2004 Toyota Mark X CV Boots — What They Do and When to Replace

Technical sources confirm the 2004 Toyota Mark X uses CV boots. The Toyota Electronic Parts Catalogue (EPC) for GRX120/GRX125 lists “boot kit, drive shaft” for the rear axle on rear‑wheel‑drive models and for both front and rear axles on AWD variants. The Toyota Repair Manual (Chassis: Axle & Differential/Drive Shaft) details inspection and replacement of CV boots and joints, and the Toyota New Car Features (NCF) for the GRX120 series outlines its independent rear suspension with half‑shafts, which rely on CV joints protected by rubber boots. So yes—CV boots are fitted to this vehicle.

The Mark X uses flexible rubber CV boots to seal grease around each constant‑velocity joint and keep out water and grit. On rear‑wheel‑drive models they’re at the rear half‑shafts, on AWD versions they’re at all four corners. If a boot splits, the grease gets flung out and contaminants get in, which quickly chews out the joint. Left too long, that turns into clicks, shudders on acceleration, and an expensive driveshaft replacement.

As part of regular servicing, it’s smart to have the CV boots visually checked every service interval (around 10,000–15,000 km for most Aussie and Kiwi schedules). Look for fresh grease sprayed around the inner rear rims, the underbody near the diff, or the inside of the guards. Small surface cracks mean the rubber’s ageing—replace the boot before it tears. If there’s a split and the grease is dirty or the joint clicks, a new joint or complete shaft is the safer bet.

Quality boot kits come with new clamps and the correct moly grease—use those and make sure the clamps are crimped properly. On AWD front ends, ensure the hub nut is torqued to spec and the ABS sensor wiring isn’t stressed during the job. After refitting, a quick road test for noise and vibration is a must.

For RWD Mark X owners, both inner and outer rear boots deserve attention. Cars that do a lot of motorway kilometres or see coastal conditions can harden the rubber faster, so keep an eye out. Catching a tired boot early is cheap, waiting until the joint is noisy rarely is.

• Tell‑tales: grease fling on wheels/underbody, cracking rubber, clicking on turns (AWD), vibration on throttle.
• Best practice: inspect every service, replace boots proactively, replace the joint/shaft if contamination or noise is present.

FAQs

Does a 2004 Mark X have front CV boots?
RWD models have CV boots only on the rear half‑shafts. AWD variants have CV boots on both front and rear drive shafts, so there are four boots per axle set.

How often should CV boots be replaced?
There’s no fixed kilometre age—boots are replaced on condition. Have them inspected every service, swap them out at the first sign of cracking or grease leakage to avoid damaging the CV joint.

Can a torn boot be replaced without changing the whole driveshaft?
Yes, if the joint hasn’t run dry or ingested grit. If the boot failed for a while and the joint clicks or feels rough, replacing the joint or complete shaft is usually the better long‑term fix.
