1) Hard Steering:- This is neither rare nor common but can be found in automobiles of any type, brand, or model. If a hard steering is noticed in a vehicle, the probable cause could be that the tyres are worn and need to be corrected. Another probable cause could be that there is a burst or flat tyre which needs to be figured out and fixed. Another probable cause could be that there is a low tyre inflation pressure which needs to be corrected. Another probable cause could be lack of grease in kingpin and steering linkage; grease should be applied.
2) Pulling To One Side While Steering:- If you notice your vehicle pulls to one particular side while steering, the cause could be that the left and the right tyres are of different sizes and needs to be corrected. Unequal tyre inflation pressure could also be the cause and such cause should be adjusted. Another possible cause could be the loose in wheel nuts which need to be re-tightened. The load in such automobile might weigh in one side than the other and that should be balanced. Another probable cause could be due to the broken spring leaf, and if that is detected to be the cause, a replacement for the broken spring leaf should be made.
3) Shimmy Steering Wheel:- Unevenly worn tyres could cause a shimmying steering wheel; the tyres need to be replaced. Unequal tyre inflation pressure could also cause a shimmying steering wheel and in such case, adjustment should be made. Loose in wheel nuts could also cause a shimmying steering wheel; the wheel nuts need to be re-tightened.
NOTE:- It is always advisable to visit your local mechanics and pay them well. A healthy automobile assures safety of lives and properties.
