2002 Cadillac Deville Suspension problems

Front wheel bearings have dangerously failed prematurely two times in 113,000 miles. Failed dangerously at 60,000 and 113000 miles. This resulted in front wheel shimmy (shaking steering wheel excessively) at high speeds and at all times when braking. Felt like I was loosing brakes when braking down a hill. When car is jacked up wheel rocked back and forth about 2 inches. Seems to me that this is a common problem on gm cars that use the cartridge type of wheel hub bearing assemblies as indicated by numerous post on the internet and my personal experience as an auto mechanic. *Tr

2002 Cadillac deville, clicking in right rear wheel bearing. Dealing checked bearing, found it to be bad, and noted that left front was also going bad. Rear bearing replaced, front bearing tighted, dealer suggested periodic checks, may need replacement in future. This call is less that 3 years old, 60k miles, bearing should not be going bad. This car was not in an accident, nor curbs struck, not was it setting un-used for any length of time. These are scenarios the dealer tried to explain to me why wheel bearing went bad with 60k miles. I explained that neither of those scenarios were experienced by me/this car.L *jb
