What are the symptoms of a damaged Crown driveshaft?
2 Answers
The symptoms of a damaged Crown driveshaft are: 1. The rotation of gears on the shaft may occasionally experience momentary pauses; 2. The pulley on the shaft exhibits wobbling during rotation; 3. The rotating gears on the shaft produce periodic meshing noise during operation; 4. The diameter of the shaft at the rolling bearing mating surface becomes reduced. The Crown is a mid-to-large-sized sedan under FAW Toyota, with body dimensions of 5020mm in length, 1805mm in width, and 1480mm in height, featuring a wheelbase of 2925mm. In terms of powertrain, the Crown is equipped with two engine options: a 2.5-liter naturally aspirated V6 engine and a 2.0-liter turbocharged engine.
Having driven for over a decade, the most obvious symptom of a Crown's driveshaft issue is severe body vibration, especially when exceeding 60 km/h—the steering wheel and seats shake like massage chairs. During acceleration or sudden speed increases, there's a distinct clunking noise from the chassis, which gets louder when turning. The scariest part is the jerking motion when coasting off throttle, making it feel like the rear wheels might give out at any moment. This is mostly caused by worn universal joints throwing the driveshaft out of balance, requiring immediate repair. Otherwise, a sudden lock-up at high speeds could be dangerous. Last time my friend's Crown had this, the mechanic warned that any delay could mean replacing the entire rear axle.
