Swerves alot while driving

Something seriously loose or worn:

- steering box mounts
- steering column universal joint or end clamp
- steering box inner ball joints
- tie rod ends
- outer ball joints
- wheel centre hub nut
- wheel stud nuts

A simple test is to jack up both front wheels and place the vehicle on axle stands. Then have someone hold the steering wheel, grab a front wheel at the 9-and-3 o'clock position, and shake it hard in and out. If you can feel slack or looseness, or the person holding the steering wheel can, you have a dangerous fault which should be fixed ASAP.
