I'm working on my uncles 07 Aspen and here the story goes...
He complained of a wobble in the front end I was thinking it may have been a wheel bearing come to find out My brother-in-law didn't tighten the lug nuts on the driver side front wheel so while he was driving it about 35 the front wheel came off and the rotor ground into the road. The vehicle didn't touch the ground other than the rotor so he got it towed to my house I replaced the wheel bearing and got the wheel back on I only just start the truck and find it in limp mode. The ABS light has always been on but it's still drove fine still I had a code c2200 and replaced the ABS unit as well as the throttle body and pedal assembly. It's showing no codes but still has the damn lightning bolt. Any help would be appreciated about to give up.
