ABS Light

Check for brake fluid leak too

Mr. 10K

Changed out the sensor, no problems since. Can't see any fluid leaks.

OK. so I had something similar a while back. The main thing that caught my eye is when you state you are pulling a trailer. I had the same issue with the ABS coming on. Months of investigating and it ended up being the gear and pinion in the rear diff was completely broken (only after a heavy, long haul tow). Drove around for quite some time with it broken and had no idea. Pulled off the rear diff and the gear was completely broken.

Geez! Really didn't need to hear that! Might take a peek at that this weekend.
