Right fron tire pulls to right. Torsion bar ? How much. ? on 1994 Mercury Grand Marquis

My right front is pulling to the right. maybe a bad tire or a bad torsion bar ? How much for the torsion bar if it needs to be replaced /

This vehicle has a coil spring suspension, not torsion bar.

For a pull to the right, have the wheel alignment checked for caster angle differentiation. If it's more than 1 degree off (to the negative) right verses left, it will cause a pull for sure. Have that adjusted. Make sure camber and toe are OK too. Secondly, have the tires swapped right to left - see if the pull follows the tire and now it pulls left.
