So my 95' Ford Explorer was making a rattling sound and the front end felt "wobbly" like the tires were really under inflated. I took it to a general auto mechanic instead of Ford like I usually do to save $$$. The exhaust hanger broke and the muffler was rattling around, problem fixed and cheap! It has about 120K on it and is driven less than 10 mi. per day. After getting it back from the shop, the front end still felt strange like the front wheels were going to come off. I assumed the mechanic had it on a lift and would have found any obvious problem with the front end and not knowing much about auto mechanics... I went to check/fill up the tires. Total coincidence, when doing a sharp U-turn in the parking lot I realized I couldn't crank the wheel all the way left and the car started jumping. A quick inspection made it obvious what the problem is: I don't understand how that bolt with nuts attached on both ends would be able to rotate 90 degrees out of it's hole when their is no apparent damage or enlargement of the hole where it attaches. The bolt on the other side is completely gone. It seems someone must have removed the nut and put it back on? Driver's Side: What does this bar do and how dangerous was it driving with it like this? Thanks!
