Parts for your 2008 Toyota Mark x-Driveshafts

2008 Toyota Mark X driveshafts — what they do and when to service them

Technical sources confirm that driveshafts are absolutely used on the 2008 Toyota Mark X. The Toyota Mark X GRX120/121/125 Repair Manual (Driveline/Axle), the Toyota Electronic Parts Catalogue (entries for Propeller Shaft & Universal Joint, Rear Axle Shaft, and Front Drive Shaft for AWD), and model overviews noting an FR or AWD layout all point to the same thing: every 2008 Mark X runs a propeller shaft (driveshaft) to the rear, with rear half-shafts, and AWD grades also add front CV driveshafts. So, yes—driveshafts are relevant and fitted to this vehicle.

On a rear-wheel-drive Mark X, the two-piece propeller shaft sends power from the transmission to the rear differential, while the left and right rear half-shafts (CV type) deliver torque to each wheel. AWD variants keep that setup and add front CV shafts from a transfer case/front diff to the front hubs. In plain terms, those shafts are the link that turns engine power into forward motion, and they’ve got to spin smoothly and stay well-lubricated to keep the car feeling tight and refined.

As part of regular servicing, it’s smart to give the driveshafts a once-over every 10,000–15,000 km (or each service visit). Look for cracked or greasy CV boots, play in the universal joints, a tired centre support bearing on the prop shaft, and any weeping at the diff or transmission flanges. Catching small issues early—like a nicked boot—can prevent CV joint wear and save a bundle.

Common warning signs worth booking in for:

• Vibration or shudder on take-off or under load
• Clunk when shifting from reverse to drive, or on throttle tip-in
• Rhythmic humming that grows with speed
• Clicking on turns (more common with CV joints)
• Grease flung around the underbody near a split boot

Replacement or repair depends on what’s worn. Torn CV boots can often be rebooted if the joint is still smooth, but noisy or rusty joints are best replaced as complete shafts. For the prop shaft, worn universal joints or a noisy centre bearing can be renewed, and the shaft should be rebalanced if it’s been apart. Always use quality parts, new flange bolts where specified, and torque to spec, if seals are weeping at the flanges, replacing them at the same time is a tidy idea. After any driveline work, a short test drive to check for vibration and noise is worth its weight in gold.

Does a 2008 Toyota Mark X have front CV shafts?

RWD grades don’t, they have a rear prop shaft and rear half-shafts. AWD grades do have front CV shafts in addition to the rear setup.

How do I know if my Mark X driveshafts need attention?

Listen and feel for vibration on acceleration, clunks on take-off, or clicking in turns, and check for split boots and slung grease. Any of those signs call for an inspection.

Can a split CV boot be fixed without replacing the whole shaft?

Often, yes. If the joint hasn’t run dry or gritty, a new boot and fresh grease can sort it. If the joint’s noisy or rough, replace the shaft assembly.
