Parts for your 2006 Toyota Mark x-Cv joint

2006 Toyota Mark X CV Joint — Fitment, purpose and service tips

Yes, the 2006 Toyota Mark X uses CV joints. Technical sources including the Toyota Electronic Parts Catalog for the GRX12# series (2004–2009) and the Toyota Mark X Repair Manual (Drivetrain/Axle sections for Rear Drive Shaft and, on “Four” AWD grades, Front Drive Shaft) list shaft assemblies with constant velocity joints and associated boot kits. Parts diagrams for the GRX120/121 (RWD) show CV-jointed rear half-shafts due to the independent rear suspension, while GRX125 “Four” AWD variants use CV-jointed shafts at both front and rear. That confirms the CV joint is very much relevant to this model.

On the Mark X, the CV joint lets the driven wheels move up and down with the suspension and steer (front on AWD) while still receiving smooth power. The outer joint is typically a fixed Rzeppa type for consistent speed through large angles, the inner is a plunge (tripod/DOJ) joint that slides to take up suspension travel. When everything’s healthy, it’s quiet, vibration-free and tidy. When it’s not, they’ll often announce themselves with clicking on turns, a thrum or shudder under throttle, or grease flung around the inner guards from a split boot.

During regular servicing in Australia or New Zealand, a quick visual of the CV boots pays off. If a boot’s starting to crack, replace it and re-pack with the correct high‑moly CV grease before grit gets in and chews the joint. Once the joint clicks, a full joint or complete shaft replacement is usually the smart move. Many workshops prefer complete shaft assemblies for reliability and time, especially on higher‑kilometre cars.

• Inspect CV boots every service or 10,000–15,000 km, more often if driving on gravel or rough roads.
• Look for sling marks of grease, torn rubber, or loose clamps.
• Use quality boots and the specified grease, cheap kits don’t last.
• Torque hub/axle nuts to spec and replace staked nuts and cotter pins as required by the manual.

Rear‑wheel‑drive Mark X models have CVs on the rear shafts only, AWD “Four” variants add front CVs that work harder due to steering angles, so they’re the first to complain when boots fail. Either way, keeping the boots intact is the difference between a tidy, quiet commute and a costly shaft replacement. If there’s noise, vibration, or visible boot damage, get it checked promptly rather than waiting for a roadside drama.

Popular questions about 2006 Toyota Mark X CV joints

Does a 2006 Mark X have CV joints?
Yes. RWD models use CV‑jointed rear half‑shafts, AWD “Four” grades use CV joints at both front and rear. Toyota’s EPC and repair manual procedures list the relevant drive shaft and CV joint components and service steps for GRX12# models.

How long do CV joints or boots last on a Mark X?
With intact boots, joints can last well beyond 200,000 km. Boots typically age faster on cars driven on gravel or through standing water. Catch a cracked boot early, re‑grease and clamp it, and the joint can keep going for years.

Can someone keep driving with a clicking CV joint?
It’ll usually keep moving for a while, but it’s risky. A clicking joint is worn, it can worsen quickly and may fail under load. If it’s just a split boot, repair it now to avoid turning a simple boot job into a full shaft replacement.
