Parts for your 1999 Toyota Rav4-Universal joints

1999 Toyota RAV4 universal joints: what they do and how to look after them

Based on Toyota’s factory repair literature for the first‑generation RAV4 (1996–2000) and the Toyota Electronic Parts Catalog, universal joints are fitted to 1999 RAV4 models equipped with AWD/4WD. They’re located on the rear propeller shaft between the transfer case and rear differential, with a centre support bearing in between. Front drive shafts use constant‑velocity (CV) joints, not U‑joints. On front‑wheel drive (2WD) models there’s no rear propeller shaft, so universal joints aren’t used. Reputable sources include the Toyota RAV4 Repair Manual (Driveline/Axle – Propeller Shaft section) and mainstream workshop guides such as Haynes covering 1996–2010 RAV4.

For AWD owners, the universal joint (also called a Cardan joint) allows the prop shaft to transmit torque even as the angles change with suspension movement. It’s a simple cross and bearing setup that keeps drive smooth to the rear diff while the body and driveline move over bumps and through cornering. When healthy, it’s quiet, vibration‑free and basically invisible to the driver.

Servicing on many RAV4s is straightforward: the OE prop shaft assemblies typically run sealed, non‑greasable U‑joints. That means no routine greasing nipples to hit at each service. Instead, the smart play is regular inspection—ideally every 20,000–30,000 kilometres or at each scheduled service if the vehicle sees beach work, outback tracks, or plenty of rain and grit. A mechanic should check for red rust bleed around the bearing caps, any free play, binding when the shaft is articulated by hand, and condition of the centre support bearing and its rubber.

Tell‑tale symptoms of worn U‑joints include a clunk on take‑off or shift from drive to reverse, a droning or buzzing vibration that changes with road speed (not engine revs), and a chirp or squeak at low speed. Ignore those and the joint can let go, risking damage to the shaft, underbody, or even a loss of drive.

Replacement options depend on what’s fitted. Toyota commonly supplies the complete propeller shaft as an assembly for this era, as the original U‑joints may be staked and not intended to be serviced individually. Many driveline specialists can rebuild the shaft with quality replacement joints and balance it, which can be cost‑effective. When refitting, ensure correct phasing of the yokes and torque the flange bolts to spec from the Toyota manual. After install, a quick road test for vibration at 60–100 km/h helps confirm all’s well.

For 2WD 1999 RAV4s without a rear prop shaft, universal joints aren’t present, attention should instead focus on the front CV joints and boots during routine servicing.

How can someone tell if their 1999 RAV4 actually has universal joints?

If it’s an AWD/4WD model, it has a rear propeller shaft running from the transfer case to the rear diff, with U‑joints at its ends. FWD models don’t have a rear shaft and therefore no U‑joints. A quick look underneath will show a long, tube‑shaped shaft down the centre heading to the rear axle if it’s AWD.

Are the RAV4’s universal joints greasable, and how often should they be serviced?

Factory U‑joints on many 1999 RAV4s are sealed and not greasable. There’s no set greasing interval, instead, have them inspected every 20,000–30,000 km (or sooner if used off‑road or on the beach). Aftermarket rebuilds may use greasable joints—follow the supplier’s advice if fitted.

What are the common signs the universal joints need replacing on a 1999 RAV4?

Common signs include a clunk when selecting drive or reverse, vibration that follows road speed, and chirping or squeaking at low speeds. Any play felt at the joint caps with the shaft disconnected is a red flag. If in doubt, get a driveline specialist to check it and balance the shaft after repair.
