2014 Toyota Mark X CV Boots: What They Do and When to Service Them

CV boots are indeed fitted to the 2014 Toyota Mark X (GRX130 series). The model is rear-wheel drive with independent rear suspension, and its rear half-shafts use constant velocity (CV) joints protected by rubber boots. This is documented in Toyota’s GRX130 Repair Manual under Drivetrain/Axle – Rear Drive Shaft (components and service procedures identify inboard and outboard CV boots), and reflected in the Toyota Electronic Parts Catalogue, which lists rear drive shaft boot kits for GRX130. Driveline design texts also note that RWD vehicles with independent rear suspension employ CV joints with protective boots on the driven axle.

On a 2014 Mark X, the CV boots’ job is straightforward: keep the special moly grease in, and keep water, dust, and grit out of the rear CV joints. That sealed, flexible barrier is what lets the rear suspension move up and down while the shafts spin smoothly. When the boots are healthy, the joints last ages. When they split, the grease flicks out, contaminants get in, and the joint can start clicking, grinding, or vibrating under load.

As part of regular servicing, it pays to give the rear CV boots a proper look. A quick visual every 10,000–15,000 km is smart, especially if the car sees gravel roads, coastal air, or hot summers. Tell-tales include fresh grease flung around the inner wheel, cracks in the rubber, or a damp, weeping boot. If a boot is torn or leaking, replace it promptly—waiting can turn a cheap boot job into a full CV joint or shaft replacement.

Good practice on a Mark X boot service includes:

• Using quality OE-spec or premium aftermarket boots with proper stainless clamps and the correct moly CV grease.
• Cleaning the joint thoroughly if the boot’s been open, if there’s pitting or audible clicking, plan for a joint or shaft replacement.
• Checking both inboard and outboard boots on each rear half-shaft, plus nearby seals and rear wheel bearings for contamination.

A competent workshop can usually do a rear boot in about 1.0–1.5 hours per side, a complete shaft swap is typically a bit longer. Keeping on top of CV boots helps avoid WOF or roadworthy headaches and keeps the Mark X driving as smoothly as it should.

Popular questions

Does the 2014 Toyota Mark X have front CV boots?
No. The Mark X is rear-wheel drive, so the front wheels aren’t driven and don’t use CV axles or CV boots. The boots you’ll be servicing are on the rear half-shafts, where the drive comes from the differential to the rear wheels.

How often should the CV boots be checked, and how long does replacement take?
A good rule is to inspect them at each service or roughly every 10,000–15,000 km. If a boot is cracked or leaking, replace it straight away. A rear boot replacement often takes around 1.0–1.5 hours per side, a full shaft change can be 1.5–2.0 hours depending on condition.

Is it okay to drive with a torn CV boot?
Only short, gentle trips to a workshop. A torn boot quickly lets grit and water in, which chews out the joint and can lead to clicking, vibration, and eventual failure. Sorting the boot early is far cheaper than replacing a damaged joint or shaft.
