Have the wheels balanced
I would check tire balance and check for warped rotors. Check tires for blisters and check the steering linkage for worn parts. Check the shocks and the engine to see if it is not firing all cylinders.
Shakes, quivers, fluctuates, reverberates, trembles, resonates, oscillates...
One or more cylinders are firing badly or not at all. It needs a major tune-up.
you might have a router or caliber gone
check your wheel bearings and if they're ok check your cv joints by jacking up the front of your car and rock your tires forward and back to see if they clunk or shake pretty good
If it shakes all the time it is a tire/wheel problem. If it only shakes when braking then it is a brake problem.
Its either timing or fuel intake problem.
It is probably missing. Have it tuned up and a compression test run on the engine.
i dn't know. when you find out let me know..
My 97 RL was shaking badly too despite new tires & l just had both cv axles replaced and the shaking ended.
If your car vibrates when you are braking, you might have pads that have worn unevenly. You can have the brake pads inspected to see if there is wearing on the drum or if you have a problem with your rotors.
My camaro did the same thing minus the grinding and it ended up being the control arm. Although yours sounds like wheel bearings because of the grinding which can also cause vibrations.
there could be several reasons for this problem the most likely being an alignment problem, if it occurs only when your braking it is probably warped rotors or out of round drums depending on your braking system bad spark plugs or wires
