Need to either replace both spindles on my trailer or the entire axle. Have a buddy who is a good welder and says he can replace the spindles, but I'm concerned about getting them good and square to avoid tire issues in the future. How difficult of a job is it to ensure the new spindles are welded on correctly? Would I be better off just replacing the whole axle? It's just a standard square frame 2,000# axle with standard spindles welded on. The grease seal surface on the drivers side has been causing me issues for awhile now. Lets water into the hub. I've cleaned it up the best I could in the past, but when doing my yearly bearing maintenance last night the rear bearing was in pretty bad shape. And now the passenger side, which has never given me trouble, was in maybe worse shape than the other side. So I want to get taken care of by replacing both spindles or the entire axle. Just need to figure out which is the best route to go.
