2012 Toyota Mark X CV Joint: What It Does and When to Service It

Based on Toyota’s own technical information for the GRX13# series (Toyota Repair Manual and Electronic Parts Catalogue) and mainstream parts catalogues used by workshops, the 2012 Toyota Mark X is fitted with CV joints. Rear-wheel drive variants have CV joints on the rear half-shafts, and “Four” all-wheel drive variants add front CV shafts as well. So yes—CV joints are absolutely relevant to this model year.

On a 2012 Mark X, the CV joint’s job is to send engine torque to the wheels smoothly while the suspension moves and, on AWD cars, while the front wheels steer. Outer joints handle bigger angles (steering or wheel travel), while inner joints manage plunge (suspension compression and rebound). They rely on quality grease and a sealed rubber boot to keep everything protected.

When the boots split or the grease leaks, the joint runs dry and wears fast. Classic tells include a rhythmic click on acceleration or while turning (outer joints), a shudder under load, or grease splattered around the wheel or underbody. Leaving it too long can damage the hub or diff and turn a simple repair into a bigger bill.

Good servicing habits for a Mark X include:

• Inspecting CV boots at each service or every 10–15,000 km—especially if the car’s lowered or driven on rough roads.
• Replacing any boot that’s cracked, torn, or weeping before the joint gets noisy.
• Using the correct spec moly CV grease and new clamps when rebooting.
• Checking for play or notchiness with the car safely raised, any clunk or roughness calls for further inspection.

When it’s time to fix, many workshops fit a complete shaft assembly for speed and reliability. Rebooting is fine if caught early and the joint surfaces are still mint. On AWD variants, make sure the replacement has the right spline count and ABS tone ring style for your VIN. Always use new axle nuts and follow Toyota torque specs so the hub bearings stay happy.

Look after the boots and a Mark X CV joint can rack up big kilometres without drama. Catch issues early and it’s an easy win for smooth, quiet motoring.

Popular questions about 2012 Toyota Mark X CV joints

Does the 2012 Mark X have front CV joints?
RWD versions only use CV joints on the rear half-shafts. The “Four” AWD models add front CV shafts with outer and inner joints to handle both steering and suspension movement.

How long do the CV joints and boots usually last?
With intact boots, joints often last well past 150,000 km. Boots are the weak point—age, heat, and road grit can crack them earlier. Routine inspections keep small boot issues from turning into joint replacements.

Is it better to replace just the boot or the entire shaft?
If the joint is still smooth and quiet, a reboot with fresh grease is cost-effective. If there’s clicking, play, or pitting, a complete shaft assembly is the smarter, longer-term fix.
