Frequently Asked Questions

What are the key signs that my drivetrain needs replacement parts?

Common signs include unusual noises (clunking, grinding, humming, or whining) coming from under the vehicle, excessive vibration during acceleration, difficulty shifting gears, or fluid leaks around the transmission or differential housing.

What is the difference between a slip yoke and a U-joint?

The U-joint (Universal Joint) is a flexible coupling that allows the drive shaft to move up and down with the suspension. The slip yoke is the component that slides into the transmission or transfer case, allowing the drive shaft to change length as the suspension travels.

Why is using the correct transmission fluid important?

Modern transmissions rely on specific fluid viscosity and friction modifiers for precise operation. Using the wrong fluid can lead to overheating, poor clutch engagement, harsh shifting, and potential damage to solenoids and internal components.
