My 100 series steering vibrates excessively

Bad tire, worn wheel bearing, worn/loose suspension, worn bushing, worn/loose tie rod, warped rotor (would feel mainly when braking). We can play guessing games all day, you'll never know until you take it to an alignment shop and have it inspected. Something like a tie rod can go suddenly while driving and cause a serious accident.

Hi Thanks for your response,I should have stated that I’ve already done most things you mentioned also replaced rack it’s intermittent which is frustrating
