I have a 2014 Viking and it has started pulling hard right in 2wd and 4wd. It seems to go straight for a a few feet then there is a pop/thunk feeling in the steering and it jerks hard right. Then will go further a pop/thunk again is steering wheel and jerk back left. Any help or suggestions? Brakes aren’t sticking. Can’t see how only one front wheel would be sticking in 4wd either. It does the same in 4wd.
