I was wondering how the caster should be set on the rear axle when doing 4WS? Should I try to get it at zero or should I clock the chubs to give a little castor? I am using stock chubs and knuckles

I run zero in the rear.

Hey guys just finished my wraith tonight and I also added the 4WS and don't know exactly what you guys mean by zero caster on the rear axle, or is that for both axles. Can you guy please school me on this cause I'm lost. Harley thanks for the wiring diagram for the 4PL 4WS and the winch it worked just fine.

Zero Caster means the c hubs will be straight up and down, as opposed to the front having a positive (I think, can't recall how it works) caster with the top of the c hub leaning back towards the center of the rig and the bottom tipped towards the front. I have been wondering how the rear caster will effect performance, I plan to mess around with it on my rig. Right now it is at zero and its working nicely but want to try out some positive and negative to see if there is a sweet spot.

If you don't mind could you please post a close up pick of what you got. I have my C-Hubs straight up and down. Would that mean that the pumpkin should be at a 90 degree angle or different. Thanks

With you wraith sitting on a flat surface, you want the chubs straight up and down. The splines on the chubs are pretty coarse so moving it one spline moves it alot. On mine I could not get it perfect but it is close. If I move it one spline either way it gives me positive or negative caster. Sweet looking wraith!

Thanks Psycho-Savvy, followed your instruction and got zero caster now for the rear 4WS.
