This owner complained of leaking rear axle seals, so we quickly changed them. We found that the owner, upon reassembly, had failed to adequately tighten the various nuts and bolts in the rear axle, and believed that it was due to this general looseness that the seals had ended up leaking. We were wrong. Our owner only got half way home before the real problem evidenced itself. We've now changed the left wheel bearing and expect that this will solve the problem!
Something's quite wrong, as I continue to be unable to post pictures. Maybe tomorrow?
