Parts for your 2018 Toyota Crown-Driveshafts

2018 Toyota Crown driveshafts

Driveshafts are absolutely relevant on the 2018 Toyota Crown. Technical sources such as Toyota’s Global Newsroom release for the 15th‑generation Crown identify a rear‑wheel‑drive TNGA‑L layout, which uses a propeller shaft to the rear differential, while Toyota’s Electronic Parts Catalogue lists front and rear drive shafts (CV shafts) and a propeller shaft for RWD grades. On E‑Four hybrid variants, Toyota notes an electric rear axle that deletes the centre prop shaft, but these still use driveshafts at the front and rear wheels to transmit torque.

On a 2018 Crown, the driveshafts do the heavy lifting of getting power to the road. In RWD models, the transmission sends torque down a central propeller shaft to the rear differential, and from there, left and right rear CV shafts deliver it to the wheels. In E‑Four hybrids, the front transaxle drives the front wheels via CV shafts, and a separate electric motor at the rear uses short halfshafts to turn the rear wheels—no mechanical prop shaft in the middle. Either way, the CV joints and boots are the frontline parts that cop road grime, water and heat.

As part of regular servicing, it’s smart to inspect the CV boots every 10,000–15,000 km or at each service. Look for split rubber, grease spray on the inner rims, or dampness around the joints. On RWD grades, also check the prop shaft universal joints and centre support bearing for play, rust dust, or perished rubber. Any vibration on take‑off, droning at motorway speeds, clicking on turns, or a thump when shifting from reverse to drive are red flags worth investigating.

If a boot is only just torn, a quality boot kit and fresh high‑moly grease can save the shaft. If the joint has run dry or is noisy, replacing the complete driveshaft is usually the better fix. Use OEM or reputable aftermarket shafts, torque the hub nut to spec, and get a road test to confirm no shudder. For E‑Four hybrids, avoid disturbing high‑voltage cabling near the rear e‑axle, leave that to trained techs. After deep water crossings or gravel road work, add an extra visual check—catching a split boot early can save a costly shaft down the track.

• Watch for: grease flung onto wheels, clicks on full lock, vibration under load, or clunks on take‑off.
• Service tips: inspect boots and clamps, check prop shaft U‑joints/centre bearing (RWD), and road test after any work.

Popular questions about 2018 Toyota Crown driveshafts

Does the 2018 Toyota Crown have a centre driveshaft?
RWD versions do—there’s a propeller shaft running from the transmission to the rear diff. E‑Four hybrid variants don’t, they use an electric rear axle, so there’s no mechanical prop shaft, but they still have front and rear CV shafts at the wheels.

How long do the driveshafts and CV joints last?
With intact boots, they often run well past 150,000 km. Harsh roads, torn boots, or lifted suspensions shorten life. Regular boot checks and prompt boot replacement if split will massively extend joint life.

Can a torn CV boot be repaired, or does the whole shaft need replacing?
If caught early and the joint is quiet, a new boot and fresh grease is fine. If there’s clicking, roughness, or metal flake in the grease, replace the complete shaft to avoid repeat labour and noise.
