2006 Toyota Mark X CV boots: what they do and when to replace them

CV boots are absolutely relevant on the 2006 Toyota Mark X. Technical sources including the Toyota Electronic Parts Catalog (GRX120/GRX121 “Drive Shaft & Axle” diagrams), Toyota’s Repair Manual on TIS (Rear Drive Shaft, Front Drive Shaft for 4WD), and OEM parts listings commonly used by dealers and importers (e.g., catalogues that list “Boot Kit, Rear Drive Shaft” and “Boot Kit, Front Drive Shaft” for Mark X) all show rubber boot sub‑assemblies on the vehicle’s constant‑velocity joints. Every 2006 Mark X with independent rear suspension (RWD GRX120) runs CV joints and boots on the rear half‑shafts, the 4WD/awd GRX121 also has front drive shafts with CV boots.

On this Mark X, the CV boots seal special moly grease around the CV joints and keep water, grit, and road muck out. That lets the joints articulate smoothly through suspension travel and steering (front on AWD), delivering quiet, silky drive with no shudder or click. When a boot splits, grease gets flung onto the inner rim, control arms, or underbody, the joint runs dry, and wear ramps up quickly—turning into clicking on turns (front AWD) or clunks and vibration under load (rear, all models).

As part of regular servicing of a 2006 Toyota Mark X, it’s smart to inspect the CV boots at each service or roughly every 10,000–15,000 km. Pay close attention to the bellows near the small clamp where fine cracks start. If there’s even a pinhole or signs of grease spray, book a boot replacement straight away. Catching it early usually means a simple boot kit with new clamps and high‑moly grease, keep driving with a torn boot and the joint itself may need replacing.

• Look for: grease on inner wheels/tyres, a rubbery split, clicking on turns (AWD fronts), or a thump on take‑off (rears).
• Use quality stainless clamps and the specified moly CV grease when fitting boot kits.
• After any boot or shaft work, ensure clamps are seated, boots aren’t twisted, and all fasteners are tightened to workshop specs.

For RWD Mark X owners, checks focus on the rear boots, AWD owners should have both front and rear boots inspected. Given New Zealand and Australian road conditions—heat, UV, and the odd gravel run—proactive boot checks save money and keep the Mark X driving beautifully.

Popular question: Does every 2006 Mark X have front CV boots?

Not all of them. The RWD GRX120 has CV boots on the rear half‑shafts only. The 4WD/AWD GRX121 adds front drive shafts, so it has CV boots front and rear. If unsure, check the build plate or look for front drive shafts behind the front wheels.

Popular question: How often should the CV boots be inspected?

Have them checked at every service or about every 10,000–15,000 kilometres. If the car sees gravel roads, coastal air, or lots of heat, ask for a closer look more often. Early boot replacement beats buying a complete shaft later.

Popular question: Can just the boot be replaced, or is a whole driveshaft needed?

If the boot has torn but the joint hasn’t started clicking or binding, a boot kit with fresh grease and clamps is usually fine. If there’s noise, rust, or play in the joint, a complete driveshaft or CV joint replacement is the better call.
