Parts for your 2018 Toyota Rav4-Universal joints

2018 Toyota RAV4 universal joints (universaljoints): what they are, whether they’re fitted, and how to look after them

Based on Toyota’s technical literature (Toyota Repair Manual – Drivetrain/Axle: Propeller Shaft, Toyota Electronic Parts Catalogue for 2016–2018 RAV4, and general service references such as Haynes for 2013–2018 RAV4), universal joints are relevant to 2018 Toyota RAV4 models with AWD only. Front‑wheel drive RAV4s don’t have a propeller shaft, so they don’t use universal joints, they rely on front CV shafts instead. AWD RAV4s do have a propeller shaft to the rear differential, and it uses cross‑type universal joints that are factory‑staked and generally supplied as part of the complete shaft assembly.

On AWD models, the universaljoints sit at each end of the propeller shaft and let the shaft transmit engine torque down the line while the driveline angles change with suspension travel and engine movement. They keep things smooth when the body rolls over corrugations, the rear subframe shifts under load, or the transfer case and rear diff aren’t perfectly aligned. When they’re healthy, there’s no play, no binding, and no drama—just quiet, steady drive.

Maintenance is straightforward because the factory joints are sealed and not greasable. As part of regular servicing, it’s smart to inspect the shaft for rust bleed around the bearing caps, check for axial or radial play at the joints, and road‑test for noises or vibration under load and on overrun. If a universaljoint is worn or notchy, Toyota’s documented repair approach is replacement of the propeller shaft assembly rather than pressing in new joints, as the OE joints are staked and not listed as separate service parts. Some driveline specialists can rebuild and balance the shaft with replacement joints, but that’s a workshop decision based on condition and cost.

• Typical symptoms of a failing universaljoint on a 2018 RAV4 AWD:
  • Clunk when shifting from reverse to drive or on take‑off
  • Shudder or vibration that ramps up with road speed
  • Chirp or squeak that changes with vehicle speed, not engine revs

• Service tips:
  • Inspect flange bolts and alignment marks, refit in the same orientation to avoid balance issues
  • Check the centre bearing (if fitted) and rear diff/transfer case seals at the same time
  • After any shaft work, ensure correct torque on flange fasteners and verify no contact with heat shields

There’s no fixed replacement interval—many owners see well over 150,000–250,000 km before attention is needed, depending on use, loads, and road conditions common across Australia and New Zealand. If the RAV4 is showing any of the above behaviours, it’s time for a proper inspection and, if required, a new shaft or a specialist rebuild.

Does a 2018 Toyota RAV4 have universaljoints?

AWD models do, FWD models don’t. The AWD’s propeller shaft to the rear differential uses universal joints, while the FWD layout relies only on front CV shafts and has no rear driveshaft at all.

Toyota’s Repair Manual and the EPC for this generation confirm that the AWD shaft is supplied as an assembly with non‑serviceable, staked joints.

Can the universaljoints be replaced on their own?

Toyota typically supplies the propeller shaft as a complete unit, so the dealer path is to replace the assembly. That’s often the quickest way to restore smooth running and balance.

A competent driveline shop may be able to rebuild the shaft with new joints and re‑balance it, which can be cost‑effective if the tube and splines are still in good nick.

What noises point to worn universaljoints on a 2018 RAV4 AWD?

A dull clunk when shifting into gear, a speed‑related vibration on the motorway, or a rhythmic chirp that isn’t tied to engine revs are the usual suspects. You might also feel a shudder under load up hills.

If those signs pop up, park it for a thorough check—catching a failing joint early can prevent collateral damage to the shaft, flanges, or seals.
