The Requirements Before Checking The Front-end Alignment

This brief automobile tutorial will outline what the preliminary requirements that are prior to a front-end alignments check are; then it will further make a list of its inspection routine.

In order to be able to check the front-end alignment, all checks must be made with the automobile level and with the weight of the automobile on the wheels. No load on the vehicle is usual, but in some cases a load is specified.

Before any attempt is made to check or adjust caster, camber, toe-in, king-pin inclination, or toe-out, an inspection routine should be made on parts which influence the steering of the automobile.

The inspection routine which must be carried out prior checking front-end alignment is as follows:

(1) Inflate tyres to the recommended pressures

(2) Check the adjustment of the front-wheel bearings, and correct if necessary

(3) Also check steering-gear adjustment

(4) Check the runout of wheels and tyres, and correct to 1/8in. if necessary

(5) Also check the shock-absorber action, and correct if necessary

(6) Check for looseness at the king-pin; if found excessive, it must be corrected as well before alignment readings will have any value

(7) Check for looseness of track-rod ends, and replace if necessary
It is also necessary to check the front leaf springs (if fitted) and tighten U-bolts

(8) Check the wheels and tyres for balance, and correct to specification if necessary.


(1) Camber:- A vertical alignment of the wheels of a road vehicle with positive camber signifying that the wheels are closer together at the bottom than at the top.

(2) Caster:- A wheeled assembly attached to a larger object at its base to facilitate rolling. A caster usually consists of a wheel, which may be plastic, a hard elastomer, or metal.

(3) Toe-out:- This is the front of the wheel pointing away from the centerline of the vehicle.

(4) Toe-in:- This is the front of the wheel pointing towards the centerline of the vehicle.
