I have an 1988 Samurai spring over and a yf spring conversion with missing link. I bought it this way.  The previous owner placed wedges between the front axle and springs witch causes the front drive shaft be at an extreme angle.  If they were not their the drive shaft should have alot less angle thus not bind up when the front flexes. My question is why did he need to put the wedges their to begin with.  Thanks for the help.

Well in theory those wegdes should kinds "straighten" out your front drive shaft by turning the pinion towards the t-case BUT that does not work so well on the front because of a little thing called "cast/camber" or death wobble!!

Yes I understand about the death wobble.  It had a severe death wobble when I got it. I solved the wobble with a steering stabilizer.  These 1/2" wedges angle the front pinion down away from the t case witch produces a severe angle at the u-joints. would removing the wedges cause any unforseen problems other than straightening the drive shaft .

OK, You know about death wobble but do you know what causes it? Being a knuckle axle the trunion pins are how the tire pivots to turn. Your particular issue was caused by the SPOA perches being welded on at the wrong angle. On flat level ground place an angle finder on the flat part on the bottom of the front third member. You need to see 12 degrees. If you description is correct I suspect you have less than 12. There is a sweet spot on the bottom of the front tires where they pivot. To far one way or the other the tire slaps back and forth. You can cure this problem best by cutting and rotating the balls on the ends of the axle. It is not that tough to do but is the best of all worlds. You get to really lift the pinion flange up and have excellent driving manners.

Your comment that you fixed your death wobble with a stabilizer isn't the whole story, you have masked the real issue of wrong pinion angle. There is a slight (very slight) up angle on the front pinion flange not much but  not flat or down as you described.
