Parts for your 2020 Isuzu D-max-Universal joints

2020 Isuzu D‑MAX universal joints

Based on technical sources, universal joints are definitely relevant to the 2020 Isuzu D‑MAX. The Isuzu D‑MAX (RG, 2020–) Workshop Manual’s driveline/propeller shaft section specifies cross‑type universal joints on the tailshaft, and the Isuzu Genuine Parts Catalogue (propeller shaft group) lists universal joint kits for 4x2 and 4x4 variants. Major aftermarket catalogues for this model also list replacement U‑joints, confirming they’re fitted to the vehicle from factory.

On a 2020 D‑MAX, the universal joints (U‑joints) sit on each end of the tailshaft and, on many 4x4 models, on the front prop shaft as well. Their job is to let the shaft transmit torque even while the angles change with suspension movement or as the drivetrain articulates. That keeps the ute smooth on the highway and trustworthy on rough tracks—exactly what’s needed in Aussie and Kiwi conditions.

Servicing-wise, most factory U‑joints on this generation are sealed units without grease nipples. That means they’re low‑maintenance, but it also means once the bearings wear, they’re replaced rather than rebuilt. During routine services, it’s smart to check for tell‑tale signs:

• Light chirping or squeaking at low speeds that comes and goes with road speed
• A dull clunk when shifting from Drive to Reverse
• Vibration on take‑off or at steady cruise that wasn’t there before
• Rust‑coloured dust around the bearing caps or perished seals

If any of that shows up, get the tailshaft inspected. A tech will safely support the shaft, mark its phasing, and check for play by twisting the yokes in opposite directions. Any movement in the caps means it’s time for new joints. Replacement is straightforward for a trained workshop: the shaft is removed, circlips are taken out, caps are pressed, the new joint is centred and clipped, and everything’s reinstalled with correct torque on the flange bolts. On two‑piece shafts, the centre bearing and slip joint splines are checked at the same time.

For owners who do a lot of towing, beach work, or outback corrugations, stepping up to quality greasable aftermarket U‑joints can be a smart move. Otherwise, stick with regular inspections every service (or sooner if you notice new noises or vibes), keep the tailshaft balanced and correctly phased, and the D‑MAX driveline will stay happy for a long time.

Does the 2020 D‑MAX have greasable U‑joints from factory?

Most 2020 models are fitted with sealed, non‑greaseable U‑joints from new. That keeps servicing simple, but once the needle bearings wear, the joint is replaced as an assembly.

If you prefer periodic greasing—particularly for heavy towing or off‑road use—there are quality greasable aftermarket U‑joints that suit the D‑MAX and work well in harsh conditions.

What are the common signs a D‑MAX U‑joint is failing?

Listen and feel for a chirp or squeak at low speed, a clunk when going from Drive to Reverse, and new vibrations under load or at cruise. Rusty dust near the bearing caps or slack when twisting the yokes by hand are also red flags.

Catch it early and you’ll avoid damage to the yokes, centre bearing, or transmission/transfer case flanges.

How often should the universal joints be checked or replaced?

Have them inspected at every routine service. For heavy use—towing, beach work, water crossings, or lots of corrugations—ask for a closer look every 10,000–15,000 km.

There’s no fixed replacement interval, they’re changed when there’s play, noise, or roughness. After any replacement, confirm correct tailshaft phasing and bolt torque, then road‑test to verify the vibe is gone.
