could be a sensor but need a scan to be sure. Cannt say whether you can do it yourself because not familar with your skill level.

When the ABS light came up on my Grand Am it turned out to be a front wheel sensor. Like yours, the front wheel speed sensor is built into the hub and can only be replaced as a unit. I didn't change it until the second front sensor went since that resulted in loosing my ABS, cruise and traction control.

You'll need to get it scanned to find out which one is faulty.

If you have the tools and the mechanical aptitude, you could be able to do it yourself. But the torque value required is beyond the 1/2" drive torque wrenches (around 280 lb-ft). When using a 1/2" drive you'd also need to use a torque multiplier. Not a problem if you have a 3/4" drive torque wrench.
Although when I did mine 5 yrs ago, I just turned my torque wrench past the 250 an equal number of turns to get my value, along with a 4 ft bar for leverage.

You'll also need a hub puller handy. After that length of time the hub can be siezed on the shaft.
