of the C13 uses a torsion beam axle (see “RSU” rear suspension), so there aren’t traditional multi‑link control arms at the back. That means control arms are absolutely relevant on the front of a 2017 Pulsar.

On the front of the Pulsar, each control arm locates the wheel hub and keeps it tracking straight while the strut handles the up‑down movement. The arm pivots on rubber (often hydraulic) bushes at the subframe and connects to the steering knuckle via a ball joint. Together, they set alignment, absorb bumps, and keep the steering feel tidy. Most quality replacement arms for this model are supplied complete with bushes and ball joint, which makes installation cleaner and more reliable.

Typical signs the Pulsar’s front control arms or bushes need attention include:

• Clunks or knocks over speed humps and rough roads
• Steering shimmy or vibration under braking
• Uneven or rapid inner/outer tyre wear
• Wandering or tramlining at highway speeds

There’s no fixed replacement interval, but a good rule of thumb is to inspect at each service and more closely every 20,000–30,000 km. Aussie and Kiwi roads, hot summers, and the odd gravel shortcut are tough on front bushes, so expect many cars to need arms or bushes somewhere between 80,000 and 150,000 km.

When replacing, most workshops prefer swapping the complete arm. It’s faster, restores factory geometry, and avoids press-fit headaches. Always torque the arm bolts at normal ride height to prevent bush pre-load. Fresh hardware is a smart move if specified, and a four‑wheel alignment is a must afterwards to protect tyres and keep the steering sharp. If one side is gone, doing both sides helps keep braking and steering behaviour even.

For WOF or rego checks, any torn bushes, leaking hydro-bushes, or loose ball joints will usually be a fail item. Don’t ignore noises — leaving it too long can chew out tyres and strain other front-end parts.

Popular questions

Does the 2017 Pulsar have rear control arms?
Not in the usual sense. The rear is a torsion beam setup, so it doesn’t use separate multi‑link control arms. The front has the control arms.

How long do Pulsar control arm bushes and ball joints last?
There’s no set lifespan. Many owners see 80,000–150,000 km depending on roads and driving style. Inspect regularly and replace at the first signs of clunks, free play or uneven tyre wear.

Do you need a wheel alignment after replacing control arms?
Yes. Any time the control arms come out, the front alignment can shift. A professional alignment protects tyres and restores straight‑line stability.
