Torque steering problem

[Frenchy]

So I have a 1993 SE Sport. Still running the IFS. Already replaced my steering linkage(it was worn out) along with new ball joints. I also replaced the left CV Axle(inner boot torn). Along with all this I did lift it a little with Sway-A-Way torsions and Old Man EMU shocks and rear coils. Before all this was dont the Pathfinder was doing just fine. After all this I get torque steer when in 4WD and im on the throttle. To explain the torque steer I cant keep the steering center when on the throttle. It will go either left or right and not want to stay center. Before this it had no problem staying center. Anyone have an idea as to why?

Did you align the front end after doing all that steering/suspension work? Could be your toe is way off.

[Frenchy]

An alignment was done, but that doesnt mean it was done right. I plan to take it in again

[Slartibartfast]

Yeah, that's all I can think of that wouldn't make it favor one side consistently. Does it drive normally in 2WD?

[Frenchy]

In 2WD it does just fine. Omly in 4WD it has the issue.

Mine did this and it was too much toe in. Have the alignment re checked, it would be amplified x100 in 4wd.

I remembered today that the only time I've had the steering fight me in a 4x4 was when I shredded the spider gears in the front end of our IH snow plow. What was left of them kept trying to lock up, which made turning very difficult, though I suspect that was more aggressive centering than torque steer. 

 

Jack up the front, in 4x, hubs locked, and turn one wheel. See if it all turns smoothly. Then check over all the front suspension. Strut rods and UCA spindles especially. If a damaged strut rod chose this moment to let go, or a spindle bolt pulled its threads because it was too short after the lift (too many shims behind it), or something along those lines, the wheel could be dragging the damaged suspension around when you put power down. If this is the case, I'd expect it to be spooky under brakes, too. 
 

Edit: if you've got a tape measure and a couple pieces of something straight (I use angle iron), you can get a ballpark toe reading at home. Sounds like that's the first thing to check.
