2021 Toyota LandCruiser CV boots: what they do and how to look after them

CV boots are absolutely used on the 2021 Toyota LandCruiser. The Toyota factory Repair Manual (TIS) for the 200 Series (URJ/VDJ202) and the first-year 300 Series, along with the Toyota Electronic Parts Catalog, specify front drive shafts with inboard and outboard constant velocity joints protected by rubber boots. These documents also include regular inspection steps and list boot kits for service, confirming their relevance to the 2021 LandCruiser.

On a 2021 LandCruiser, the front end uses independent suspension with CV shafts to deliver power to the front wheels while allowing steering and suspension travel. The CV boots are the flexible rubber covers on each end of the front drive shafts. Their job is simple but critical: keep high-moly CV grease in and keep grit, water, and mud out. When a boot splits or clamp tension drops, grease slings out and contaminants rush in, quickly wearing the joint. Left unchecked, that can turn into clicking on turns, vibration under load, or a full-blown CV failure—never fun, especially if you’re a long way from home.

Best practice is to have the boots inspected at every service (typically 10,000–15,000 km) and after heavy off-roading, mud, or water crossings. The Toyota workshop procedures call out checking for cracks, perishing, loose clamps, and any sign of grease spray around the inner guards, control arms, and wheel hubs. If a boot is torn but the joint hasn’t been run dry, a boot-only replacement with the correct Toyota-spec grease is the economical fix. If there’s clicking, corrosion, or play in the joint, a complete shaft or joint replacement is the safer route.

When replacing boots, use the correct inboard/outboard boot kits and greases (they’re not always the same), fit quality clamps with the right crimping tool, and torque the hub/axle fasteners to spec. After reassembly, a quick road test for noise and a check for any fresh grease mist is wise. Owners who tour or 4WD a lot may also choose proactive replacement of ageing boots before a big trip.

• Common signs: grease flung on the inner wheel or underbody, rubber splits or perishing, clicking on full lock, shudder under acceleration.
• Tip: After deep mud or beach work, rinse the area gently and recheck the boots once dry.

Popular questions about 2021 Toyota LandCruiser CV boots

How often should CV boots be replaced on a 2021 LandCruiser?

There’s no fixed kilometre interval. Inspect them every service and after hard off-road use. Good boots can last well past 100,000 km, but heat, age, UV, and off-road grit can shorten their life. Replace as soon as cracks, leaks, or loose clamps are found to protect the CV joints.

Can you drive with a torn CV boot?

It’s risky. A small split can quickly dump grease and let in sand and water, accelerating joint wear. If the boot just failed and the joint isn’t noisy, a prompt boot-only repair can save the CV. If there’s clicking or contamination, plan on a joint or shaft replacement.

Do both front CV boots need doing at the same time?

Not always, but many techs recommend replacing the opposite side if wear and age are similar. If one boot has perished, the other may be close behind—doing both can save a second visit and keeps the service timeline tidy.
