Hello all, I looked to see if there was a thread related to my problem but I haven't been able to get an answer. Several weeks ago I replaced my Front left wheel bearing as it went bad. Today, I was driving and was showing off the car to a friend so I put it into tapshift mode and got on it in 1st. When the car hit 4k rpm, it started bucking as if someone was stomping on and off the brake pedal. I backed off and dropped her into second and tried her out again. Once I reached 4k, it started to buck again in 2nd. I backed off right away and then my trip computer said Traction and Stability management was disabled and needed to be serviced. Is there a possibility it has something to do with the new wheel bearing? I checked the connection and it isn't lose or anything. Came back and drove her again and didn't have the problem. Is this a common thing or is it something I need to worry about happening the next time I get on it? Any help would be great!
