I'd say the issue is the spool. Anytime the hubs are locked in (whether actually in 4x4 or not), both front tires will be fighting each other when trying to turn. So either loose the spool, or learn to live with it.

i agree its the spool.no doubt about it.im not gonna loose the spool as i only have real issues when we are in the tight curvy trails. it was a cheap option at the time when i put the spool in.i ordered it when i bought my tcase gears and was juggling funds around on other projects as well...i will try the mentioned above mod and see if it helps at all.chances are with low tire pressure and heavy tires it wont.i plan to sas it once my buddy decides what he is doin with his sami because he said i can have his front axle if he goes with sumthing different.after he seen how capable my old sami was and my tracker is i think he will just keep it stock axle wise....thanks for the comments
