Fixed BMW triad of lights. However the rear wheels skid or lock up now.
I had BMW triad of lights for my 2008 X3. I replaced the transfer case servo motor's plastic gear that was chewed. BMW triad of lights went away.
However, now I noticed that if I accelerate or brake at low speeds with steering wheel turned left or right, then both or one of the rear wheels skid or lock up (ie I feel it by car jerking a little bit). This does not happen if I brake or accelerate in straight line.
I also replaced all 4 tires. The problem did not go away. Though Costco tire center recommended that I check alignment because tires were not evenly worn.
The questions I have:
1. Maybe this skidding/locking up is normal for bmw x3? I just did not pay enough attention before?
2. If it is not normal, then how to troubleshoot further?
