RE cut the shaft Slip Yoke Eliminator...

[Ryan Schmaltz]

heres the thing with this 1, they build the thing so that u have to buy the drive shaft from them. I figured out how to get around this costly purchase. i was out in the garage tinkering around on the ford 9" I am swapping in and i noticed something. the bolt pattern for SYE and the 9" pinon yoke are exactly the same. I thought sweet I can make my own drive shaft. Not so, in order for this to work a person would have to make 3/4" -7/8" shim. I dont like the idea of that so I started thinking. i popped the snap ring that holds the washer in out of the SYE. The side of the SYE the gose to the t-case isnt splined for 5/8" or so. I took SYE and put it on the output shaft backwardsand slid it on so the splines of the SYE were about a 1/16" past the start of the output shaft. I then cut the non-splined part of the SYE about 1/8" long and then ground the rest off square and flush with the outputshaft. After that i took the washer and centered it over the centering hole from when the output shaftwas made, tacked and then welded the washer on. Done deal. Not quite. there is still just over 1/4" gap inbetween the 2 mating surface's. O.K. I thought i then took the 9" yoke and die grinded about 3/32 deep were the center of the SYE goes. I then made a 1/4" shim. this easy mod. only took 45 min or an hour. it works good for me cuz it will use the same ujoint front and rear for the rear driveshaft. not so convinient for those of u running stock diffs or other diffs.but it will still work if u have some basic fab. skills and a lil common sence.
