That's a good score, paid 1500$ for my 99 Explorer XLT which was great, it runs, did an oil change, new filter, new air filter, changed some bulbs, fixed front fog light and replaced a relay under the air intake to get front washer pump to spray. Basically it works, has 278,000km on it, the roads out here are riddled with potholes and as much as I would like to think it is the roads, it probably isn't, it dives when I suddenly brake, and feels a bit bouncy when roads get a little rough, (built up ice, potholes, etc) there is a definite metal almost grinding noise, faint but still there, found out theres a leak in the rear differential and topped it up with the appropriate oil... Just for got to put the friction modifier in.. Was hoping to keep it greased until I have time to change the gasket. But there's still some sort of humm as you accelerate in it. I was told by a mechanic that the front left wheel has some play to it and that the hub and bearing assembly needs to be replaced, said it wasn't bad but wanted 800$ for the job... I basically ####ed on out of there. Thinking I might be able to do it for less... I'm also drawing the 171+174 error code combo, my guess is a dead sensor or a vacuum leak... Anybody got any thoughts on some of these issues? Even to lead me in the right direction?? Thanks for reading!! I want to get this bad boy driving a bit softer as there have been times where doing 60km/h and hit a pothole and I believe had "wheel hop" which caused my ass end to end up in the lane next to me...
