I replaced my '17 Z800 trail wheel bearings last year.
3 were shot at 10,000Km
Fronts were 30499-03080, rear 30499-03081
That's rear DAC3063W, front DAC 3055W
I don't know about that 9GQ number
ps I found that the right front spindle nut was quite loose although the cotter pin was in place and intact. Could not have 'come loose', must have been loose from the factory. Somebody needs a slap.
