Driveshaft Angle Explained This video will demonstrate the proper angles for a drive shaft in a stock Jeep or Truck and how the rules change when you add a suspension lift.    The video below demonstrates what is happening to the shaft at different angles, how improper angles can cause speed oscillations, and it focuses more on 2WD vehicles and applications that are not lifted Jeeps and trucks. Plus it's just down right fun to watch. As the title screen suggests, in many ways it is a better driveshaft video!    The article below offers an in depth explanation of...

Please bear with me! I'm really going somewhere here but there are a few precepts that we have to understand. Vibrations can be and often are the sum of different sources. Try to imagine this if you will... If you were to graph out a vibration, it will have an amplitude (strength) and a wave length (frequency). There are numerous sources of vibrations in anything mechanical. Everything in the world (probably the universe) has a natural frequency at which it will resonate. Exactly like the tuning fork your music teacher may have used. Your engine is really pulse driven, each...

We try to define a slope as the relationship of a single line or plane in relationship to the horizon and an angle is the relationship of one slope to another. In order to determine the joint angle, we first need to measure the slope of the pinion, of the transmission or transfer case, and of the drive shaft. The differences are the net joint angles. For example, if your drive shaft is 20 degrees and your transfer case is 5 degrees down, your joint angle is 15 degrees. If your drive shaft is 20 and your transfer case is...
