The damper of claim 5 further comprising: a keyway on an interior surface of the housing; and at least one key on each of the second discs, each key projecting outwardly from an outer circumference of one of the second discs to mate with the keyway on the housing. 9. A damper for a power steering system of a vehicle comprising: a housing; a steering shaft inserted into the housing and having an output end coupled to the power steering system; a clutch engaging the steering shaft and the housing, the clutch being biased to inhibit rotation of the shaft relative to the housing and thereby dampen vibrations being transmitted in the power steering system; wherein the clutch further comprises a set of first annular discs and a set of second annular discs, each of the first discs being sandwiched between a pair of the second discs, the first discs engaging the steering shaft and the second discs engaging the housing so that when the first and second discs are biased together the first and second discs are inhibited from rotating relative to each other and the steering shaft is inhibited from rotating relative to the housing thereby dampening vibrations being transmitted in the power steering system; a spring in the housing to bias the clutch into engagement with the steering shaft; and a port in the housing providing hydraulic communication with the power steering system so that an increase in hydraulic pressure transmitted through the port and into the housing overcomes the bias of the spring on the clutch and enables rotation of the steering shaft relative to the housing for steering of the vehicle. 10. The damper of claim 9 further comprising: a spline portion on the steering shaft being inserted into the first and second discs; at least one tooth on each of the first discs, each tooth projecting inwardly from an inner circumference of one of the first discs to mate with the spline portion of the steering shaft; a keyway on an interior surface of the housing; and at least one key on each of the second discs, each key projecting outwardly from an outer circumference of one of the second discs to mate with the keyway on the housing. 11. A damper for a power steering system of a vehicle comprising: a housing; a keyway on an interior surface of the housing; a steering shaft inserted into the housing, the steering shaft having a spline portion and an output end coupled to the power steering system; a clutch engaging the steering shaft and the housing, the clutch being biased to inhibit rotation of the shaft relative to the housing and thereby dampen vibrations being transmitted in the power steering system; wherein the clutch further comprises a set of first annular discs and a set of second annular discs, each of the first discs being sandwiched between a pair of the second discs, the first discs engaging the spline portion of the steering shaft and the second discs engaging the keyway on the housing so that when the first and second discs are biased together the first and second discs are inhibited from rotating relative to each other and the steering shaft is inhibited from rotating relative to the housing thereby dampening vibrations being transmitted in the power steering system; at least one tooth on each of the first discs, each tooth projecting inwardly from an inner circumference of one of the first discs to mate with the spline portion of the steering shaft; at least one key on each of the second discs, each key projecting outwardly from an outer circumference of one of the second discs to mate with the keyway on the housing; a spring in the housing to bias the first and second discs into engagement with each other; and a port in the ho using providing hydraulic communication with the power steering system so that an increase in hydraulic pressure transmitted through the port and into the housing overcomes the bias of the spring on the clutch and enables rotation of the first and second discs relative to each other and of the steering shaft relative to the housing for steering of the vehicle. 12. A power steering system for a vehicle comprising: a steering wheel; a rack and pinion assembly coupled to the steering wheel; a hydraulic pressure pump; a damper coupled to the rack and pinion assembly and in hydraulic communication with the pressure pump, wherein the damper further comprises: (a) a housing; (b) a steering shaft inserted into the housing and having an output end coupled to the rack and pinion assembly; (c) a clutch engaging the steering shaft and the housing, the clutch being biased to inhibit rotation of the shaft relative to the housing and thereby dampen vibrations being transmitted in the power steering system; and (d) a port in the housing providing hydraulic communication with the pressure pump so that an increase in hydraulic pressure transmitted through the port and into the housing overcomes the bias of the clutch and enables rotation of the steering shaft relative to the housing for steering of the vehicle. 13. The power steering system of claim 12 further comprising: a spring in the housing to bias the clutch into engagement with the steering shaft. 14. The power steering system of claim 13 further comprising: a piston in the housing and coupled to the spring so that upon the increase in hydraulic pressure in the housing the piston compresses the spring and releases the clutch to enable rotation of the steering shaft. 15. The power steering system of claim 12 wherein the clutch further comprises: a set of first annular discs and a set of second annular discs, each of the first discs being sandwiched between a pair of the second discs, the first discs engaging the steering shaft and the second discs engaging the housing so that when the first and second discs are biased together the first and second discs are inhibited from rotating relative to each other and the steering shaft is inhibited from rotating relative to the housing thereby dampening vibrations being transmitted in the power steering system. 16. The power steering system of claim 15 wherein the first and second discs are juxtaposed in face to face relation to one another. 17. The power steering system of claim 15 further comprising: a spline portion on the steering shaft being inserted into the first and second discs; and at least one tooth on each of the first discs, each tooth projecting inwardly from an inner circumference of one of the first discs to mate with the spline portion of the steering shaft. 18.
