Hi could any one help, I recently hit a rather large pothole (at night ) and since then the steering wheel rocks from side to side, when driving at low speeds. I have tried it with no hands on the steering wheel and it jumps from side to side.
I am hoping its a small thing like tracking but is there anything I can do at home to see if it is anything else?
Thanks in advance for any help
