i just completed my Trail tough YJ missing links up front, SPOA lift on my 93 samurai. when i have the truck up on the rack with the suspension hanging, both my driveshafts bind and cant be turned. anyone else have this problem? how did you solve it?
You need to clearance your yokes. You will most likely ned to disassemble your shafts to do this but use a die grinder with a carbide burr and remove some of the material that the ear of the opposite yoke fits. You can also remove some material from the ears aswell.
Bean ther done that shimmed the rear with 4deg shims so mt pinion pointed at the t-case(ie ) trail only rig so vibes were not my concern although I didnt have any to speak of . the front I rotated up just a hair well that is just enough to keep my drag link from hitting the springs. one thing to remember is that on the trail that realy wont come in to play all that much its not often the entire suspension is just hanging when one tire down usually the other is up.
are you shure it is the u joinst binding or is the front driveline hitting the tranny crossmember mine hit the crosmember till i put the 1 inch spacer on the t case then later i got a extended slip yoke (when i moved the front axle forward ) the yoke is larger in diameter than the stock one and i was warned about clearance issues but that was easily solved i put five 3/8 washers under the polly mounted long arm no vibes from doing this either
i'm sure its the ujoint binding, you can watch it hit when you try to rotate it. i still have about .5" clearance at the cross member. how did you all clearance your yokes? just grind it down until it clears?
