Think this cold weather is making my jeep fall apart. So I have a little noise in the front end and the jeep is wondering a little. I know my unit bearings are worn out. I jacked it up and there is a little play in em but not real sloppy or anything. My question is: How long will it last before im stranded on the side of the road? I do plan on replacing them kinda soon, but I dont want it to fall apart in the meantime. I can handle the noise and everything, just dont want to be stranded.
