Noisy Idlers, ABS sensor woes, and Washer fluid leaks

Earlier last year I noticed wiper washer fluid was leaking all under the Jeep. The typical fix for this is replacing the washer fluid pump strainer which I did. Unfortunately this didn't really fix the problem so I decided to complete just replace the whole washer fluid bottle since the pump itself wasn't leaking. This is someone annoying to replace since it comes with a full tray assembly for where the ECU sits so I had SJF take on this project. Turns out the existing bottle itself was fine and my main issue was with the hose but whatever, I already had the new part so why not put it in anyway.

Since the Jeep was going to be with SJF for a while anyway, I figured i'd address a few other things like replacing the 4 ABS sensors since I would get the traction control light go on when driving on the highway for extended periods of time. This is typically caused by a bad sensor so got some new OEM ones to replace them. Turns out the rear rear abs wire had gotten damaged at some point and that was the main source of it but glad to have these sensors replaced anyway. I also had the crank sensor replaced which a very typical item to go bad on these vehicles. It's 10 years old now and I don't want to get stranded somewhere because of a bad sensor so a new OEM one went in as well.

New hub assembly
While the ABS sensors were getting replaced, the right front hub was showing some play so that got replaced. There were also some wear issues on one of the brake caliper bracket so had both front brake calipers and brackets completely replaced as they were pretty cheap anyway.

The front bumper stops were also completely worn out and falling apart so those were both replaced with fresh new ones. I had this whining supercharger like noise too from the engine when it was cold. At least one of the idler pulleys was not happy at all so I got them all replaced along with the tensioner and the main drive belt and now it's back to being silent.
