    I odnt know why your d/s would be short the houseings are the same length from the houseing to the end of the pinion, did you swap in longer springs??

    no lift? and a 14bolt and the shaft is too short?? thats very odd. a 14bolt is actually longer making a truck with stock springs/no lift would need a SHORTER shaft...not longer

    no lift,either.very odd,indeed.i really need my truck.can't have it down for long.my theory(end of d/s to pinion is about 4 finger wide gap)smaller tires/rims might close the gap.this is my first project of this type.it would really comfort me to know it is'nt screwed up.

    does the shaft fall out of the tcase when you try to bolt it on? how much on the slip yoke is showing?

    Have no clue what the prob could be. The 14b swap is a direct bolt in, same d-shaft. Tires and wheels won't make any difference at all.


    I just re-read your post..Are you using the driveshaft that came from the donor truck?? If so, that's your problem. Use the shaft from your truck. Might have to use a 1350 u-joint /forums/images/graemlins/waytogo.gif

    Re: more axel swap woes...?\'s D/S related

    heres my theory: you have the shaft all the way slid into the Tcase (np208 right?) and dont realize that it is a slip yoke, meaning you can slide it in and out of the Tcase. try sliding it out enough to reach the pinion on the 14B and you should be good2go...but if it slips completely out of the Tcase B4 it reaches the rear end then you have a short shaft problem /forums/images/graemlins/rotfl.gif /forums/images/graemlins/histerical.gif (good term huh /forums/images/graemlins/whistling.gif) and you should be using yer stock driveline with a napa 447 u-joint

    no more axel swap woes!

    i'm now 3/4t.!!!it only took a week,three hours per morning before work.everything worked out after all.the d/s wasn't too short after all.i forgot that ipushed it all the way in to the case to get it out of the way /forums/images/graemlins/doah.gif.funny thing,though.i didn't need a conversion joint.the caps are the same size from 1/2t. d/s to 14ff pinion. /forums/images/graemlins/dunno.gifit was a major PITA for a beginner,but also a great learning experience and well worth the work involved.my 700r4 likes it much better than it did the 3:08's.the gov-lock works awesome,too.i'm finally seeing the full potential of that new 350ci.though my speedo reads 85mph when i'm doing approx.45mph.(but that's another post)any way,thanks for the inspiration. /forums/images/graemlins/thumb.gif
