Driving with a Damaged U Joint
If you know that your vehicle has a damaged u joint then driving without replacing it is just asking for trouble.
Should you Chance a Bad U Joint?
The u joints are connection points along the drive line and if they are damaged or worn then they have the potential to disconnect the sections of the drive shaft. If this happens then the extent of the repair and the costs involved could be significant since complicated components like the transmission or the differential could be damaged. The best advice is not to drive with a clearly damaged u joint since there is a possibility of costly, vehicle-disabling complications.
If the symptoms are mild then driving with a bad u joint is possible, but for how long is uncertain. So, it is definitely better not to drive with a bad u joint and they should be checked as soon as possible if symptoms of a bad u joint are noticed.
