04 R6 Front Wheel Squeaking!

My buddy has a 04 R6 and he just got it it has like 7500 miles on it. It makes noise only after warming up for like a few mins of riding. The breaks are not depressed while it squeakes which leads me to the wheel itself. I am thinkin its the wheel bearings. It is still smooth operation it spins freely without any jerkyness we put it on a stand and all but squeaks. I am thinking it needs repacked. I have never done this and was told that some bearings are prepacked and sealed. What is the proper way to repack the front wheel bearings on an 2004 R6. IF anyone could help i would appreciate it. Pictures are always a plus.
