Parts for your 2020 Toyota Rav4-Universal joints

2020 Toyota RAV4 universal joints — are they even a thing?

Short answer: for most 2020 Toyota RAV4 variants, universal joints (U‑joints) aren’t a relevant or serviceable part. That’s not guesswork — it aligns with Toyota’s own technical literature. The Toyota New Car Features (NCF) for the AXAA/AXAH series (2019–2021) details three driveline layouts: front‑wheel drive (FWD), hybrid e‑AWD (e‑Four), and mechanical AWD. The Repair Manual and Toyota Electronic Parts Catalogue (EPC) back this up by showing what’s actually serviceable in each case.

Here’s the practical wrap for the 2020 RAV4 line-up:

• FWD petrol models: No propeller shaft, so no U‑joints. Drive is via front half‑shafts with constant‑velocity (CV) joints.
• Hybrid AWD (e‑Four): The rear axle is driven by an electric motor, not a prop shaft. Again, no U‑joints in the vehicle.
• AWD petrol (Dynamic Torque/AWD with or without torque vectoring): There is a propeller shaft to the rear differential, but Toyota specifies it as a sealed assembly. The joints at each end are non‑serviceable (staked/welded or CV‑type couplings). The EPC does not list a separate “spider” or U‑joint kit — if a joint wears, the prescribed fix in the Repair Manual is replacement of the propeller shaft assembly.

Why Toyota doesn’t use serviceable U‑joints here comes down to NVH (noise, vibration, harshness), packaging, weight and lifetime maintenance. Sealed joints and CV‑type couplings reduce vibration and run whisper‑quiet, with no grease nipples and no periodic lubrication. That’s straight out of Toyota’s NCF and Repair Manual guidance for this generation.

What should an owner or tech actually look after? On AWD petrol models, inspections focus on the centre support bearing, prop shaft fasteners, and transfer/rear diff oil levels. Any thump on take‑off, shudder on overrun, or speed‑related vibration should be investigated for a worn centre bearing, imbalance, or joint play — and the remedy is replacing the propeller shaft assembly rather than swapping a U‑joint. On FWD and hybrid e‑Four models, attention stays on front CV boots, wheel bearings and mounts, as there’s simply no prop shaft or U‑joints aboard.

Handy tip: symptoms that feel like a “bad U‑joint” on a RAV4 are often front CV joint noise, cupped tyres, or a tired engine/trans mount. A proper road test and underbody check will save guesswork and keep the RAV4 riding sweet for many kilometres.

• Does a 2020 RAV4 have universal joints?
  FWD and hybrid e‑AWD models don’t. Petrol AWD models have a propeller shaft with non‑serviceable joints, so there’s no separate U‑joint to grease or replace.
• Can the U‑joint be replaced on its own?
  No. Toyota’s EPC and Repair Manual specify the propeller shaft as a complete assembly. If there’s joint play or vibration traced to the shaft, the fix is to replace the assembly.
• What symptoms mimic a bad U‑joint on a RAV4?
  Clicking from front CVs on full lock, tyre cupping causing a hum, or a thump from soft engine/trans mounts. On AWD petrol models, a worn centre support bearing can also feel like a U‑joint issue.
