I done this job a quite a few times on 18's and 17's and it is not too bad , you need to hope that the bearing didn't wollow out the end of the housing and ruin the axle as I have seen that too many times , the reason I seen this job so many times was they were using solid tires and tracks and the machine can't handle it , I have also seen where you should go ahead a do all 4 wheels as the other ones will be right behind and you don't want to wollow the housing , try and keep the string , rope , wire etc off the axle end as it seems to be a major factor in bearing failure as it gets into the seal and it don't take long from that point to see failure
