I bought a denton rebuildable for my sons ltr, 3 weeks later it was blown. I called denton direct and he told me no problem send it back and he would rebuild it " for about 55 dollars plus shipping". He also said we might have got some dirt on the shaft and it blew out the seal, Its on a quad of coarse we got dirt on the shaft. Thats a third of what i have in it. Im not gonna pay 55 dollars every 3 weeks. Has anyone else had this problem with there Dentons. HELP
