Gmc Jimmy 2001 ABS Sensors cleaning?

[Andy bra]

My ABS system is starting to act up to a point it really scares me while im parking or something cause they try to push my feet off the break while im going slow. I just got a used ABS system installed about 5 months ago so im hoping its nothing wrong with that.. I need to check how clean my sensors are however i dont know how to get to them Can anyone tell me there exact location. Any ideas recomendations would be helpfull.. even if its i shouldjust take it to a shop instead thank you
ABS light is not on

The ABS sensors are part of the front hub assembly on that truckk. The front is likely the cause. I have a 97 Chev. truck it had the same problem the hubs were over $100 a piece. This is a notorious Chev. problem. The shop will likely charge you a decent amount to do it because it is a bit involved. I haven't heard of any way to clean them.
