Parts for your 2025 Mitsubishi Triton-Universal joints

2025 Mitsubishi Triton universal joints: what they do and how to look after them

Technical sources confirm the 2025 Mitsubishi Triton does use universal joints. The Mitsubishi Motors Triton/L200 Workshop Manual (2024–on, Group 22 – Propeller Shaft) specifies inspection of the propeller shaft universal joints for free play and noise, and the Mitsubishi ASA Electronic Parts Catalogue for the same generation lists universal joint components within the rear propeller shaft assembly. Australian driveline catalogues (e.g., Hardy Spicer application data) also show rear prop-shaft universal joint kits for current Triton models. Up front, the independent suspension uses CV joints, the universal joints are on the rear propeller shaft.

On a 2025 Triton, the universal joints sit at the yokes of the two-piece rear prop shaft, letting the shaft articulate as the suspension moves while still sending torque smoothly from the transmission/transfer case to the rear diff. They manage the changing driveline angles that come with load, towing and off-road articulation, helping prevent vibration and binding. In short, they keep the ute feeling tight and predictable under throttle.

Servicing-wise, it’s smart to check the universal joints at every scheduled service or about every 15,000 km, and sooner after deep water crossings, heavy towing, corrugations or beach work. Many late-model Tritons run sealed, non-greasable OE universal joints, aftermarket replacements may have grease nipples. If they’re sealed, don’t try to add lube—just inspect carefully. If they’re greasable, a couple of pumps of quality lithium-based grease at service time will keep the needles happy.

• Common warning signs: a metallic clunk on take-off, a chirp or squeak at low speed, shudder or vibration under load (often 60–100 km/h), red/rusty dust around caps, or any visible looseness at the yokes.
• If any play is felt, replace the joint promptly to avoid damage to the centre bearing, output seals or diff/transfer case.

1. During replacement, mark the shaft and yokes to maintain phasing, support the two-piece shaft so the centre bearing isn’t strained, and use proper circlip/press tools.
2. Torque the flange bolts to spec and check shaft balance, a rebalance is wise if a joint has failed badly.
3. After refit, road-test for vibration and recheck for any weeps at seals.

Treated right, Triton universal joints can go well past 150,000 km, but tough Aussie and Kiwi conditions can shorten that. A quick check each service saves headaches later.

Does the 2025 Triton use universal joints or CVs at the back?

It uses universal joints on the rear propeller shaft and CV joints up front. The rear UJs allow the shaft to work through changing angles as the suspension moves, while front CVs suit the independent front end and steering angles.

How often should the universal joints be serviced?

Inspect them at every routine service (around 15,000 km intervals) and after water crossings or heavy off-road work. Most factory UJs are sealed, replace if worn. Aftermarket greasable joints should be lubricated lightly at each service.

Can a worn universal joint cause other damage?

Yes. Prolonged vibration can punish the centre bearing, flog out flange bolts, and stress the transfer-case and diff seals or bearings. If there’s play, sort it early to avoid bigger bills.
