Hi all, I wonder if there is anybody who could give some advice please. We have an old Bobcat 643 we think about early eightys but not totally sure. We use it around the paddock so not worked to hard. For a bit it has been a little clunky on the front right wheel. Today it didnt feel right and I noticed the same wheel is not driving. I jacked the beast up and that front wheel spins freely. The right rear wheel appears to be driving ok. Could I please get some guidance on what to look at or if anybody knows an honest decent repairman around Brisbane Australia. Thank you very much for your time. Carl.
