center support bearing

Hey guys newbie here, 02 dbl cab trd 4x4 and I have already had to replace the center support bearing after running 2 1/2 spacers in the front and a 2 inch aal in the rear. Now its making the noise again, not all the time but just enough to be annoying! At least I think thats what is making the noise anyother ideas, or has anybody else had to deal with the same problem? Is there an easy way to lower the center support bearing so it will stop whinning?!

p.s. is there anybody else in NC who can tell me why we don't have a chapter!?
