Ok I picked up a 98 yamaha blaster. I put +5 stud wheel spacers a new chain and was missinga chain tightener bolt so I got that. Then all of a sudden my axle bearing went on the left near the sprocket after two or three weeks. I changed it out then a week later the same side bearing went out again. So I. Filled the carrier tube with grease and gear oil mixed and packed another set bearings. Then just this last weekend the same side is making noise agian. what's wrong I mean I only ride maybe one day a week and don't jump or do wheelies. I only realy power slide and do donuts. Does anyone know why its doing this I mean now I'm on the 4th set of bearing with in two months. The bearings I'm using is from all balls racing
