My 97 RL was shaking badly too despite new tires & l just had both cv axles replaced and the shaking ended.
You have a warped rotor. It must be trued at a machine shop or replaced.
Your tires probably just need to be balanced.
Steering wheel shakes
roters need turned. 65;
You need an alignment.
Rotors are warped. Have them trued or replaced as necessary. Also replace the brake pads at the same time.
your tires may need to be balanced
Could be in need of a tune up.
This depends on how much your car is exposed to the elements. In areas with poor weather, it will need to be replaced often.
could need a good tune up sounds like it has a miss
more than likely they need balanced. 65;
Need more info like what is the vehicle doing when it shakes, is it idling in park, driving down the road, braking, driving at highway speeds, etc.
