Parts for your 1998 Toyota Crown-Universal joints

1998 Toyota Crown universal joints

Universal joints are absolutely relevant on a 1998 Toyota Crown. Technical references including the Toyota Electronic Parts Catalogue (EPC) for S150-series Crowns (circa 1995–2001), the Crown Repair Manual for these models, and Toyota’s New Car Features (NCF) literature describe a two‑piece propeller shaft with a centre support bearing and universal joints at the front and rear yokes. These documents outline inspection and service of the propeller shaft assembly, confirming that U‑joints are fitted from factory on rear‑wheel‑drive Crowns of this era.

On this model, the universal joints let the prop shaft transmit torque from the gearbox to the differential even as the rear suspension moves. That slight angular flexibility stops binding, reduces stress on the driveline, and keeps everything smooth under acceleration, cruising, and over bumps.

For servicing a 1998 Toyota Crown, it’s smart to include a U‑joint check at regular intervals (for example, every 20,000–30,000 kilometres or at each major service). Many factory joints on these cars are sealed and non‑greasable, so condition checks matter:

• Listen for squeaks at low speed, and clunks when shifting from reverse to drive or on throttle tip‑in.
• Feel for a vibration or shudder under load or at steady speeds (often 60–90 km/h).
• Inspect for rust‑coloured dust around the caps, dried grease trails, loose circlips (if fitted), or play in the joint when the shaft is twisted by hand.

If replacement is needed, note that some Crowns use staked, sealed joints. Those typically aren’t designed for on‑car servicing, the usual fix is either a full prop shaft replacement or having a driveline specialist machine out the stakes and fit quality circlip‑style U‑joints, then re‑balance the shaft. Aftermarket greasable joints are available for some variants, which can extend service life with periodic greasing.

When removing and refitting the shaft, always mark the flanges to keep the original balance and phasing, support the centre bearing correctly, and avoid dropping needle rollers out of the caps. If there’s still a vibration after new joints, have the centre support bearing and shaft balance checked. Safety‑wise, chock the wheels, support the vehicle solidly, and don’t run the driveline in gear on stands.

Done right, fresh universal joints restore that plush Crown driveline feel and protect the gearbox and diff from shock loads, which is exactly what owners in Australia and New Zealand expect from a tidy S150.

Does a 1998 Toyota Crown actually have universal joints?

Yes. The S150‑series Crown uses a two‑piece propeller shaft with a centre bearing and universal joints at the front and rear. Toyota’s EPC and Repair Manual for the series specify inspection and service of these joints as part of driveline maintenance.

What are the common signs the Crown’s U‑joints are worn?

Tell‑tales include a light squeak at low speeds, a clunk taking up drive, and a vibration under load or at highway speeds. Rust‑coloured dust near the caps or noticeable free play when twisting the shaft by hand also point to wear.

Can the Crown’s universal joints be greased, or are they sealed?

Many factory U‑joints on this model are sealed and non‑greasable. If they’re worn, replacement is the fix. Some rebuilds use circlip‑style, greasable joints, if fitted, a quick grease at each major service helps extend their life.
