ACDelco 20938122 Original Equipment Sensor Review

ACDelco 20938122 GM Genuine Equipment ABS rear wheel speed sensor worked great to repair the ABS, traction control and stability control on my 2009 Suburban.

Great item, solved my problem. Keep in mind that swapping can be tricky. The original part fails because the hole it goes in rusts and the part breaks, making it difficult to remove. I had to carefully drill mine out. So if you don't like it, I can leave that to the professionals.

You don't even need to dismantle the wheel. The T-30 was too rusty and boltless. After soaking it in penetrating grease, I had to cut out a screwdriver slot and replace it with an M6 - 1.0 x 12mm stainless steel hex socket. The ABS lights went out immediately after the replacement, I didn't even have to clear the code. Works great in Suburb 2014

So I got the horrible message "Service Stabilitrak/Service Traction Control" on my 2008 Suburban along with the traction control and ABS lights on the dash at the same time. Bought an Ancel FX2000 scanner. I scanned the ABS and got the right rear wheel speed sensor code. Bought and replaced on the street without dismantling the wheel. The installation isn't that bad, although it took me more than 5 minutes. Stronger parts connected the proximal end of the sensor to the car's wiring at the top…
