Parts for your 2006 Toyota Crown-Universal joints

2006 Toyota Crown universal joints: purpose, care and replacement

Yes, the 2006 Toyota Crown (S180 series – GRS18x/UZS18x/GRS183 i-Four) uses universal joints on its propeller shaft. This is documented in Toyota’s Crown S180 Repair Manual (Propeller Shaft/Drive Shaft section) and the Toyota Electronic Parts Catalog, which lists a “Spider Kit, Universal Joint” for these models. These sources confirm U‑joints are fitted to both rear‑wheel‑drive and i‑Four all‑wheel‑drive variants to manage driveline angles between the transmission and differential.

On this Crown, the universal joints let the shaft transmit torque while the rear suspension moves, keeping things smooth when the angles change. Typically there’s a U‑joint at the front and rear of the prop shaft, with a centre support bearing on two‑piece shafts. Correct phasing of the yokes is important, when set properly, the slight speed fluctuation of one joint is cancelled by the other, reducing vibration. For everyday driving, that means quiet take‑offs, less shudder under load and a driveline that feels tight and well‑sorted.

For servicing of your 2006‑toyota‑crown universal‑joints, most factory joints are sealed and don’t need routine greasing, but they still need inspection. Look for red dust around the caps, dried grease weep, cracked seals, or any play at the crosses. On road, a dull clunk when shifting between drive and reverse, a rhythmic vibration between 60–100 km/h, or a chirp/whirr that changes with speed are classic signs of wear. If your Crown has greaseable retrofit joints, give them a couple of pumps of a good NLGI #2 lithium complex grease at regular services, wiping excess to protect the seals.

• Watch for clunks on take‑up, speed‑dependent vibration, or visible cap movement.
• If replacing, mark the shaft and yokes for phasing and balance before removal.
• Use a quality spider kit, replace any stretched circlips and worn yokes.
• Torque flange bolts to spec and recheck after a short drive.
• Inspect the centre support bearing and slip joint while you’re there.

There’s no time‑based replacement interval, change the universal joints when symptoms appear or if free play/binding is found during a service. After fitting, a quick road test for noise and vibration, then a fastener re‑torque, keeps the driveline happy. These recommendations align with Toyota’s service literature and common driveline practice for the S180 Crown platform.

Popular questions

Does a 2006 Toyota Crown have universal joints or CVs on the prop shaft?
Most 2006 Crowns use cross‑type universal joints on the prop shaft, not CVs. Toyota’s S180 Repair Manual and the EPC list a dedicated universal joint “spider kit” for these models, covering both RWD and i‑Four AWD variants.

What are the tell‑tale signs my Crown’s U‑joints are worn?
Common clues are a clunk when selecting drive or reverse, vibration that follows road speed, chirping or squeaking at low speed, and visible play at the caps. Any rust‑coloured dust around the caps is also a giveaway of needle bearing wear.

Can I grease the factory U‑joints on a 2006 Crown?
Factory joints are usually sealed and non‑greaseable. If your car has aftermarket greaseable joints, service them at each oil change with an NLGI #2 lithium complex grease until fresh lube purges from the seals—don’t over‑pump.
