    Hi Andrew,

    Anytime you increase the angle of your drive shaft you decrease it's longevity.

    If you want the drive shaft to last you might consider having a custom shaft made with a CV joint added in on the top end. The ultimate cure is to increase your pinion angle so the pinion nose points upward at more of an angle.

    Everyone thats put on a 6" lift has had U-joint problems at one time or another.
    As Jimmiee posted having a new shaft built with a CV instead of the common U-joint would help.
    Also look at transfer case shims or transfercase drop kits (same thing).
    Spicer introduced a new double Cardan CV joint to the market a few months ago, I havent had a chance to use one yet but from the marketing literature and feedback from those that have used it I think it'll cure a lot of problems for lifted trucks.
    With a 6" lift you probably need a slightly longer D/S anyways, yours is probably riding on the end of the slip joint splines and one good stretch of the suspension will drop it out.
