1999 Ford Explorer 4 door 4wd, parts or fix

1999 Ford Explorer 4.0 engine, uto trans, wd. 208000 miles. It has been sitting for about 3 years. Previous owner parked it because of the rear pinion bearing being loose & noisy. It does run, ut not the best considering it has 3 yr. old gas in it. I did run it on a hoist and it does seem to shift ok and 4x4 works. I believe tie rods checked ok, t will probably need some brake work as rotors are rusty. Rear brakes look like they may have been replaced shortly before it was parked. All the tires go flat in less than a day, retty sure it's due to rim leaks. This is sold As-Is with absolutely no warranty. You are welcome to come check it out. Does not include temporary spares which are on it now. If it does not sell, will be parting it out, o watch for upcoming auctions. Please ask any questions.
