I have a 2004 Landpride ZR52. Been a Helluva machine but there is some wear and tear. I need to replace Bearings on the axle shafts as the wheels are tilting in at the top. All I can find on the parts Diagram is a Land Pride Part number and they call it a Hydraulic Transmission but dont give me a number or name. Also they show the thing all blown out except for the axle and bearings. Does anyone know what it may be or where I can find out what it is> Do these transmissions have part numbers or model numbers on them?
