2000 Suzuki King Quad 300 left front wheel doesnt move but right does Please be an easy fix!?

[Karen McDowell]

Went to change oil and get my sons  2000 Suzuki King Quad 300 ready for spring and found the left front wheel wont move at all but the right does. Doesn't matter if it's 2 or 4 wheel drive same issue. Nothing looks bent, tie rod ends and ball joints in place jacked it up and shook wheel and bearing seems tight. Any ideas before I tear the dang thing apart?  Of course my son has no idea what happened.

Have you checked the brake caliper? Sometimes if you leave the brake locked while it sits the piston on the caliper gets stuck and wont retract.   
 

If its frozen then I would think its a brake thing if it moves a little and jams then i would look more to the differential.     
Jack the front up and see if you can rotate the drive shaft to that wheel. It should move a hair in each direction.  If so then at least you know its probably  not in the differential. 
It could be as simple as a frozen caliper. 

If not then take the fill cap off of the differential and see what the fluid looks like and see what the gears look like.

 

And welcome to Quadcrazy btw!
