Parts for your 2008 Toyota Mark x-Cv boots

2008 Toyota Mark X CV boots — what they are, why they matter, and how to look after them

Technical sources confirm CV boots are absolutely relevant to the 2008 Toyota Mark X. Toyota’s Electronic Parts Catalog for the GRX12# series (GRX120 rear‑wheel drive and GRX125 all‑wheel drive) lists OEM boot kits for the drive shafts, and the Toyota Mark X Repair Manual (Chassis – Drive Shaft/Axle sections) includes inspection and replacement procedures for drive shaft boots. Parts catalogues used by dealers and workshops also show rear drive shaft boot kits for RWD models and both front and rear boot kits for AWD “Four” variants, so this model definitely uses CV boots.

On a 2008 Toyota Mark X, CV boots are the tough rubber bellows that seal the constant‑velocity joints on the drive shafts. They keep high‑moly grease in and water, dust, and road grit out. For RWD Mark X variants, the boots live on the rear half‑shafts either side of the differential. On AWD “Four” models, you’ll find them up front as well, tucked behind the hubs. When a boot splits, grease gets flung around the inner guard or suspension and the joint starts running dry — that’s when clicks, clunks, and pricey repairs aren’t far behind.

As part of regular servicing, it’s smart for owners to have the CV boots inspected every service interval, or at least every 10,000–15,000 km. A quick look for fine cracks, splits at the folds, loose clamps, or any grease mist on the arms or underbody can save a lot of coin. If a boot is torn, replacement should be organised straight away, the joint can often be saved if it hasn’t ingested grit. Many shops will clean and repack the joint with fresh grease, then fit new inner and outer clamps with a quality boot kit that suits the GRX12# platform.

• Common signs it’s time: grease sprayed near the wheel or diff, clicking on turns (AWD fronts), vibration under load, or WOF/reg inspection fails for perished rubber.
• Good practice: replace boots in pairs on the same axle, use OEM‑spec grease, and re‑torque hub/axle fasteners to the workshop manual figures.
• Driving conditions matter: lots of gravel, floodwater, or coastal roads can age the rubber sooner — checking more often is worth it.

Looked after properly, the Mark X’s CV boots are a simple bit of kit that quietly protect expensive driveline hardware and keep the ride smooth and drama‑free.

Popular questions about 2008 Toyota Mark X CV boots

Does a 2008 Mark X have front CV boots?
RWD models don’t have front drive shafts, so no front CV boots there — only at the rear. AWD “Four” variants do have front drive shafts with inner and outer CV boots behind the front hubs, as well as rear boots.

How often should CV boots be checked or replaced?
Have them checked at each service or roughly every 10,000–15,000 km. Replace immediately if a boot is torn or clamps are loose. In normal use, intact boots can last years, but harsh roads, heat, and age can crack the rubber earlier.

What happens if a CV boot fails on a Mark X?
Grease escapes, contaminants get in, and the CV joint wears quickly. Left too long, it can progress from a light click on turns to vibration and full joint failure, turning a simple boot job into a complete driveshaft or joint replacement.
