Wishbone when i drive my 1996 fiesta at 60 the drivers side wheel shakes like mad, ive got it bookd in for a new wishbone. can i cause any damage by driving it?

The power steering belt could be slipping or the pump is going down

Wishbone bushes or steering rack adjustment

Sounds like you need a wheel balance and alignment.

get under the vehicle (use ramps) and check all linkages for movement pull push on the anti roll bar links, pull push on steering rack and pinion and linkages, any excessive movement, jack each wheel at a time, using a bar check the lower wishbone joints for movement, get the bar in the gap between the wishbone and lower part of the shock. and pull down, if any movement in ball joint up and down replace. while wheel on vehicle check for movement in bearing you will feel a tiny amount not much but pull and push on wheel with opposite hands on 12 o'clock and 6 o'clock and do the same at 9 and 3. now with both wheels off the ground but with the tyres still on, have some one holed one wheel and push pull on wheels each side there should be even movement between both wheels, if everything is fine with the the steering linkages and this dose not feel or sound right then this could be the problem also to add if the inside and out side of the tyres are wearing then the tyre pressure is wrong and needs adjusting to the right tyre pressure .

Why drive side bearing could be a bad other.balance yes, tie rod could be bad.

jack it up and spin the wheel ,could be rim or it could be a deformed /damaged tyre

Sounds like the tire is starting to delaminate. How old are the tires? If you take the wheel off the car, you may be able to see a bulge in the tread. What is happening is the thread is starting to come loose from the steel belts underneath. It can happen to any tire with age. It's a serious problem: eventually the tread will separate completely, while you're driving, and throw the tread all over the place, most likely damaging your car. It could even cause you to lose control, or it could hit someone else, whatever. Gotta replace it, and soon.

If it's just the one wheel, not a shimmy in the whole car, I'd say the tire is going bad. It could also be a loose/worn out balljoint: with the front wheel(s) off the ground, try to move/shake each wheel. If there is any 'slop' in the wheel, you have a bad balljoint. Which requires professional repair, if only for a new alignment once the work is done.

Good Luck!

Front wheel drive cars have CV joints in the axles to permit the wheel to turn for steering. The CV joint is basically a universal joint on steroids. When they ware out it can cause this type of condition.

Well even though you had the rotors turned, they still could be warped and causing the car to shake at a high rate of speed when the brakes are applied. My suggestion is to replace the rotors asap.

it may be bad tires or you need an alignment done
