At that point a person might as well do bearing since you have to remove them. Front axles are not bad, rears are a bear since the hydrostatic is in the way. Either curse around it or pull it out. I quote 6 hours of labor per axle remove/ install job on newer machines where the back axle bolt and sprocket are much easier to get at. I'd probably charge more on a 40's. Moving on, 743B have the newer two piece axle. Much simpler because the axle doesn't come out. Remove the hub, replace the seal. I'd quote 2 hours per seal because sometimes the hubs can be fun to get off. To tell which hub you have for sure, look at it, does it have a big center bolt? That's a two piece. One piece, there is no bolt. Not knowing the dealers hourly rate, I can only guess they are quoting 12+ hours of labor. So my guess is that is the worse case price if it is a one piece.</p></blockquote><p></p>
