hi? I need serious help. I dont know what going on with my boat trailer axel. i have a 95 escort trailer for boat. It doesn't have brakes and it a single wheel trailer. My bearing completely damage and mashed when i removed it. i bought new hub and new bearing and everything new except axel. my problem is d bearing will start to go in or glide in and stop. I tried the bearing on d other side of the trailer same thing like the new bearing. Start going in and stop. what could be my problem. before puting d new bearing i cleaned the axel with a scotch cloth to clean and smooth. am having this problem on the left side.
