What would or could cause clicking in right front wheel when in 4 wheel drive and turning right
SOURCE: clicking noise from font driver side wheel 4 wheel drive
There is a vacum powered actuator on the front differential housing on the passenger side. It pushes one way for 2WD and the other way for 4WD. If it gets an erratic vacum signal it can cause the clicking as it goes between 2WD and 4WD. It gets it's vacum from two valves mounted on the firewall just behind the battery(to left). The white line feeds manifold vacum to the valves. Check for vacum at white line with engine running. If no vacum there is a break in line from manifold (not likely in this case). If vacum check the pink and blue lines by applying vacum to each one. The vacum should hold. If not check lines from valves to vacum actuator. If both lines hold vacum check valves. Remove electrical connectors from both valves. Connect a wire from one of the terminals of the valve to ground. Touch a wire from the battery + to the other terminal of the valve. Listen for a clicking sound. If no sound valve is bad. Replace valves(s). Also have someone watch position of actuator shaft as you move the selector between 2WD and 4WD. There should be movement. If there is an intermittent problem sometimes it will and other times it won't.

Two things maybe your problem:1 .Front axle actuator to engage 4wd is not releasing. 2. Front axle u-joint needs replacing. Lift car on jacks with front end off ground. Then spin tires by hand as fast as you can and see if you hear the noise and where it is coming from ( spin in both directions).
Testimonial: "Thank you! It was the actuator that was causing the problem."

Most likely U Joints in the front axles. These will only turn in 4 wheel drive.
