How often should I grease my shaft and what type of grease should I use?

Any Tom Wood's drive shaft is fully greased before we ship it out. So initially, all you need to do is install it. Down the road however you will need to grease your drive shaft to ensure a long life. A good guideline to start with is to grease your shaft every oil change. If you go wheeling and drive through a lot of dirt or water, grease your shaft as soon as you get home. This will flush out the contaminants before they have a chance to do much harm. We recommend a good quality grease with calcium sulfonate as an additive, but any grease will do. Grade 2 is the best for rotating parts like joints and CV center balls, and is the best all around. Grade 1 is good for things like slip yokes, where a lighter grease will help to avoid excessive pressure build up when your drive shaft compresses. 

Just don't overlook that cv center ball! Take a look at the center ball anatomy pictures below. For our complete guide to greasing your drive shaft, click here.
