Parts for your 2008 Toyota Crown-Universal joints

2008 Toyota Crown universal joints (U-joints)

Based on technical references for the S200-series Toyota Crown (2008 model year)—including Toyota’s Electronic Parts Catalogue for the propeller shaft assembly, the Crown S200 Driveline/Propeller Shaft section of the workshop manual (TIS), and Aisin driveline design guides—the 2008 Toyota Crown uses cardan-type universal joints on the rear-wheel-drive propeller shaft (and on AWD variants, front/rear props). So universal joints are relevant and fitted to this model.

On this Crown, the U-joints let the propeller shaft transfer torque from the transmission to the diff while accommodating suspension movement and slight angle changes. Without them, the driveline would bind, vibrate, or fail prematurely. Many Toyota shafts of this era use sealed, non-greaseable cross-and-bearing U-joints with a centre support bearing on the two-piece shaft, keeping things smooth and quiet when they’re healthy.

As part of regular servicing of a 2008 Toyota Crown’s universal joints, it’s smart to check for early signs of wear every 20,000–30,000 km or if there’s any driveline vibration. Listen for a metallic click or clunk when shifting from Park to Drive/Reverse, feel for a buzz or shudder under load at 40–80 km/h, and look for rust bleed at the bearing caps or play at the yokes. Any free play or gritty movement when the shaft is articulated off the car points to a tired U-joint.

Replacement is straightforward for an experienced tech but needs care. Mark the flange relationships before removal to preserve balance, keep the yokes in phase during refit, and torque the flange bolts to spec with threadlocker where specified by Toyota. If the joint is the staked, non-serviceable type common on Toyota props, either press in a correct-size replacement with the right tooling or replace the complete propshaft/propeller shaft sub‑assembly to maintain balance and NVH standards. It’s also worth inspecting the centre support bearing and rubber coupler at the same time—if one part is worn, the others aren’t far behind.

If an aftermarket greaseable U-joint has been fitted, hit the zerk with a quality lithium-moly or NLGI #2 chassis grease at service intervals and after water crossings. After any U-joint work, a road test should confirm no vibration on light throttle and overrun. If a shimmy remains, get the shaft rebalanced.

How can someone tell their Crown’s U-joints are on the way out?

Common giveaways are a clunk taking up drive, a rhythmic vibration at highway speeds that changes with throttle, and rust-coloured streaks at the bearing caps. With the car safely lifted, any detectable play at the joint or a crunchy feel when the yoke is moved by hand means it’s time to replace.

Are the 2008 Toyota Crown’s U-joints serviceable or sealed?

Many are sealed, non-greaseable and originally staked in. They can be replaced with the correct tools and quality joints, but plenty of workshops opt for a complete prop shaft assembly to preserve balance. Some aftermarket replacements are greaseable—if so, add them to the lube schedule.

Should the centre support bearing be replaced with the U-joints?

Often, yes. If the rubber isolator is cracked or the bearing feels rough, doing it at the same time prevents a return visit for new vibrations and keeps the prop shaft aligned under load.
