FAQ
Q1: Is it normal for the Universal Drive Shaft to have slight surface scratches?
Yes. Light scratches from rocks or gravel are normal and usually do not affect performance.
Q2: Can I continue driving if the drive shaft is slightly bent?
It is not recommended. A bent drive shaft may cause vibration, increase wear on other drivetrain components, and eventually fail completely.
Q3: Why is my drivetrain making clicking or knocking noises?
This may indicate wear, looseness, or damage in the drive shaft or its joints and should be inspected promptly.
Q4: Does hard bashing shorten the service life of the drive shaft?
Yes. Frequent high-impact driving increases drivetrain loads and can accelerate wear or cause damage.
Q5: How often should I inspect the Universal Drive Shaft?
It is recommended to inspect it after every hard off-road session or significant impact to ensure it remains in good condition.
