Parts for your 2017 Toyota Mark x-Universal joints

2017 Toyota Mark X universal joints: what they do and how to look after them

Based on Toyota’s GRX130/133 Mark X driveline layout in technical service literature and typical parts catalogues for this platform, the 2017 Toyota Mark X uses a propeller (drive) shaft equipped with cross‑and‑bearing universal joints (U‑joints). Rear‑wheel drive and AWD variants both rely on universal joints to transmit torque while the shaft runs at slight angles, sometimes alongside a centre support bearing on a two‑piece shaft. So yes—universaljoints are relevant to the 2017 Toyota Mark X.

On this model, the universal joints let the prop shaft articulate as the rear suspension moves, keeping power delivery smooth from the transmission to the differential. They’re compact, robust, and well‑suited to the Mark X’s longitudinal layout, handling everyday commuting and open‑road kilometres with minimal fuss. Some trims may also use a CV joint or a flex coupling in the mix, but the cross‑type U‑joint remains a core part of the assembly.

For most owners, universal joints are “fit and forget” until wear shows up. Typical tell‑tales include a clunk when taking off or shifting from reverse to drive, a steady vibration at 60–100 km/h, a low‑speed squeak that changes with road speed, or a faint shudder on load. Any visible play at the yokes or rust‑coloured dust around the caps is a red flag.

• Inspection rhythm: have the prop shaft, centre bearing and universaljoints checked during routine servicing, especially every 20,000–40,000 km or before long trips.
• Serviceability: many Mark X U‑joints are sealed/non‑greasable from factory. If worn, they’re replaced rather than lubricated. Aftermarket greasable options exist if you prefer periodic greasing.
• Replacement best practice: use quality joints, renew circlips, and have the shaft phased and balanced by a driveline specialist. It’s also smart to assess the centre support bearing and flange bolts at the same time.

Left too long, a failing U‑joint can escalate into vibrations that fatigue the centre bearing, damage yokes, or stress the transmission output seal. Replacing early costs less than chasing driveline shake later. For owners who’ve lowered, raised, or otherwise modified suspension geometry, more frequent checks are wise because joint working angles change and wear can speed up.

Bottom line: if the 2017 Toyota Mark X is showing any driveline clunks or highway buzz, have the U‑joints assessed promptly. A tidy replacement restores that smooth, refined feel the Mark X is known for across Australia and New Zealand.

Popular questions about 2017 Toyota Mark X universaljoints

Does the 2017 Toyota Mark X have universal joints?

Yes. The Mark X uses a propeller shaft with universal joints to transfer torque to the rear differential. RWD and AWD variants both rely on U‑joints, some trims may pair them with a CV joint or a flex coupling, but U‑joints remain part of the assembly. If in doubt, a quick VIN‑based parts lookup or an under‑car inspection will confirm your exact setup.

How long do the U‑joints last, and when should they be replaced?

On a well‑kept Mark X driven on sealed roads, U‑joints can last a very long time, often well past 150,000 km. Replace them when you notice clunks on take‑off, steady speed vibrations, squeaks that rise with road speed, or any free play at the joint. It’s sensible to have them checked every service if you tow, drive on corrugations, or have suspension mods.

Can the Mark X U‑joints be greased, or are they sealed?

Factory joints are typically sealed and maintenance‑free. If a sealed joint wears, replacement is the fix. Aftermarket greasable universaljoints are available and suit owners who want periodic lubrication as part of servicing—just follow the supplier’s greasing intervals and use the correct high‑moly or lithium‑based grease specified for U‑joints.
