Does your car still pulls even after adjusting your wheel alignment? Many things can make a car pull even if the wheels are properly aligned including suspension issues, braking faults, unequal shock absorber height, tyre pressure difference, bending roads, etc.

A clearance from any part of the suspension such as tie rod, weak bushings, stabilizer linkage, lower/upper arm, hub bearing can make the car pull right or left. To be sure of this, have your car lifted with a jack from the side rail or chassis, then shake the tyre vertically (by holding the tyre top and bottom) and then shake it, if you fill any clearance it’s probably the hub bearing. Shaking the tyre horizontally (by holding the tyre sideways), if there is clearance it’s probably the tie rod or lower arm.

If you notice your car pulls either left or right when you step on your brake pedal, then the brake disk needs to be checked. Worn out brake pads too can make this happen.

Your front shock absorbers need to be of equal heights to keep your steering straight. Leaked shock absorbers on either side can make it lose its hydraulic thereby altering height. This makes the car slightly bend to towards the faulty shock absorber and also make your steering bent even if the car doesn’t pull.

The front tyres must be of equal pressure if you must keep your car straight. Most cars use between 32psi to 35psi as recommended pressure. If either of your front tyre is lower than normal, it may cause the car to pull towards that side when driving.

Some roads are usually bent by construction because of drainage issue. When on such roads, your car may tend to pull towards the lower side of the road, so do take note of that.

If after adjusting your vehicle’s alignment you still notice a pull to either side (not both sides), note that these conditions must be met for your car to move straight:

All 4 wheels must be pointing the same direction
All 4 wheels must offer the same rolling resistance
The steering turning angle must be the same (to each side)
To be sure your 4 tyres are pointing the same direction, bend and look at the tyres from the front at each side and see if the front tyre is parallel with the rear tyre.

Make sure your front tyres have the same tread pattern so they can give the same rolling resistance. Having different tyre tread pattern, different brands or worn out tyres can make the car to swerve to either side while driving.

To check your steering turning angle, keep your steering at the center, turn to the left while counting the turning angle to the end, bring the steering back at the center, then turn it to the right while counting the turning angle again. If there is a huge difference in turning angle for instance if turning to the right has an added 450, your car steering may not be straight when driving even if the car manages to move straight.
