Parts for your 2007 Toyota Mark x-Cv joint

2007 Toyota Mark X CV Joint — what it is and when to sort it

Based on technical references, the 2007 Toyota Mark X does use CV joints. Toyota’s Electronic Parts Catalogue for GRX120/GRX121 (RWD) lists rear drive shafts with inboard/outboard CV joints, and the GRX125 (4WD “Four”) lists front and rear drive shafts with CV joints. The Toyota Mark X Repair Manual (GRX12#, Drivetrain/Axle sections) details CV joint and boot service, noting Rzeppa-type outers and tripod-type inners. The New Car Features (GRX12#) also outlines the 4WD system using front shafts with CV joints. So, a CV joint is absolutely relevant on this model.

On a 2007 Mark X, the CV joint’s job is to send power through the drive shafts while the suspension moves, keeping things smooth and quiet. RWD models use CV joints on the rear half-shafts, AWD “Four” models add CV joints up front as well. Each joint sits under a rubber boot packed with moly grease. If that boot cracks or a clamp loosens, grease escapes, water sneaks in, and wear kicks off fast.

As part of regular servicing, it’s worth a look under the guards for any fling of dark grease, cracked boots, or loose clamps. A quick wipe and inspection each service interval (10,000–15,000 km) can save a pricey axle later. If a boot’s just split and the joint’s still quiet and smooth, a reboot with fresh grease is often the best-value fix. If there’s clicking on turns (front on AWD), shudder on take-off, or noticeable play when twisting the shaft by hand, it’s time to consider a joint or complete shaft replacement.

For parts, stick with boot kits and grease that match the GRX12# spec, and ensure the replacement shaft matches length and ABS tone ring requirements. On reassembly, follow Toyota’s torque specs and nut-staking procedures from the Repair Manual, and take care around the ABS sensors and tone rings. With intact boots and quality clamps, Mark X CV joints commonly run well past 200,000 km.

• Tell-tale signs: clicking on lock, vibration under load, grease around the wheel/underbody, or clunks when shifting from drive to coast.
• AWD owners: front boots live in more heat and road splash, so keep a closer eye on them.

Popular questions

Does a rear-wheel-drive 2007 Mark X have CV joints?
Yes. RWD models use CV joints on the rear half-shafts. Only the AWD “Four” models have front CV axles as well.

How often should CV boots be replaced on a Mark X?
They’re not a timed item. Inspect at every service. Replace the boot as soon as you see cracking or grease leakage to protect the joint.

Is it safe to drive with a clicking CV joint?
Not ideal. Short trips to the workshop are usually fine, but a failing joint can worsen quickly and may let go under load.
