•Steering wheel pulls to one side intermittently
•Decreased handling stability at high speeds

Diagnostic Steps

1
Inspect tire pressure on all four tires and adjust to manufacturer specifications.
2
Visually inspect tires for any signs of damage, uneven wear, or bulges.
3
Perform a wheel balance check on all tires to ensure proper weight distribution.
4
Check for any loose or damaged suspension components (e.g., control arms, bushings).
5
Inspect wheel alignment settings to ensure they are within manufacturer specifications.
6
Test drive the vehicle at different speeds to confirm when vibrations occur.
