I've just bought my mates bullet St flux for £50, he only used it twice and broke it second outing breaking the front steering knuckle. He had it fixed for me buying it but there was a few washers and things missing that I have replaced. I've noticed a lot of movement in the front dog bone so stripped it down and noticed that the drive cups all have rubber washer in the but I'm 1 missing at the front, it doesn't mention the washer in the manual unless it's part of the cup, would anyone have a part number for the washer?
