Truck had been making a clanking sound for some time. Got to a good mechanic over the "furlough" weekend and he went through it and said it sounds like ball joints in the front end. Ford made these without any way of greasing them up, no grease zerks. I remember reading something way back about getting a needle type of grease gun and just shooting grease in there. I know I'll have to replace them eventually, but notice I used the word "furlough," money getting a little tight now. Is this one of those things where the front end is just going to collapse, or do I have some time if I can't figure a way to get some grease in there?
