my 02 monte trips the trac control system almost every time i go from a standing start [growling noise] even in reverse [rarely] when driving in stop and go a lot of times the abs kicks on like i''m on ice and i almost run into people. about 6 months ago the gm dealer scanned the car and replaced the right front hub with internal sensor. car worked fine for 2 months then this problem has gradually gotten more frequent.did the sensor go bad after 2 months I hope some gm service aces see this and give me reply. thanks in advance.

well i''m not an ace but buy the time i get done with my olds alero i will be , strange to here a monte is having this problem, what i have seen on most web sights is it doesnt matter high dollar or low dollar hub bearings/internal sesnsors dont last very long on my 3rd hub/bearing change with this olds, first one i got autozone, timken 1 year waranty. its was april when i put it in, end of june trac lite, service vech soon lite, and the abs lite would come on every so often, bought a national brand bearing/hub, for the opposite side thinking that would fix it, nope!! ended up buying a actron brake scanner ,it told me the right wheel speed sensor(timken) accesive vibration! ,put the old one in from the left side back in until the new one from autozone came in, not once did any lights come. still put new one in and kept old one for spare, one thing i hope that your mechanic did is replace the drive axle nuts with new ones, gm has upgraded to wider based nut takes less torq(173 ft lbs) compared to the old style(284 ft lbs) the new style part number is 10289657, it is light gray in color.
over tighting, could cause problems,might be a different hub going out have them scan it again! should be under warranty if its gm brand.

My abs light and traction control would kick off when I''d hit my brakes. I know what you mean like you''re floating on ice. Ended up taking it to the dealer and the wire assembly and passenger''s side hub was bad. The wires were brittle due to heat and the wire to the control sensor was completely snapped off! Check the sensor and the wires running to the hub to ensure they''re still there/working. Otherwise, that wire assembly might need to be replaced. Cost me about $550 and that was with a discount...........
