Parts for your 2014 Toyota Mark x-Driveshafts

2014 Toyota Mark X driveshafts

Driveshafts absolutely apply to the 2014 Toyota Mark X. Technical sources including Toyota’s New Car Features (NCF) for the GRX130/133/135 series, the Toyota Repair Manual, and the Toyota Electronic Parts Catalogue (EPC) list a two-piece propeller shaft with a centre bearing for the rear-wheel-drive layout, plus rear axle drive shafts (half-shafts). Some 250G Four variants add a front propeller shaft and front CV drive shafts for AWD. That confirms the Mark X is fitted with driveshafts as standard driveline hardware.

On the Mark X, the propeller shaft sends torque from the automatic transmission to the rear differential, while the rear drive shafts carry that torque to the wheels. On AWD models, extra shafts split power to the front. The setup is designed for smooth, quiet delivery of power, using universal joints (uni joints) and constant-velocity (CV) joints to cope with movement, and a centre bearing to support the prop shaft. Most joints are sealed-for-life, so condition checks matter more than routine greasing.

As part of regular servicing, it’s smart to inspect the driveshafts every 20,000–30,000 km or at each service if the vehicle tows, runs lowered suspension, or drives on rough roads. Checks should cover:

• CV boots for splits or grease fling
• Free play or notchiness in uni joints and the centre bearing
• Vibration on throttle or at highway speeds (often balance or bearing related)
• Clunk on take-off or when shifting from R to D (possible joint wear)
• Oil seepage at diff or gearbox flanges that can contaminate rubber components

When replacement is due, quality matters. Using OEM or equivalent-spec shafts keeps balance and NVH in check. Mark the flanges before removal so the shaft goes back in phase, renew flange bolts and self-locking nuts, and torque to the figures in the Toyota repair manual. If the centre bearing rubber is cracked or noisy, replace it with the shaft out. After refit, a short road test helps confirm there’s no vibration, if there is, re-check phasing and balance. While most Mark X uni joints and CVs aren’t serviceable individually, specialist driveline shops can rebuild or balance prop shafts if needed. Keeping the shafts tidy and the boots intact will help the Mark X stay smooth, quiet and drama-free for the long haul.

Popular questions

How often should the 2014 Mark X driveshafts be inspected?
Every 20,000–30,000 km is a good rule of thumb, or at each service if the car tows, is lowered, or sees rough roads. A quick look for torn CV boots, grease fling, or any play in the centre bearing pays off.

What are the common signs of driveshaft or CV joint issues?
Look for vibration on throttle, a shudder on take-off, clicking on turns (CV-related), clunks when shifting from R to D, and any visible boot damage or grease spray around the underbody.

Can the uni joints be replaced separately on a Mark X?
On most 2014 Mark X variants, the prop shaft’s uni joints are sealed and not designed as separate service items. If there’s wear, many workshops replace or professionally rebuild the prop shaft assembly and renew the centre bearing at the same time.
