Hi all, i drive Hyundai Avante. All was fine and great with the car till i hit a fist-size rock, which both left front & back wheels went over at around 90km/h, along PIE 1 month ago and nightmare starts.
Damage is cracked rim and puncture tyre.
After changing new rims and replace 2 new tyre (2 tyre can be reuse) and wheel alignment and balancing done plus 2x front suspension changed, i notice the car vibrates once hit 80km/h and the vibration fade away after 85km/h. Beyond 85km/h can still feel slight vibration.
The vibration is felt most at seat (butt) area (nothing on steering wheel) and can be heard as a low humming noise like a out balanced air con compressor.
Car mechanics said it's my gear box Read up on internet suggests drive shaft or CV joint worn out. Called to Komoco for diagnose will cost up to $180! Other than this high speed vibration, everything feel alright.
Appreciate any advice, please.
