 The 2002 Ford Explorer is junk! Even Ford will not stand behind it. Lets see: New Transmission ($3k), new front and back timing tensioners ($2700), new wheel bearings ($400 each), new wheel springs ($400 each), new window regulators ($380 each), new back window ($800), new 4X4 module ($500), new fuel pump ($750), front suspenion things, work on the electrical system several times ($$), new O2 sensor, etc, etc. It's paid for but the problems started around 80K miles. Ford really made a POS. I know I am forgetting some repairs, there were too many. Quality is NOT job #1 at Ford. Time to buy foreign.
