Mitch and Larry,
Yes some of the repop bearings have the spiral grease groove while other repops do not. So you cannot rely just on the grooves being there. The bearings that failed on two of our club member cars did have the grooves even though they were worn down. Both members found the problems while doing their greasing maintenance. Also, both owners had been using the Sta-Lube grease.
