I need some help with a Ford Ranger Edge with the 4.0 6 cyl. First I will tell you,I am not a truck mechanic.I have done the obligatory alternator,plugs, battery,brake pads and rotors, etc. I have been in the lawn business for ten years and can turn a wrench fine. I have to see if I can get this solved w/out going to a mechanic and paying the $1000 I was quoted for the job. Due to a parent I am caring for having a major medical problem recently,funds are very low. Any and all help is greatly appreciated. The problem: I recently had the lower ball joints replace and had new tires put on. I have a Sno Way plow for it and I do some residentials and two SMALL( about 5 parking spots each) commercials with it. Now I find that the upper ball joint on the drivers side may be rattling a bit. I do not have the money to replace it right now. No snow has meant no pay. Question: Can I jack the truck up and tighten it down somehow to make it last a little bit longer? If so, do I just tighten the to nuts on top and how far can I go without throwing off the alignment? I have gotten some great info from this site from a great bunch of guys, I hope you can enlighten me on this and maybe I will be able to return the favor someday. Happy New Year!!
