I own an 873C and as I was turning to the left I heard a thunk noise. I jacked up the rear and i measured 3/32 play on the right wheel and 5/32 on the left wheel. Prior to this noise i noticed the left and then the right axle seals leaking. Iguess that was a hint. The play in the axles is in and out not up or down. The local Bobcat dealer quoted me 2500 to replace the bearings and seals. I can't remember if it was for just the rear or all four. Does that sound right? Is this a job that a decent home mechanic can do? I also replaced the head gasket on this loader due to leakage 8 years ago, and it is still going strong. Do the 4 main pump flex hoses need to be removed? I have some access to the rear chain case cover. It should come off easily. I have the manual for it. It makes the job sound doable. Thank you, Rich M-37
