You might say I'm a little gun shy on the subject. Not too many years ago, I had a car fire caused by, I believe, a cheap replacement axle shaft. This was a solid axle GM, not a TR and IIRC the shaft was around $150. But on that axle, the wheel bearing runs directly against the shaft, which is obviously supposed to be hardened and ground in that area. The new shaft was not hard enough (or something), and the bearing surface "went away" in just a few thousand miles. We were on vacation when the brake started dragging (because of the shaft being out of position), so it got the drum good and hot, then started leaking gear oil into the overheated drum.
Had a rather interesting time getting everyone out of the car (including my disabled son), then all our luggage, then trying to jack the car up so I could get under there to douse it with water. Don't know if the water did any good, but it did eventually go out without doing any lasting damage; just seconds before the fire department showed up. Pretty well ruined the vacation, not to mention the 3 week delay in getting back home.
Both shafts had been replaced at the same time, with the same brand of course; and the other side failed shortly afterwards (although not nearly so dramatic). Put in some genuine GM shafts (at over twice the price of the others) and no troubles since.
