Parts for your 2001 Toyota Crown-Universal joints

2001 Toyota Crown universal-joints: what they do and how to look after them

Relevant and fitted: The 2001 Toyota Crown (S170 series sedans and Majesta variants) uses a rear-wheel-drive propeller shaft with universal joints. Technical references that document this include Toyota’s S170 Crown workshop/repair manual (Propeller Shaft section showing a two-piece shaft with front and rear cross-and-needle universal joints and a centre support bearing), the Toyota Electronic Parts Catalogue (EPC) for S170 Crown models listing propeller shaft sub-assemblies and universal-joint/yoke components, and the UZS/JZS171 chassis workshop diagrams illustrating the driveline layout. These sources confirm universal-joints are used on this vehicle.

On a 2001 Toyota Crown, the universal-joints live at each end of the propeller shaft, allowing the shaft to transmit power from the gearbox to the diff while coping with suspension movement and driveline angles. When they’re healthy, the Crown feels smooth on take-off and at motorway speeds. When they’re tired, they’ll let you know with a rumbling vibration, a clunk as drive takes up, or a chirp/creak that changes with speed.

Most Crowns of this era came with staked, non-greaseable OEM universal-joints. That means there are no grease nipples and, once worn, they’re typically replaced rather than routinely serviced. Many owners either fit a complete new or exchange prop shaft, or have a driveline specialist press out the staked joints and install quality circlip-type replacements that are greaseable.

Good servicing habits help the universal-joints last. During scheduled services:

• Check for play: with the car safely raised, hold the shaft near each yoke and feel for any free movement across the joint.
• Listen and road-test: note any speed-related vibration under load or on overrun.
• Inspect seals and caps: look for rust-coloured dust, missing clips (on retrofit joints), or sling-out grease.
• Sight the centre bearing and support rubber at the same time, as a failing support can mimic U-joint issues.

If replacement’s needed, mark the flanges so the shaft goes back in the same orientation, keep the yokes in phase, and torque fasteners to the factory spec. Aftermarket greaseable universal-joints should be lubricated lightly at each service or about every 10,000 km—more often if the Crown sees dusty or wet conditions. A tidy driveline balance and fresh joints will bring the big Toyota back to its relaxed, whisper-quiet best.

Popular questions about 2001 Toyota Crown universal-joints

Do Crowns use universal-joints or CV joints on the driveshaft?
The 2001 Crown’s propeller shaft uses cross-type universal-joints at the front and rear yokes, not CV joints. Some Crowns use CV-style joints at half-shafts in IRS diffs, but the main driveshaft is U-jointed.

What are the classic signs my Crown’s universal-joints are worn?
Common giveaways are a clunk on take-up, a vibration that’s worst at 60–100 km/h, or a chirping/creaking noise that speeds up with road speed. Any visible play at the joint or rust-coloured dust around the caps also points to wear.

Can the factory universal-joints be greased, or do I need a new shaft?
Factory joints on many S170 Crowns are staked and non-greaseable. They’re replaced when worn—either with a full prop shaft or by having a driveline shop fit quality circlip-style, greaseable joints and then balancing the shaft.
