What are the symptoms of a loose universal joint in a Corolla?

The symptoms of a loose universal joint in a Corolla are: 1. Abnormal noises and oil leakage; 2. Steering wheel wobbling or deviation. The function of a universal joint is to transmit power between two shafts with constantly changing relative positions and angles. Its types include: 1. Non-constant velocity universal joint; 2. Quasi-constant velocity universal joint; 3. Constant velocity universal joint; 4. Flexible universal joint. Taking the 2021 Pioneer Edition Corolla as an example, its body dimensions are: length 4635mm, width 1780mm, height 1455mm, with a wheelbase of 2700mm. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 116ps, a maximum power of 85kw, and a maximum torque of 185nm, paired with a 10-speed continuously variable transmission.
My Corolla has been running for almost ten years, and I've experienced issues with loose universal joints, with quite noticeable symptoms. First, when accelerating, I could hear a metallic clunking sound from under the car, especially loud when turning, as if something was grinding. Second, the steering wheel vibrated severely, particularly at high speeds, making it hard to hold steady. Once on a long trip, the car shook as if driving on a rough road—later I learned it was due to the universal joint causing instability in the drivetrain. The vibrations could also lead to uneven tire wear or worsening chassis noises. I always remind myself to regularly check and tighten the bolts, as small issues left unfixed can escalate to costly and unsafe driveshaft damage. During car washes, I inspect the undercarriage for oil stains, which are also signs of looseness—early intervention saves money and hassle.
