The ESC is loose and I thought that may be interfearing with the control arms so I taped it in place since it was sliding back and forth. Next I am going to diconnect both the rudder and wheel clevis and centering the servo and then reconnecting them but it feels like something is binding up. Any suggesstions would be appreciated!
The 1st thing I would do is have a close look at the wheel clevis. They are designed to break the pins on a hard landing. I could see the pin being cracked or broken. That would alter normal steering.

If you disconnect the clevis/rod on the nose gear, will it turn freely? And with the nose gear still disconnected, does the rudder work properly?

If the rudder works fine with the nose gear disconnected, you've eliminated the servo and its setup.

If the wheel won't turn even being disconnected from the servo, then there's something wrong with the wheel mounting system.

I already replaced it. Did not fix it.

If I remember correctly, isn't there a screw in the collar that keeps the axle from sliding up in the bracket. If the screw isn't pointing forward when in neutral position it might hit the bracket when you rotate the wheel.

I've noticed on my Apprentice that one of the control arms from the rudder/steering servo hits the ESC and or battery wires when stick is far to one side, that was causing my steering to not be able to go in one direction as far as it could the other way along with diminished rudder deflection in one direction. My ESC was glued in with the white stuff and since your's isn't this probably isn't your problem. Just though I'd point that out in case anyone else has a similar problem.

I also had the same problem. I used a ziptie and some tape to pull the wire out of the way. I also replaced both push rods for the wheel and rudder. It seems to be working but I will not know until I fly again. I also replace the nose wheel and gear. I already had the extra parts since I knew I would need them from the crashes I had when I started learning to fly. lol!!!!

I crashed the club Apprentice a few times!

I'm sure you know this but make sure your nose gear is back centered before you fly. You'll probably have to take her to a large parking lot and run her along the ground at low speed without taking off. You may have to re-trim and make sure you have restored full left and right steering.

I've also seen further back in the thread that people had trouble with their nose gear not lining up with the rudder, could make for a nasty landing...

I'd line up the rudder with the vertical stabilizer at zero trim by adjusting the "turnbuckle" at the servo and then "drive" the Apprentice and make adjustments to the nose gear's servo arm until it lines up (drives strait) with the rudder.

I'm sure you already know this but I'm posting in case noobs are reading this and have a need to replace one or both of the rudder/nose gear rods and think they can just estimate and drop one (them) in.

From my experience, begin with allowing the plane to completely power up and let the servos center. Then look to adjusting the clevices for the rudder and nose gear. You also want to move the nose gear clevis out one position on the servo arm. It will improve the turning radius immensely. If the rudder is mechanically aligned with the fin, you can almost eyeball the nose wheel alignment. All you really need to do is just push it along the floor or ground and you can tell if you need any additional clevis adjustment.
