Parts for your 2008 Toyota Mark x-Cv joint

2008 Toyota Mark X CV joint — fitment, purpose and service advice

Relevant technical sources confirm the 2008 Toyota Mark X uses CV joints. Toyota’s Electronic Parts Catalogue for the X120 series (GRX120/121 rear-wheel drive, GRX125 4WD) lists “shaft assy, rear drive (with joint)” for all models, and front drive shafts with CV joints for the 4WD “Four” variants. The Toyota New Car Features/repair literature for Mark X X120 describes inboard and outboard constant velocity joints on the independent rear suspension, and major parts catalogues list rear and (on 4WD) front drive shafts with CV joints by part number. So, CV joints are directly relevant on this model.

On the RWD Mark X, each rear half-shaft uses a pair of CV joints to let the wheels move up and down while still receiving smooth torque from the differential. On GRX125 4WD cars, the front axles add CV joints at each end as well. The whole point is to keep power delivery silky and vibration-free at varying angles, which suits the Mark X’s refined touring vibe.

For servicing, CV joints are mostly about their protective rubber boots and the special high-moly grease inside. If a boot splits, grease flicks out and grit sneaks in, and the joint can start clicking or grinding not long after. Sensible shops will check the CV boots and clamps every service interval, looking for cracks, grease spray around the inner rims, or torn rubber. Catching a split boot early means a boot-and-grease service, which is far cheaper than replacing the whole shaft.

• Common symptoms owners notice: a rhythmic click or knock on take-off, shudder or vibration on load, grease splatter near the wheel or underbody, or a dull clunk when shifting from reverse to drive.
• Good practice: inspect boots at each service or every 10,000–15,000 km, replace any perished boots, and use the correct CV grease and new clamps. After shaft work, ensure axle nuts are correctly torqued and re-staked.

When replacement is due, quality matters. OEM or premium aftermarket shafts/joints tend to run quieter and last longer. On higher‑kilometre cars, replacing both sides on the same axle can restore balance and reduce future visits. For 4WD Mark X models, remember there are front and rear CV joints to consider, for RWD, attention centres on the rear axle shafts.

Popular questions about 2008 Toyota Mark X CV joints

Does a 2008 Toyota Mark X have CV joints?
Yes. All RWD models have CV-jointed rear half‑shafts, and 4WD “Four” variants also have CV-jointed front drive shafts. The front of RWD cars steers but isn’t driven, so no front CV joints on those.

What are the tell‑tale signs a CV joint is failing on a Mark X?
Clicking or knocking on acceleration, vibration under load, and grease splatter near the wheels point to trouble. A torn boot is the usual starting point, so catching that early saves the joint.

Should the whole shaft be replaced or just the boot?
If the boot has only just split and the joint is quiet with no play, a boot kit and fresh grease is typically fine. If there’s noise, wear, or contaminated grease, a complete shaft or joint assembly is the smarter fix.
