Why do I need to replace my drive shaft?

Your drive shaft may need to be replaced because of wear and tear, or because a modification to the suspension of your vehicle has occured. When a vehicle is lifted, the distance between the transfer case and your axles increases. With this increase in distance, attempting to use a stock drive shaft could result in the drive shaft separating while under flex, or the onset of a new driveline vibration. If you have a vibration issue, see the Double Cardan question below for answers.

How do I measure my drive shaft length?

Measurement is critically important. Too long and it could break your transfer case, too short and it could fall apart. Visit our page on how to measure your drive shaft for all the important details.

How do I determine which series U-Joint I need?

1310, 1350, 1410

Do I need a Double Cardan or Standard Style drive shaft?

Double cardan shafts utilize multiple u-joints with a center ball to solve the vibrations caused by an increase in drive line angle. Driveline vibration can occur for multiple reasons. When a vehicle is lifted the angles of the drive shafts become greater. Due to the way a drive shaft with u-joints work, the vibration comes from the u-joints trying to do their job. While this is a vibration you could live with, your transfer case won't be happy about it. Eventually the seals will go and, if you catch the leak in time, it can be fixed but, a transfer case that is run low on fluid, won't be a happy transfer case for long. In the end, it's less expensive to install the correct components rather than deal with the failed ones.

If you order a Double Cardan shaft, the yoke on the transfer case will need to be upgraded as well. The best and most cost effective way to do this is with a Slip Yoke Eliminator kit. Keep in mind, that this kit shortens the main shaft in the transfer case as a means for reducing driveline angle. You must perform your drive shaft measurement after installing the SYE kit!

Is it necessary to replace the drive shaft straps and bolts when installing a new drive shaft?

The correct answer is yes, you should. These are the tiny little components that hold your drive shaft in place and in many ways, take the abuse that torque, horsepower, and hoping deliver. If they are weak, the risk of your drive shaft coming loose under load increases. You do not want to have a drive shaft banging around under your vehicle at 2,000 RPM, it's an aweful noise and feeling to have. For just a few dollars, you can add piece of mind by replacing them.
