[V8] Tbelt roller noise et al

[Mike Del Tergo]

Question, after hearing what seemed like LF wheel bearing noises, put the V8 
up and now seems to still have "bearing" noises but seem to be from under 
the TBelt cover.  Service was done ~1,000 miles ago with the instructions to 
replace all the rollers. Actually I think that is all they did 2 rollers PN 
077 109 243A + 244A. none of the other ajusters/tensioners.  Which is the 
most likely culprit as I remove the covers and check further, any 
catastrophic?
Also in checking for wheel bearing play heard sort of a "clicking" on tranny 
side of front 1/2 shaft when rotating the wheel.  Seemed to come from the 
tranny, any worrries there?
thx
