Use Dry Lube
Get your hands on a dry lubricant, and use it to keep things as free as possible in your vehicle’s drivetrain. Lubricants such as Trakpower’s Krytech use a wax or Teflon that’s suspended in a solution that carries it to whatever part you apply it to; that solution evaporates and leaves the dry lubricant behind. This allows it to get into areas that grease and other lubricants can’t get into, like the tight-fitting parts of a universal joint, for example. The other advantage that a dry lubricant has is that it won’t attract dirt and other debris. Use the dry lubricant on the spur gear, gears in the transmission housing, driveshafts, and bearings. You can also use it on other moving parts, such as the suspension arms, hubs, drive cups, and more.
The drivetrain will benefit from a coating of lubricant and make your vehicle faster.
