Help! Another Traction Control question

[keebler94]

Here is some backgroundon my 06 Yukon SLT 4WD. Been getting a noise in the front end & traction active on the DIC when pulling out. After reading up on this issue on this forum I decided to take it to a mechanic to tell me which front wheel bearing assembly was giving the trouble. He hooked it up and said the passenger front was losing signal from the sensor. I decided to change out the whole assembly since it has 125000 miles on it. I did the job myself and it is relatively simple to do. But after completing the job, my wife took it out for a test drive. she came back and told me its still making noise and traction active is still happening.
Needless to say i am a bit peeved about this....did the mechanic even hook it up ? did he tell me the wrong side? do I need to replace the other side now?
Any advice would be helpful! Thanks!

Has the other side ever been changed that you know of? At 125k on the clock it`s not a bad idea to change it out as well.

As far as I know they havent been changed. Is there any other possible causes for this? I replaced the one side and didnt seem to make any difference at all. Thanks

One way to tell what side wheel or hub bearing is bad is to weave back and forth on the road while listening for the noise.

When you swerve to the right weight is taken off the right front and the wheel bearing noise should stop and obviously the same for swerving left.

I have used that method for many years and it has never been wrong.

Another way to tell is to jack up the truck and grab the tire at 12 and 6 O clock and try to rock it. If you have excessive play then it`s most likely bad but i have had bad hub bearings that were tight but still made noise when driving so that`s not the best method.

Whenever i have a bearing go bad on one side i always replace both because logic tells me that the other one is sure to follow.
