Parts for your 2010 Toyota Mark x-Universal joints

2010 Toyota Mark X universal joints (U‑joints)

Based on technical references including the Toyota Repair Manual for the GRX130 series (Propeller Shaft section) and Toyota EPC illustrations for the 2010 Mark X, this model uses a two‑piece rear propeller shaft featuring a centre universal joint. The assembly is typically a sealed, non‑greaseable design with staked bearings, depending on variant, the front may couple via a flex disc and the rear may use a CV joint, but a U‑joint is present and relevant to driveline service.

On the Mark X, the universal joint lets the prop shaft transmit engine torque while the angles between the transmission and differential change with suspension movement. That bit of clever articulation is what keeps things smooth when the road gets lumpy, during hard launches, and over speed humps. When a U‑joint wears, it shows up as driveline vibration, a clunk when shifting from park to drive or reverse, or a shudder on take‑off.

For routine servicing, the factory U‑joints on the GRX130 are sealed and not designed for periodic greasing. The practical approach is inspection at regular service intervals—look for free play, rust‑coloured dust around the cups, cracked seals, or any binding. Many workshops check this every 40,000–60,000 km, or sooner if the car tows, is lowered, or sees rough roads, as steeper operating angles accelerate wear.

If replacement is needed, Toyota supplies the propeller shaft as an assembly because of the staked, non‑serviceable joints. A driveline specialist can often rebuild the shaft with quality serviceable U‑joints and then balance the assembly. When the shaft is out, it’s smart to assess the centre support bearing and replace flange bolts and self‑locking nuts. Correct phasing, alignment marks, and torque specs matter to avoid new vibrations after refit.

Owners chasing a forever-fix sometimes opt for a rebuild with greaseable U‑joints, accepting the small trade‑off of periodic greasing for longer life. Whether staying OE or going serviceable, keeping the prop shaft straight and balanced, using new hardware, and verifying rear diff and transmission mounts are healthy will keep the Mark X feeling tight and refined.

• Common symptoms: clunk selecting D/R, high‑speed vibration, take‑off shudder, squeak at low speeds.
• Checks: play at the joint, binding spots, torn seals, centre bearing noise or movement.
• Good practice: inspect every service, sooner after big pothole strikes or ride‑height changes.

Popular questions about 2010 Toyota Mark X universal joints

Does the 2010 Mark X use U‑joints or only CV joints?
The GRX130 Mark X uses a two‑piece prop shaft with a centre U‑joint. Some variants also have a flex disc at the front and a CV joint at the rear, but a universal joint is part of the assembly and is a normal service consideration.

What are the tell‑tale signs the U‑joint is worn?
Expect a dull clunk when selecting drive or reverse, a shudder off the line, or a cyclical vibration at road speed. A dry, chirping squeak at low speeds and rust‑coloured dust around the bearing caps are also common clues.

Can the Mark X U‑joints be greased?
The factory joints are sealed and not greaseable. If wear develops, the OE approach is replacing the shaft assembly. A driveline shop can rebuild the shaft with serviceable, greaseable U‑joints and re‑balance it, which many owners choose for long‑term upkeep.
