Hi,
I've searched through and through on the forums how to measure, and how to interpret the measurements you get for a Rear Driveshaft with a SYE.
To be exact on my setup, I've got a 98TJ, but it's quite the frankenstein. It is a 98' with a 2006 Frame and a 2004 body. I've got a 4" lift I just installed a Teraflex SYE Extreme short shaft kit and my rear axle is a Ford 8.8. I do have a double cardan rear driveshaft for it, but I find it being a little short. Fully closed from center of the U-joint to the mounting flange, for the ford 8.8, it measures 17".
When I bolt the driveshaft in place, I've got about 4.5" of the splines showing and that means I've only got 1.25" of spline still inside the slip yoke. I'm scared that I'll pull the driveshaft apart when wheeling around with that. I've tried to measure between the flange of the diff to the yoke on the SYE, but how do I know what length my driveshaft should be fully collapsed. I'd like to know how much longer I should make my driveshaft, so I can bring it to a shop and get it lengthened.
This is just me thinking, but I Think at least 1.5" longer should be minimum. So that at Ride height, I'd at least have about 3" of the spline still in the slip yoke to drive and it should have enough length to not pop out when wheeling.
I'll read all of your answers and hoping some people with some expertise could have an answer to my question. Thanks!
