I have a 1993 ford f150 and lately i have been noticing a wobble in the front end. It is noticable at 50 mph or so, but is worse at slower speeds. I have jacked the front end up and tried to wiggle the tires but everything seems to be tight. Any ideas as to what might be causing the front end to shake? Also my passenger side manual locking hub is loose and rattles going down the road. how should i fix this?

 

That is a very heavy front suspention on those 4x4's. You need to jack up the front axle, close to the wheel and then put a strong prybar under the tire and lift up. It would help if you got someone else to do the lifting while you looked at the balljoint. Checking the tierod ends and the draglink would be a good thing also.
