Parts for your 2023 Mitsubishi Triton-Universal joints

2023 Mitsubishi Triton universal joints (UJ): what they do and how to look after them

Based on Mitsubishi Motors’ MR-series Triton/L200 service manual (Propeller Shaft/Group 22A) and the Mitsubishi ASA parts catalogue for 2019–2024 models, the 2023 Mitsubishi Triton uses cross-type universal joints on its propeller shaft. Most Aussie and Kiwi-spec dual-cab and club-cab variants run a two-piece shaft with a centre bearing, with UJs at the yokes. So yes—universal joints are fitted and absolutely relevant to this ute.

Universal joints let the Triton’s propeller shaft transfer torque from the gearbox or transfer case to the diffs while accommodating suspension movement and small angle changes. They’re the flexible link that keeps drive smooth even when the rear axle articulates off-road or the driveline isn’t perfectly in line. When they’re healthy, you don’t notice them, when they’re worn, you’ll hear and feel them.

During routine servicing, it’s smart to give the UJs a check. Many OE joints on late-model Tritons are sealed-for-life, so there’s no grease nipple, inspection is the go. A tech will look for rust-coloured dust around the caps, cracks in the seals, looseness in the caps, and any free play in the joint. They’ll also road test for driveline clunks on take-off, shudder under load, or a speed-related vibration that kicks in around 60–100 km/h.

If your Triton has aftermarket greaseable UJs, a quality NLGI 2 lithium complex grease is typical. Grease them every 10,000–15,000 kilometres, or sooner after river crossings, beach runs, or muddy trips. Pump until fresh grease purges past the seals, wiping away excess. After deep water, re-grease as soon as practical.

Replacement is straightforward for a pro: mark the yokes to preserve phasing, support the shaft to protect the centre bearing, and torque the flange bolts to spec. If a sealed OE joint is worn, replace the joint (or the whole shaft assembly if required). Keeping the phasing and balance marks aligned prevents new vibrations. While there, check the centre bearing and rear diff pinion flange for play—no point fitting fresh UJs to a flogged bearing.

Look after the universal joints and the Triton’s driveline will stay quiet, smooth, and ready for towing, touring, and the weekday grind.

• Common symptoms of worn UJs:
  • Clunk on take-off or shifting from drive to reverse
  • Vibration at highway speeds that changes with throttle
  • Squeak at low speed that rises and falls with road speed

Does the 2023 Mitsubishi Triton have universal joints?

Yes. The factory driveline uses cross-type UJs on the propeller shaft, confirmed by Mitsubishi’s MR-series service manual and ASA parts listings. Many variants run a two-piece shaft with a centre bearing and UJs at the yokes.

How often should Triton universal joints be inspected or greased?

Have them inspected at each regular service. If yours are sealed OE joints, inspection is the key. If you’ve got greaseable aftermarket UJs, grease every 10,000–15,000 km, and after water crossings, sand, or mud. More off-road time generally means more frequent attention.

What are the signs a Triton’s UJs need replacing?

Listen and feel for a take-off clunk, a cyclic squeak at low speeds, or a vibration that sits at certain road speeds. On the hoist, any play in the caps, rust dust, or torn seals are red flags. If you notice these symptoms, get it checked before it takes out the centre bearing or damages the flange.
