Front Suspension Hub problems of the 2000 Ford Focus

Got my daughter her first used car from a dealer, which I should had gone with her to check it out first since an 18 year old would most likely not know anything much of a car besides driving it. You would think buying from a used dealer is safer than buying out in the street. So when we took it out of the lot noticed engine tremble and suspension noise, (too bad no lemon law on used dealer selling this type of cars). After diagnose the engine produced a catalytic convert malfunction code. Also after inspection the Focus needs all four suspension struts. A month later that other suspension noise resulting almost in a accident from a back wheel shaking which came from a back wheel bearing which hub nut was just about off, which would had caused the wheel to come off. I did a search and this are all common problems with the Focus and I believe there was a recall for a back wheel issue. The bad news is that after a while of the recall being issued it is voided or only specific VIN numbers are considered effected ????. The latest encounter is the steering column locking and the key not being able to unlock it. The worst part is that the ignition cylinder would have to be drilled out to be replaced (very interesting since is the first time I seen that). I'm noticing from my experience with Ford vehicles that although in my opinion there engine and transmission are a bit better than most vehicle, is the little parts that one have issues with that ends up costing the most, just saying. So why is it that with many complaints and known issues from previews model years Ford has not attempt to resolve the issues. I bet there would be many other people out there complaining if only they new they can complaint, the question is, is anyone going to do something about it!!!.

No special events took place to cause damage. I am at 75k miles. Both right wheel bearings have gone bad (both front and rear) and requires the entire hub to be replaced at $350 each. Rear hub almost caused tire to fall off while driving, caused brake failure and abs failure. Also required rear brakes and abs chip to be replaced.

A "grinding" noise was heard when brakes were applied. Inspected brakes - found no problem. Within a few days the grinding noise turned into a constant "growling"/ "rumbling" noise. Re-inspected wheels/ brakes and found drivers side rear wheel to be loose / wobble (lug nuts were properly torqued). Closer inspection revealed that the hub/ wheel bearing assembly had "significant play". While the car was jacked up the drivers side rear wheel would go from "easily spun to nearly locked up". The "rear bearing retaining cap recall" was performed on this car years ago - we are the original owner of this car.
