CV joint tips: The Spicer CJ joint provided with this Denny's driveshaft came with bolts but not lock washers. Bringhurst says that this is the way they come on OE trucks and that Loctite should be applied to all four bolts. The CV joint has an inverted grease fitting and should be lubed every 2,000 miles. We required a new output yoke at the rear of the transfer case to accept the CV joint. Ford used at least two different output yokes on the rear of the Model 20, so you'll need to measure yours if you need to replace it. Denny's stocks all popular output and pinion yokes.
