Parts for your 2013 Toyota Mark x-Cv boots

2013 Toyota Mark X CV boots: what they do and when to replace them

Based on technical references—Toyota Mark X (GRX130) Workshop Manual (Drivetrain/Axle—Rear Drive Shaft), the Toyota Electronic Parts Catalogue (GRX130) rear axle shaft/boot diagrams, and Toyota New Car Features for the GRX130 platform—the 2013 Toyota Mark X is rear‑wheel drive with independent rear suspension and uses constant‑velocity (CV) joints on both rear half‑shafts. Those CV joints are protected by rubber CV boots. There are no front drive shafts on this model, so no front CV boots, but the rear boots absolutely apply to servicing the Mark X.

On the Mark X, each rear half‑shaft has an inboard and outboard CV joint, typically a tripod (inboard) and a Rzeppa‑style (outboard). The CV boots keep high‑moly grease in and road grit, water, and dust out, so the joints can articulate smoothly as the suspension moves and the wheels put power to the road. When a boot cracks or the clamp loosens, grease flings onto nearby components and the joint can run dry, wearing quickly and eventually clicking, shuddering, or binding under load.

As part of regular servicing, it’s smart to inspect the rear CV boots every service or roughly every 10,000 km. Look along the bellows for hairline splits, weeping grease around the clamp areas, or any sling marks on the lower control arms and underbody. Give the clamps a quick check for tension and rust. In New Zealand and Australia, a split or leaking boot can lead to a WOF/RWC defect, so catching it early saves a much bigger bill later.

• Grease splatter on the inner rim, control arms, or exhaust
• Cracks in the rubber bellows or loose clamps
• Clicking or knocking on acceleration or over bumps
• Vibration under load from worn CV joint
• WOF/RWC fail due to torn or leaking boot

Replacement is typically done as a boot‑only repair if the joint hasn’t been run dry. A quality boot kit includes the correct boot, new stainless clamps, and the right spec moly grease—use the full packet, and keep everything surgically clean. If there’s any joint roughness or metallic paste in the old grease, a complete half‑shaft replacement is the safer call. On reassembly, align the boot to the locating ribs, seat and crimp the clamps properly, and torque all fasteners to the Toyota spec from the workshop manual. If any rear suspension arms were loosened, have the rear toe and camber checked afterwards.

Does a 2013 Toyota Mark X have CV boots at the front?

No. The GRX130 Mark X is rear‑wheel drive, so there are no front drive shafts or front CV boots. The CV boots you’ll service are on the rear half‑shafts only.

How often should the CV boots be replaced on a Mark X?

There’s no fixed interval—inspect at each service. Replace a boot at the first sign of cracking, grease weep, or clamp looseness. Waiting until it splits can quickly damage the CV joint.

Can a torn boot be re‑greased and re‑clamped, or does the shaft need replacing?

If caught early and the joint’s still smooth, a boot kit with fresh moly grease and new clamps is fine. If there’s noise, play, or contaminated grease, go for a complete half‑shaft to avoid repeat labour and future headaches.
