did the hub bearings....
 

today, knocked out the front bearings on my 2006 HHR LT. 116,000 miles. not too bad except for trying to get the old hubs out.....had to resort to using a loaner slap hammer. could not have done this job without this tool...made sure to make use of anti-seize when putting things back together....

I use one of these

an impact hammer is not a bad way to go........maybe my next air tool to p/u..

HF is a great option for those that use a tool like this once in a while.
