Parts for your 2013 Toyota Mark x-Universal joints

2013 Toyota Mark X universal joints: what’s fitted and how to look after them

Universal joints are fitted to the 2013 Toyota Mark X. This rear‑wheel‑drive GRX13# series uses a two‑piece propeller shaft with cross‑type universal joints and a centre support bearing. That layout is shown in Toyota’s Mark X (GRX130/133/135) Repair Manual under Propeller Shaft and in the Toyota Electronic Parts Catalog (Driveline/Propeller Shaft, Group 37), which list the prop shaft assembly with U‑joints and the centre bearing.

On this model, the universal joints (often called U‑joints or spiders) let the prop shaft transmit torque while accommodating the slight angle changes between the transmission and the differential as the suspension moves. Without them, the driveline would bind, causing nasty vibrations and premature wear. The Mark X runs a two‑piece shaft to keep angles shallow and NVH low, with the centre bearing supporting the lot halfway down the tunnel.

Most factory Mark X prop shafts use sealed, staked‑in U‑joints. That means there are no grease nipples, and the joints aren’t designed to be serviced individually in a dealer setting, Toyota typically supplies the complete propeller shaft assembly if there’s excessive play or roughness. A good driveline specialist can often rebuild the shaft with replacement joints and then re‑balance it, which can be more cost‑effective on higher‑kilometre cars.

What owners should watch for during servicing:

• Shudder or vibration on acceleration or at 60–100 km/h.
• Clunk when shifting from reverse to drive or on take‑off.
• Rhythmic squeak or chirp that rises with road speed (often goes away when loaded).
• Visible rust dust at the bearing caps, or noticeable play when the shaft is twisted by hand.

At each routine service, it’s smart to check the prop shaft for play, inspect the centre bearing rubber, and look for leaking or dry bearing caps. If a joint is noisy or notchy when the shaft is articulated by hand, plan replacement before it lets go and damages the tunnel or exhaust. If the shaft is removed, always mark flange positions to maintain phasing, refit with threadlocker to the specified torque, and have the assembly balanced if any components are changed.

Drivers who tow, launch hard, or run lowered suspension may see faster U‑joint wear due to steeper operating angles. Keeping ride height sensible and replacing tired engine/gearbox mounts helps the universal joints live a long, quiet life.

Popular questions about 2013 Toyota Mark X universal joints

Do the 2013 Mark X universal joints have grease nipples?

Factory prop shafts on the GRX13# Mark X generally use sealed, staked U‑joints with no grease nipples. They’re built for long service life without routine greasing. Some aftermarket or rebuilt shafts can be fitted with greaseable joints, a driveline shop can advise and set that up if desired.

How long do the universal joints typically last?

On a well‑looked‑after Mark X driven on decent roads, U‑joints commonly last well past 150,000 km and often to 250,000 km. Longevity depends on operating angles, driving style, contamination, and the condition of mounts and the centre bearing. Any vibration or clunking should be checked early to avoid knock‑on damage.

Can the Mark X U‑joints be replaced without changing the whole shaft?

Toyota’s service approach is to replace the complete propeller shaft assembly. However, many driveline specialists can press out the staked joints, fit high‑quality replacements, and then re‑balance the shaft. That route can save money and add greaseable joints, provided the work is done by a reputable shop with proper balancing gear.
