my 1990 eclipse started pulling to the right when I let off of the gas

Any noise? Wheel bearing normally will give a growling noise(like an old 'prop' plane flying overhead) from 20-up and then continue growling while you slow down , typically to a slower speed than it started at. IF no noise , I might suspect contaminated brake fluid , failing caliper or hose , all of which can be checked , and tested(caliper and hose) , BEFORE replacing parts. Tire pressure/worn suspension next.
