Troubleshooting car problems of pulling to right or left while driving
Car slightly pulling to left or right is usually cause by a mismatch tire pressure on front tire, a wheel that is out of alignment, and a front brake that is dragging. When determining the cause of the problem start by checking the tire pressures on both front tires with the use of tire pressure gauge. Compare the reading against the standard tire pressure set by your car manufacturer, the value is located on the car owners manual or the label adhere on the driver side door. If the reading is different with the standard tire pressure then this causes the problem, to fix this just make the tire pressure on both the front tire equivalent to the pressure set by the car manufacturer.
If the tire pressure of each front tire is correct the next thing to check is the dragging front brake. To check for the dragging brake, you have to drive the car for approximately 20 minutes and stop. Get out the car and touch the rim of each front wheel, check if the temperature of the right side wheel is different with the temperature of the left side wheel.
The hotter wheel is the one with a dragging brake and this causes car pulling while driving. In this case bring the car to a reputable auto shop and ask the mechanic to inspect the side where the brake dragging occurs.
However, if there are no significant temperatures difference between right side rim and the left side rim then is not a problem of brake dragging but rather the wheel is slightly out of alignment. Now, to fix this problem an alignment job will do. Take this kind of problem at once to avoid abnormal wearing of the tire, and prevent car pulling while driving.
