hell I have a 2002 chevy blazer 4x4, this evening I noticed that my abs light came on for a second went off, I **** vehicle off had a coffee got back in started it up, abs light was on drove half a block it went out. put scanner on it and pulled a stored code c0223 and code 0265, when I bought it 3 weeks ago the guy I bought it from said both front wheel bearings where changed.. I dont have proof of that, but what can I look for.. havent had it long and only noticed it do it this once.. any help is appreciated, thank you

 

If you have a lug nut that is included or chrome, then take one off and the stud should have little to no rust on the end of it not the thread. If you have a cap over them, remove it and the hub itself should be "clean". Did he say how long ago he did the work? I

 

he told me it was done about a year ago, I do know my shocks are old and pretty done in and my wife just had the same erratic wheel speed code on her cobalt and once shock was changed fixed the issue, so I'm wondering if for the erratic wheel speed could be caused by shock absorber in the front? dirty sensor? i will asses more tmrw when I climb under to check harnesses etc, thanks for your reply.
