Back in the mid 70s, I got a phone call about 2:30 a.m. from my brother-in-law. They, him, my sis, and 3 children, were broke down about 50 miles from where I lived. On the highway, too far from town to walk, very little traffic, and Sunday morning. I drove to the site. He had a Ford pickup with a camper, with a little Jon (?) boat on top, and towing a trailer with an old Lincoln welder to power the a/c in the camper. They had been fishing/camping down in south Texas and were returning to Ft. Worth. The passenger rear bearing 'went', snapped the axle; the wheel was about 50 feet behind the truck. We got the old axle out of the rear end housing, found the race for the bearing broken and part of it welded to the housing. Tried to chisel it out, but wouldn't budge. Waited a while for auto supply to open in the town, about 8 miles away. Bought a little rotary file, bearing, seal, and grease. The auto supply people called a wrecking yard owner, who came and sole us a used axle. I happened to have a little a/c drill motor and the Lincoln welder supplied the power. That little rotary file cut that bearing race out of the housing! Was very careful and didn't nick the housing enough to cause trouble. Got everything installed, and they were on their way. He kept that old truck with the camper for several years and never had trouble with the bearing we replaced, so I guess we did a decent job! I got home a little after noon that day.
