WHEEL-WOBBLE

LOSS OF CASTOR SETTTNG. The most common cause of wheelwobble is a loss of the tilt or castor setting of the front axle, which is always tilted slightly backward so that the wheels will tend to swing back to a straight-ahead position after they have been turned to one side or the other by means of the steering mechanism. This tilting of the front axle is also of benefit in that it lessens the shocks and jarring caused ISy the front wheels striking irregularities in the road. The most frequent reason for loss of front axle tilt is the settling of the front springs, and its effects are much more pronounced with modern cars because of the use of balloons tyres and very sensitive and light steering apparatus But investigation has also revealed that the settling.of the rear springs will aggravate the condition: The common remedy is to insert thin wedges between the axle and the front springs, and so to restore the original degree of tilt, but motorists are not advised to undertake this experiment haphazardly. While it is .possible by a process of trial and error and the experimental use of wedges of different thicknesses to obtain the desired results, it is far better to .have the work done at a well equipped service station.
