Parts for your 1999 Toyota Crown-Universal joints

1999 Toyota Crown universal-joints

Universal joints are fitted to the 1999 Toyota Crown. Toyota’s Electronic Parts Catalog (EPC) for the S170 series (1999–2003) lists front and rear universal joints on the propeller shaft, and the Toyota chassis repair literature for the Crown includes inspection and replacement procedures for the propeller shaft U-joints and centre bearing. The steering intermediate shaft also uses a small universal joint. These factory technical sources confirm universal-joints are relevant to this model.

On the 1999 Toyota Crown, the prop shaft universal-joints (U-joints) let the shaft transmit drive from the gearbox to the diff even as the suspension moves and angles change. They keep the driveline spinning smoothly without binding, so the car accelerates cleanly and stays quiet on the motorway. When they wear, the Crown can develop a tell-tale clunk on take-off, a chirp or squeak at low speed, or a vibration that gets worse under load around 60–100 km/h.

Many Crowns left the factory with sealed (non-greasable) U-joints. That means there’s no regular greasing point, and once play or roughness shows up, the fix is replacement rather than lubrication. A good shop will check them during servicing by safely lifting the vehicle, chocking the wheels, and feeling for play at each joint while rotating the shaft. Any looseness, notchiness, or rust-coloured dust around the caps is a red flag.

• Maintenance tip: If aftermarket greasable joints have been fitted, give them a light pump of quality chassis grease at service intervals (every 10,000–15,000 km) and after deep water crossings.
• Replacement tip: Mark the prop shaft flanges before removal to keep the original phasing and balance. If the original joints are staked from factory, replacement may require either specialised driveline work to fit circlip-style joints or fitting a reconditioned shaft assembly.
• Good practice: Always inspect the centre bearing and rubber support at the same time, as a flogged-out bearing can mimic U-joint vibration.

For owners chasing smoothness, replacing tired U-joints makes a noticeable difference: less shudder on pull-away, quieter cruising, and reduced wear on the diff and gearbox output. Stick with quality parts, torque the flange bolts correctly, and get the shaft balanced if any components are changed. It’s a straightforward job for a driveline specialist and well worth doing before a minor vibration turns into a bigger bill.

Popular questions about 1999 Toyota Crown universal-joints

How often should the U-joints be checked on a 1999 Crown?
They’re worth a look at every routine service. With sealed OEM joints there’s no greasing to do, but a quick inspection for play, dry caps, or rust dust can catch issues early. If the vehicle tows or sees rough roads, shorten the intervals.

What are the common signs the U-joints are failing?
Owners typically notice a clunk when shifting from reverse to drive, a rhythmic squeak at low speeds, or a vibration that comes in under load and eases off when coasting. Any of these warrant a proper driveline check before more components wear.

Can just the U-joint be replaced, or does the whole shaft need doing?
It depends on what’s fitted. Factory staked joints often require specialist work to fit serviceable circlip-style replacements, or a reconditioned shaft can be supplied outright. If an aftermarket shaft with greasable joints is already there, the individual joint can usually be swapped easily.
