Can you just change the front wheel bearings on 2000 Buick Regal or do you have to replace the entire hub assembly?
I have not work on Chevy Ttrailblazer so far. I have Chevy Sonoma 2001. My experience with it at the end was, to replace the the complete "hub unit." My problem was with the "Bearings wear" and not the sensors. Though the bearings look good they were "worn out some after 35000 miles." I had one wheel taken out 4 times and put it back. Finley I did replace the "Hub" with a new one…
To change front wheel bearings on a 1976 four-wheel drive GMC Sierra, you have to use the proper tools. Either by a mechanic or yourself; but you are required to know the basics. Being that these bearings are sealed and cannot be repacked with grease. It is important to replace the worn bearings, with the new ones. Before they damage the hubs.
