What happens when a universal joint goes bad?
This is the ultimate failure mode for a universal joint – literally breaking, and allowing the drive shaft to drop to the pavement, no longer transferring power. Repair at this point will include much more than the universal joint, and may require full driveshaft replacement or more.
Can you drive a car without a universal joint?
Without a universal joint (or U-joint), you won’t be able to drive a vehicle. To make sure of the good health of your car and your safety on the road, you should be able to pick up the signs of bad universal joint.
Why do rear wheel drive cars use universal joints?
This allows each end of the driveshaft, and its associated universal joint, to bend with each rotation of the driveshaft in order to handle the misalignment (as a side note, rear-wheel drive cars now mostly utilize constant-velocity joints for the same purpose, which permit far smoother flexibility of drive shaft rotation).
What happens when a universal joint breaks in a truck?
You’ve probably seen it before: a truck on the side of the road, with the drive shaft lying under the vehicle, no longer attached to the transmission or rear axle. This is the ultimate failure mode for a universal joint – literally breaking, and allowing the drive shaft to drop to the pavement, no longer transferring power.
What are the symptoms of a bad universal joint?
1. Squeaking noise when starting to move (forward or reverse) 2. “Clunk” with a ringing sound when shifting from Drive to Reverse 3. Vibration felt throughout the vehicle while moving forward at speed 4. Transmission fluid leaks from the rear of the transmission 5. Vehicle cannot move under its own power; driveshaft dislocated
