ABS light and humming

[JHolden]

So earlier this week while driving home from work, the serpentine belt tensioner exploded! so after replacing that on the side of the road I now have a new problem to contend with.

This morning on the way to work, I noticed a humming sound start up, with a very slight, occasional vibration. then by the time I got to work (30 miles) the ABS and traction control lights were on. Any ideas?

The front wheel bearings were checked when the truck was inspected about 3 weeks ago. one front was replaced. Could it be a rear hub?

yes check to see if you can rock the rear wheel back and forth (after jacking it up)

ok thanks? are they easier to replace than the front?

Unfortunately the front is easier. The rear likes to seize into the knuckle and is very difficult in most cases to get freed.
