how to replaced a window motor in a truck I got it out but I can not get brackets back in place

what can I do to solve problem,small tube in back of A/C unit seems to leak some but not useing the A/C unit?

I took my truck to my mechanic yesterday to have the rear wheel bearings replaced & he discovered that the differential gears had some chipped teeth on the gears and metal shavings in the gear oil pan cover. He said that, I need to have the rear end rebuilt. My truck has 174,535mi. I'm wondering how costly this repair will be & if I should have my mechanic do the repair or if another shop can be recommended

4 wheel drive
5.3 V8 engine
66000 miles

But it is throwing the p0443 code and sometimes the MAF sensor code. It just started randomly while driving down the road 2 days ago.

It will crank over and start. Sometimes for a second sometimes for 30 seconds. After reading it sounds like the system is not building enough pressure. I do not have the smoke system to perform that test. But it is throwing the p0443 code and sometimes the MAF sensor code. It just started randomly while driving down the road 2 days ago.

I have 2 of 5 OBDII monitors not reporting and have red exclamation marks on screen. They are catalyst and egr. I recorded data points and have the following excel doc attached.

I need help determining where to start with diagnosis. There are no engine codes. The maf and iat seem out of wack. See 20 data points and description below:

Truck was running fine and I see water temp gauge bouncing, but I new motor was not hot. And then I stopped at a red light and then turned green I pushed on gas pedal and engine hesitated, I let off pedal and is ok, but when I push pedal again I noticed water temp gauge bouncing more when I push pedal.I was wondering if sending unit could be shorted out and causing engine to hesitate when I push on gas pedal
