M8...
I have been having rear diff issues... to race meetings later and it both meets i have had diff problems... first it seem to eat the diff crown gear... very strange and second meet the bearing on the pinion went bang.. but this after the replacing the bearings and the diff against the pinion is not smooth...
Diff is smooth... pinion is fine... any ideas...
have shimmmed the diff... but to no affect... very annoying..
