I have Honda Grace 2016 car with 105000 genuine mileage. few months ago some noises started when hitting pot holes and when driving damaged roads. when checking with my mechanic he suggested a full suspension repair as all parts are original and already completed 100000 km. all worn parts replaced including 4 shock absorbers with shock mount and related parts, Complete steering rack, balance bar bushes, two links, lower arm bushes, caliper pins, after repair he confirmed there are no any worn out parts generate noises. Unfortunately there is still knocking noise when hitting pot holes. mechanic failed to find any reason he suggest replace both front CV axles as there is play on inner CV joints.( He says bearing or CV cup worn out)
1. Is there knocking noise generate when hitting pot holes if inner joint worn out?
2 is this is a common issues for this particular car model and where would be the cause?
Any one has a idea i highly appreciated
