Parts for your 2017 Toyota Mark x-Driveshafts

2017 Toyota Mark X Driveshafts

Technical sources confirm the 2017 Toyota Mark X uses driveshafts. Toyota’s Repair Manual for the GRX13# series lists “Propeller Shaft Assembly” and “Rear Drive Shaft Assembly” in the Drivetrain/Axle section, and the Toyota Electronic Parts Catalogue shows a two‑piece propeller shaft with centre bearing, plus left/right rear drive shafts and CV joints. The 2017 sales brochure also specifies a front‑engine, rear‑wheel‑drive layout. Driveshafts are absolutely fitted to this model.

On the Mark X, the driveshaft set‑up is classic rear‑drive kit. A two‑piece propeller shaft runs down the tunnel from the 6‑speed auto to the rear diff, and a pair of rear drive shafts (half‑shafts) carry torque to each wheel. Universal (uni) joints and a centre support bearing keep the prop shaft smooth, while CV joints at the rear hubs allow suspension movement without losing drive.

The job of the driveshafts is simple but critical: transmit engine torque quietly and without vibration. When they’re healthy, the car feels planted and fuss‑free, with clean take‑offs and silky highway cruising. Because the steering axle isn’t driven, the Mark X benefits from tidy front‑end feel while the rear hardware does the heavy lifting.

As part of regular servicing, it pays to give the shafts a once‑over. Look for split or weeping CV boots, thrown grease, cracked centre bearing rubber, or any free play in the uni joints. Check flange bolts for tightness, dents in the tube, and rust at welds. On the road, note any shudder on take‑off, droning or vibration between 60–100 km/h, a thump on gear changes, or clicking from the rear on tight turns—these are classic signs the driveline needs attention.

If a boot’s torn but the joint is quiet, a prompt boot and grease service can save the shaft. Noisy or loose joints usually mean replacement. The propeller shaft is factory balanced, so always mark the flanges before removal and keep the phasing the same on refit. Many Mark X props use staked, non‑serviceable uni joints—if there’s play or rust bleed at the caps, replace the assembly. Centre the support bearing during install, use new self‑locking nuts where specified, apply threadlocker to flange bolts, and torque to the workshop spec. After a road test, recheck fasteners.

Prevention is easy: avoid belting the tunnel off‑road, keep tyres matched and pressures even, fix transmission or diff seal leaks promptly, and stick to regular inspections every 15,000 km or so. Treated well, the Mark X driveshafts will clock up big kilometres with no drama. A gentle launch also reduces shock through the uni joints.

Popular questions about 2017 Toyota Mark X driveshafts

Does the 2017 Toyota Mark X use CV joints or uni joints?
It uses both. The central propeller shaft typically runs uni joints and a centre support bearing, while each rear half‑shaft uses CV joints to handle suspension travel.

What symptoms point to worn driveshafts on a Mark X?
Tell‑tales include vibration at 60–100 km/h, shudder on take‑off, a thump on gear changes, clicking from the rear on tight turns, or grease flung around from a split CV boot.

How often should the driveshafts be inspected or replaced?
There’s no fixed replacement interval. A quick inspection every service (about 10–15,000 km) is sensible. Replace components if there’s play, noise, damaged boots, or failed bearings.
