Without question I do not trust the quality of bearings made in Asia and repackaged for sale in the States. Of course where are you going to find "real" bearings now days unless you stumble upon some old, unsold stock from a defunt parts store?
I found out yesterday I couldn't buy name brand (German company) sissors anymore as all the name brands have "made in China" on the carton. Try to buy U.S. made rubber bands, thumb tacks, etc. (and people want to know what happened to the economy!)
But a new insite on the bearing problems. 18 months back I saw white cords showing on one of my Mustang's tires. Couldn't obtain a goodrich T/A from stock (they are now made in Mexico or Asia) and bought a "good" used tire so I could get to work.
As soon as the tire hit the gorund I started to hear bearing noise but that went away in two weeks. I did give some thought to the uesed tire being shaped/worn through use on the front end of another car.
The noise stopped and I never got around to changing tires. After some tight left turns the noise came back, lasted a few weeks and vanished. Three times.
Last week the used tire finally would not hold air and I finally got the new tire installed. The noise had returned and I had checked the bearings and brake calipers (thought one had failed to retract evenly) and found nothing worth replacement.
Two days after the new tire was on the car the noise stopped. That lead me to taking a good look at the used tire, it was worn at an angle across the width.
Okay, that's a good lead. But something you didn't mention, are you running stock wheels made for your Falcon? I used to laugh at the guys who put extreme reversed wheels on their car to make their "ride" look like a Hot Wheels product and then complain because the wheel bearings failed.
If you are not running the stock wheels you might have an alignment problem. |
