Parts for your 2003 Mitsubishi Pajero-Control arms

2003 Mitsubishi Pajero Control Arms

Control arms are absolutely used on the 2003 Mitsubishi Pajero. The NM/NP series runs a double-wishbone front end with upper and lower control arms, and a multi-link rear with several control/lateral arms. This setup is detailed in the Mitsubishi Pajero (NM/NP, 2000–2006) Workshop Manual, Group 33A – Front Suspension, and Group 34 – Rear Suspension. The Mitsubishi ASA electronic parts catalogue for NM/NP chassis also lists front upper and lower control arm assemblies and rear lateral/trailing arms, while independent repair manuals (Gregory’s and Haynes) cover Pajero/Montero control arm bushings and ball joints for these model years.

On a 2003 Pajero, the control arms locate the hubs to the chassis and guide the suspension through its travel, keeping camber and caster where they should be. Bushes at the body side and ball joints at the knuckle end let the wheels move up and down without unwanted fore–aft or side–to–side slop. The result is stable steering, even tyre wear, proper braking feel, and a comfy ride whether it’s school runs or corrugations out in the wop-wops.

Because they cop big loads off-road and on rough chip, the arms, bushes, and ball joints are wear items. Tell-tale signs include:

• Clunks, knocks, or a dull thud over speed bumps
• Steering wander, shimmy, or vague turn-in
• Uneven or rapid inner/outer tyre wear
• Vibration under braking that isn’t a warped rotor

As part of regular servicing, it’s smart to inspect control arm bushes and ball joint boots every 20,000–30,000 kilometres, or after heavy off-road trips. Look for cracked, split, or oil-soaked rubber, torn boots, and any free play. A pry bar and a keen eye go a long way, but if there’s movement you can feel, it’s time for parts.

When replacing, consider these tips:

• Replace bushings or complete arms in axle pairs to keep alignment even.
• Torque pivot bolts at ride height to avoid preloading bushes and premature wear.
• Always book a wheel alignment afterwards, camber/caster and toe will shift.
• For touring and towing, quality OE-style rubber bushes keep NVH down, polyurethane can sharpen response but may add harshness.
• If a ball joint is integrated into the arm, swap the whole arm rather than pressing the joint, unless the manual specifies a serviceable joint.
• Stick to the workshop manual’s torque specs and procedures, and replace any single-use hardware.

Treated right, Pajero control arms will go the distance. Regular checks, fresh bushes/ball joints when needed, and a proper alignment will keep it tracking straight and protecting those tyres.

Popular questions about 2003 Mitsubishi Pajero control arms

How long do Pajero control arm bushes and ball joints usually last?
On sealed roads, many owners see 80,000–150,000 kilometres, but off-road work, corrugations, big tyres, and extra weight (bars, winch, drawers) shorten that. Inspect at each service and after tough trips, replace at the first sign of play or cracking.

Do I need a wheel alignment after replacing control arms?
Yes. Changing arms or bushes alters camber/caster and toe. A proper four-wheel alignment is essential to keep it driving straight, protect tyres, and restore steering feel.

Should I choose polyurethane or rubber bushes for my Pajero?
Rubber is quiet, compliant, and ideal for mixed daily and touring use. Polyurethane can sharpen handling and response, but it may add NVH and requires careful greasing. For serious outback travel and comfort, many stick with quality OE-style rubber.
