Jason,

Just went thru the same issue with a big TR diff.=C2=A0 The major suppliers=
 provide slightly different bearings at about a $40 to $50 price point. The=
 original bearing is available for almost $500 !!!!
The numbers on the bearing are the same except for the suffix on the bearin=
g (15100 vs 15100SR in this case). Both will fit, but the differences inclu=
de thickness among other specs.
Check the numbers that you are using carefully.

Been called a bit off spec myself...
