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.
I have a 2002 Ford Explorer Limited. It has over 150k miles on it, and I haven't had a single problem. I think you just have bad luck. I purchased mine new in 2002. If you bought yours used, maybe the previous owner didn't treat it as nicely as you had hoped?
I am about to purchase a 2002 Explorer XLS, from a customer, that I have serviced for 6 years. They have their share of problems and I have the invoices to prove that, but they are not as bad as people claim. I replaced most of the items you mentioned, but not for near the cost you paid. $500 for a 4X4 module? I replaced my customer's for a total cost of about $275. This has a 118K and runs excellent. I did the window regulators for under $300.00 each.
It seems that that not only did you have multiple problems, but to add insult to injury, the repair costs were too high.
WOW can i be your Mechanic I will take good care of you and be Rich!! Fuel Pump $177 parts and labor.. Wheel bearings $85 Each installed. Rebuilt transmission . $1300 with 24 month warranty, Back window? Why? If you smashed it you can get replace at salvage yard $100-125 plus $125 labor. Window regulators $270 installed.new!
I had 3 explorers and 4 expeditions and Have only had 1 time an Ac issue that was warranty work because ford did stand behind the factory warranty.
Sounds like you needed to trade and use common sense before you spent over $9000 as you claim,sorry not insult but makes no sense...
