Parts for your 2008 Toyota Blade-Universal joints

2008 Toyota Blade universal joints: what’s fitted and what to service

Based on Toyota technical references – including the Toyota Electronic Parts Catalogue for Blade AZE154/AZE156/GRE156 series, the E15# Auris/Blade repair manual, and Toyota drivetrain layouts widely used in this platform – the 2008 Toyota Blade is primarily front‑wheel drive and uses constant‑velocity (CV) joints on the front drive shafts, not cross‑type universal joints. However, Blade variants equipped with the factory 4WD system (notably AZE156) add a rear propeller shaft to drive the rear differential, and that shaft employs universal joints (U‑joints) and a centre bearing. So: on FWD Blades, U‑joints aren’t relevant, on AWD Blades, they are present on the prop shaft.

Why U‑joints aren’t used on FWD Blades: the front half‑shafts must transmit power while steering and moving through large suspension angles at a constant rotational speed. That’s exactly what CV joints are designed for, a traditional U‑joint would introduce speed fluctuation and vibration at those steering angles. Hence Toyota fits CV joints at the hubs and inner tripod joints at the transaxle, which suit the packaging and ride/handling targets of the Blade’s E15# platform.

If the car is an AWD Blade, those prop‑shaft U‑joints do important work. They let the long shaft change angle as the body and rear differential move, keeping the rear wheels driven smoothly. Over time, U‑joints can wear from lack of lubrication, moisture ingress, or simple age. Tell‑tales include a clunk on take‑off or when shifting from drive to reverse, a shudder or buzz at certain road speeds, chirping at low speed, and visible play at the prop‑shaft yokes. Some Toyota prop shafts use sealed, non‑greasable U‑joints that are staked into the yokes, service often means replacing the entire prop‑shaft assembly or having a driveline specialist fit quality replacement joints and re‑balance the shaft.

Good servicing habits for an AWD Blade’s U‑joints:

• Inspection every 20,000–30,000 km or annually: check for free play, dry or torn seals, rust bleed, and binding.
• If greasable joints are fitted (aftermarket), purge old grease until fresh grease appears at the seals.
• When removing the prop shaft, mark flange positions to maintain phasing and balance, refit to factory torque specs from the Toyota manual.
• Replace a noisy or loose joint promptly to protect the centre bearing and rear diff.

For most FWD Blades, focus on the CV joints and boots instead: keep the boots intact and free of splits, as a torn boot quickly ruins a CV joint. For AWD owners, a quick check for driveline play and noises during regular servicing will keep the U‑joints happy and the ride smooth across Aussie and Kiwi roads.

FAQs

Does my 2008 Toyota Blade have universal joints?
If it’s front‑wheel drive, no – it uses CV joints. If it’s the 4WD/AWD variant (commonly AZE156), yes – the rear propeller shaft uses U‑joints and a centre bearing. Check the build plate or look for a rear differential to be sure.

What are common signs a Blade’s U‑joint is failing?
On AWD models: a clunk when shifting between drive and reverse, vibration or shudder at certain speeds, chirping at low speeds, or visible play at the yokes. Any of these warrants an inspection before it damages the centre bearing or diff.

Can the Blade’s U‑joints be greased?
Factory Toyota prop shafts are often sealed and non‑greasable. Aftermarket serviceable U‑joints may be fitted by a driveline specialist, adding grease nipples for periodic maintenance.
