Try popping off the piece of trim underneath the window. The window motor is in there and if yours is like mine, there is a bundle of wires in there that is torn to shreds. You can jump that motor with a spare battery to verify the motor works.
I have been very happy with my set of Kumho AT51s. They are cheap, 10-ply, aggressive looking, and also snow-rated. I've never gotten stuck with them offroad or in the deep snow we get at the ski resorts here. No highway howl from them that I've noticed. I've only got 5k on mine so I can't...
Pull out the EFI in your circuit box for ~20 minutes to reset your computer. Though I think your problem is more likely a small undetected leak at your filter. I recently swapped my filter and I had to go at the threads with a wire brush to stop it from leaking.
If you encounter another 4runner with rear gate handle issues, you can often get it open by pushing the license plate in towards the front of the vehicle while you lift up. Spraying the latch mechanism with some Pb Blaster and slamming it a couple dozen times got me back to a fully functional...

Did the rear diff fluid and took off the running boards to prep for a trip to Moab this weekend. Was going to do the tcase fluid too but when I got under there I was met with a big empty hole where there should have been a fill plug....
Echoing not to worry about high mileage. If it's high mileage it's probably a lot of highway miles. Highway means less shifting and less wear. I'd take a 250k tranny over a 100k NYC tranny any day.
Picked up a front diff assembly from a rollover for $150. The swap took ~4 hours, most of the time was spent wiggling it out as it's wedged in pretty tight between the cross member and oil pan. Only special tool I needed was a 12mm hex. Now I'm back in action and no worse for wear!
