I have a Dodge Charger 5.7 2016 (automatic transmission)
It shakes (the car) at 80-90 mph
its not like body problem no the car actually shakes a little if i remember correctly
the steering wheel does not shake
I can also feel the vibration in the throttle and brake pedal
the vibration happens even when gas or brake is not pressed
however at 90 mph when brakes are applied the car shakes even more violently
the problem started after I repaired things in front
I am not sure if they are suspension related but i think they repaired rods or something (replacement) because my car used to make strong sound upon sudden break (now gone)
back to present problem, I tried braking strongly at low speed I didnt notice abnormalities
I tried revving in neutral no abnormalities
I balanced the wheels but that didnt fix the problem
and My front and rear tires performed alignment and caster adjustment procedure respectively
Its a mystery where the problem is; my rear tires are fresh new and the front ones slightly unevenly worn on inner side
again, steering wheel does not vibrate and brakes and throttle pedals also vibrate a little during the vibration
ps: car service due this week
appreciate any help
