2016 Toyota Mark X CV boots: what they do and how to look after them

CV boots are absolutely used on the 2016 Toyota Mark X. Toyota’s GRX130-series service literature (Rear Drive Shaft and Front Drive Shaft sections) and the Toyota Electronic Parts Catalogue for GRX130/133 (RWD) and GRX135 (AWD) list inner and outer constant‑velocity joints with corresponding boot kits. On RWD Mark X models, the CV boots live on the independent rear half‑shafts, on AWD variants, they’re fitted to both the front and rear drive shafts.

For this model, CV boots have one big job: keep high‑moly grease inside the CV joints and keep water, dust, and road grit out. They flex with suspension travel (and steering on AWD fronts), so the joints can transmit torque smoothly without binding. Healthy boots mean quiet, vibration‑free acceleration and long CV joint life—exactly what a tidy Mark X should deliver.

As part of regular servicing, it’s smart to inspect the boots every time the car’s on a hoist—think every 10,000–15,000 kilometres, or at each oil change. Look for fine cracks, splits near the bellows, loose or rusty clamps, and slung grease on the inside of the wheels or underbody. Catching a boot early saves the joint, once grit gets in, wear accelerates and the fix often becomes a complete shaft replacement instead of a simple boot and grease job.

Replacement is straightforward for a trained tech: remove the shaft, clean the joint, repack with the specified moly CV grease, slip on the new boot, and crimp new stainless bands to spec. Quality matters—use genuine or OEM‑quality thermoplastic boots and the correct grease volume to avoid heat and premature cracking. If there’s any notchiness, clicking on turns (common at the front on AWD) or a thrum on acceleration, the joint itself may already be worn and should be assessed before just fitting a new boot.

• RWD Mark X: two rear shafts, each with inner and outer boots (four boots total).
• AWD Mark X: front and rear shafts—expect eight boots in total.
• Driving on gravel, coastal roads, or through floodwater? Inspect more often.

Bottom line: boots are cheap insurance. Keeping them intact preserves the CV joints, keeps the ride smooth, and avoids bigger bills down the track.

Popular questions about 2016 Toyota Mark X CV boots

Does a 2016 Mark X actually have CV boots?
Yes. RWD models use CV boots on the rear half‑shafts, AWD models have them front and rear. This layout is confirmed in Toyota’s GRX130‑series workshop procedures and the parts catalogue, which list boot kits for the relevant shafts.

How often should the CV boots be checked or replaced?
There’s no strict replacement interval—inspect at every service (about 10,000–15,000 km). Replace a boot as soon as cracks, splits, or grease flinging are found. In harsh Aussie and Kiwi conditions—heat, UV, gravel—more frequent checks are a good idea.

What are the signs a CV boot or joint is failing?
Grease sprayed around the wheel or underbody, visible splits in the boot, clicking while turning (AWD fronts), or a vibration under load. If contamination has occurred, the joint may need replacing, not just the boot.
