This just started after i serviced the car (full service/wheel rotation/balance/etc), in 2nd or 3rd gear (automatic) the car vibrates hard when its between 100-120kph, when it kicks into 5th gear, it goes back to normal.

Could this be worn engine mounts/axle problems? or could it be my exhaust affecting the engine (after removing the catalytic converter), the exhaust issue doesn't sound plausible due to it being modified for such a long time.

At times it doesn't happen at all, which is confusing me to no end.

Please respond soon.

Most likely CV shaft/axle related.

Dealership is asking for 1900 dollars to fix both faulty axles...

It could be your brake rotors too
