Opel Rallier since 1977
Is the wear/galling on the axle shaft or on the outer surface of the axle bearing's outer race? The axle bearing should not easily pull off of the axle shaft. Are there witness marks of the bearing turning against the retainer plate?This time, I spent time inspecting the mating surfaces and found both the axle flange and the housing surface to be a bit scored, and some rough stuff still on the axle portion.
If there is enough gap between the axle bearing's outer race and the axle housing, you might get it in there more snugly with a ring, or partial ring, of thin steel shim stock. Sealing such a ring would need that RTV. Sleeve retaining compound would work great..... but you'd likely not every get the bearing out again! There might be some other compound that would fill that gap well, but not be so permanent.
