OK sure, lets see if I can help you out here. Do you know what a radius arm is? This is a link that connects the frame to the front axle.
On the end that connects to the frame, is a large round rubber bushing. While this one is not causing your problem, inspecting these periodically is not a bad idea.
Next is the bushing that is between the radius arm and the axle itself. These are called "C" bushings, because of their shape.
Next inspect the coil spring itself, and make sure that it is not bent, or does not look like the other side. If it is leaning, it may have become weak, and both may need replacement.
Carefull inspections of everything might provide you with the solution to your problem.
Perhaps if you take some pics of your ride, I can help you with your inspection. Nice resolution pics of the suspension components would be best.
You can e-mail me if you wish.
