Have you ever been driving down the road wondering if you have birds chirping underneath your vehicle? Well I'm sure it has happened to the best of us. This is where driveline maintenance becomes very important.

Having a well maintained driveline will not only save you money, but will save you time and headache on the trail and even just normal road driving. A dry driveline starts by heating up to the point of making chirping noises then moves to grinding noises then soon after that you'll be lucky to keep your driveline from falling off and destroying the bottom of your vehicle. The driveline is key to the functionality of your vehicle, so come on guys and gals let's keep them up to par.

For a while there I thought that all I had to do was make sure there was grease in the u joints and the splines of the shaft itself, but I was wrong. In a CV style drive shaft which is very common in lifted vehicles there is a center link called the CV ball, which is about an inch in diameter. This ball is what allows the driveline to handle extreme angles at higher speeds without burning up. The trick is keeping this so called steel CV ball nice and greased at all times. This will require a needle zirk fitting and usually requires taking off the driveline, at least one end of it.

A big question is, How often should I grease the drivelines in my vehicle? Well my opinion is every 3000 miles, but it may differ with certain applications or driving styles. Every time I go out wheeling or on a long road trip I will usually get under there and re-grease it all, a properly grease driveline is a happy driveline.
