Q: VSA light is on

Hi, my Honda Accord 08 recently began showing VSA light and the triangle light beside it, whenever i start the car. And i noticed the car would jerk in P while warming up. I had my mechanic check and he replaced two faulty nozzles. After the repairs, the jerking stopped, VSA warning light stopped too. However, when I drive in the speed range of 40 to 80km/h, the VSA light comes on again BUT if i speed upto 90/100 km/h and above immediately i start the car and begin moving, the light wont come on. A local mechanic told me i need to do wheel balancing and alignment, because my upper arm on one side was replaced. I don't see that as the problem because the tyres were not swapped. Also, my hub had an issue before car was taken to replace nozzle but the mechanic couldn't find a good part so he changed the bearing instead. Can any or both of these be the cause (ie change of bearing and lack of doing wheel balancing) Thanks very much.
