4x4 high light flashes 8 times???????

[aimeagle21]

Hello, I just had my 04 explorer in the shop last week for new wheel bearings. Now the abs light just came on a couple of days ago and the 4x4 high light flashes 8 times every minute or so. Any ideas as to what is going on? Thanks!

Sounds like the shop screwed up one of the wheel speed sensors. Or, if they installed new wheel hubs with new sensors, one of the new sensors is ng. Did they do both front bearings?
