Power Steering tick/issue

So about a week ago, my truck would make a squealing sound whenever I would crank on the steering wheel. Then two days ago I noticed a loud ticking sound coming from the engine, I assumed it was related to my power steering because of the squealing sound that started the previous week. Also the ticking sound would go away as I cranked on the steering wheel (but come back after holding it cranked for a few seconds). Yesterday, I removed most of my power steering fluid and replaced it with Bar's power steering repair fluid. My friend had a problem with his power steering making a squealing sound, and said that the bar's totally fixed it. But the ticking sound was still there.

I couldn't exactly locate the sound, but I was thinking it was a loose belt. Whenever I turned on the truck, the sound would start withing 10 seconds of starting. So today I tightened the belt up. I went out to test drive it, and after about 6 miles the sound was just getting significantly worse and worse. I cranked up my music to drown the sound and headed home. Right before I pulled into my driveway I shut off my music and the sound was completely gone...

Anyone have a similar issue?
