did u have the tires rotated/ balanced recently? why i ask is my sister had her 90 corolla tires rotated and balanced like 2 weeks ago. her steering wheel started to wobble n she had a bad pull to the lt. i took her car in this weekend to the same place and i asked them to rerotate them and rebalance. then i asked them to tell me which tires were not balanced, out of round and which rims r bent. turns out she had a bent rim on the dr front and an unbalanced tire on the dr rear. so the rerotate and balance got rid of the wobble and pull. still has the vibration but a new rim should fix it. she has plenty of tire tread. she has new rotors, 1 axle and 1 bearing.

being front wheel drive u will notice bent rims on the front axle more then the rear. she is getting a replacement rim for the bent rim. its slightly bent and holds the tire but its bent enough to pull the steering wheel and make the wheel wobble on its own.

if your tires r worn replace them. most have tread markers on them u can feel them as u drive down the road. u can see them. u will notice braking isnt as quick or smooth. u will hear squealing as u turn. u will start to collect road hazards. nails esp. u will feel most road imperfections and it will feel like u need front end parts and u dont. new tires will feel much better on the road.
