When you say it binds up and clicks, do you mean at full right or left of the turning travel? If this is the case, you probably need to set the steering end points. There are 2 round knobs on your radio (transmitter), one is identified as D/R and the other should be something like ST/TR or ST/Trim. Start with the ST/TR. This is how you set the steering to track the RC in a straight line. Without using the steering wheel, throttle the RC forward. If it goes slightly right, turn the ST/TR knob slightly to the left. Do the opposite if the RC goes to the left. It takes some time to get the RC to track in a perfectly straight line and sometimes you just can't get it perfectly straight so get it tracking as best you can.
Once you have it tracking straight it is time to set the D/R (Dual/Rate). This controls how far the servo can travel to turn the front wheels. Just so you can see how this works, set the D/R knob to Zero. Turn the transmitter steering wheel. The wheels should not turn or if they do, only very little. With the RC upside down and the D/R knob at Zero, turn the transmitter steering wheel full right, hold it there, and start turning the D/R knob and you should see the wheels start to turn. Watch the wheels, when they stop turning that is the "endpoint". Make a note of where the pointer on the adjustment knob is and turn it back to Zero. Generally, the wheels will stop turning before the D/R knob gets to the end of its rotation. Now do the same thing turning left. Again, make a note of where the pointer is on the adjustment knob when the wheels stop turning left. You will probably find the pointer moves farther when turning in one direction than in the other. Transmitters with this type of D/R adjustment can't adjust left and right endpoints individually. So, turn the D/R knob to the lesser of the 2 points of the right and left travel. You have now set the steering endpoint.
If the wheels are physically stopped from turning any further but the D/R is set too high, the servo will be stalled but will continue to try to move. This puts more stress on the gears and can generate heat in the servo electronic control board. In this situation, you risk stripping servo gears and/or frying the servo electronics.
Every time you change a servo you need to go through this procedure. And, if for some reason you have to make a significant change to the ST/TR you should also do a D/R adjustment.
Let us know if this corrects the binding and clicking.
