Loud grinding / screeching noise

[wolf_fav]

Hello all ,
I finally got all my leaks situated on my injector pump . I got in her today and started to mess around when all of a sudden I started to hear a loud grinding , screeching sort of noise coming from the left side of the machine . I almost feel like I could feel it in the T handle but didn't want to run it like that for too long . Where do I start ? Where should I look ?
Any suggestions are deeply appreciated

Got machine up in air and figured out that at the very least the rear wheel bearing is blown out . The service manual isn't very clear on the procedure to do the axel bearings . Any tips or trick any one can relay to me would be much appreciated.
