Parts for your 2002 Toyota Rav4-Universal joints

2002 Toyota RAV4 universal joints (U‑joints): what they do and when to sort them

Technical sources including the Toyota RAV4 2001–2005 Repair Manual (propeller shaft section), Toyota Electronic Parts Catalogue for ACA2# 4WD variants, and common workshop references confirm this: a 2002 RAV4 with AWD/4WD is fitted with a rear propeller shaft that uses universal joints. Front‑wheel drive (2WD) models don’t have a prop shaft and therefore don’t use U‑joints, they rely on constant velocity (CV) joints in the front half‑shafts instead. So U‑joints are relevant to 4WD RAV4s, and not used on 2WD versions.

On 4WD models, the universal joints sit at each end of the propeller shaft running between the transfer output and the rear differential. Their job is to transmit drive while allowing the shaft to run at slight angles as the suspension moves and the driveline flexes. Think of them as the tough little hinges that keep torque flowing smoothly without binding.

Most factory RAV4 prop shafts of this era use sealed, non‑greasable U‑joints (Toyota often sells the shaft as a complete assembly), though aftermarket greasable joints are available. During regular servicing, a quick check goes a long way:

• Listen for a chirp or squeak at low speeds, a clunk on take‑off or shift, or a steady vibration around 60–100 km/h.
• With the car safely raised, feel for play at the yokes, there should be effectively none.
• Look for rust‑coloured dust at the caps or signs of dried‑out bearing needles.

If any of that shows up, it’s time to replace. It’s smart practice to do both U‑joints together and inspect the centre support bearing while you’re there. Mark the prop shaft and yokes before removal to maintain phasing and balance, use the right press tools, and torque fasteners to spec from the factory manual. If the original joints are staked and not designed to be serviced, either fit quality aftermarket replacements that suit or replace the complete shaft.

For routine care, have the driveline checked at normal service intervals (10,000–15,000 km). If the car tows, sees corrugations, or copes with beach work, inspect more often. For 2WD owners, U‑joints aren’t part of the picture, focus instead on CV boot condition and axle play up front.

Popular questions

Does my 2002 RAV4 actually have U‑joints?
If it’s AWD/4WD, yes — there are U‑joints on the rear propeller shaft. If it’s 2WD, there’s no rear prop shaft, so no U‑joints, the car uses CV joints on the front driveshafts only.

Can the factory U‑joints be greased?
Most OE RAV4 U‑joints of this vintage are sealed and not greasable. Some aftermarket replacements include grease nipples, which can extend life if serviced at each oil change.

How long does replacement take?
A competent workshop can usually inspect, remove, press in new joints, and refit in around 1.5–3 hours, depending on whether the joints are staked, corrosion is present, and if the centre bearing needs attention.
