At highways speed the wheel base seems to wobble a bit and make a lot of noise

Hi skittish06,

I suspect the wheel bearings need some attention. Jack up vehicle and check for side play of wheels and abnormal noise when turning them by hand.

Hi,

Does the noise seem to be a whining like sound? If so, does it change pitch when making turns? If it does, then suspect a wheel bearing is bad. Here are specific directions for testing the bearing for excessive end play. The attached pic correlates with the directions.

1. Raise the vehicle, and support it with safety stands in the proper locations.
2. Remove the wheels.
3. Install suitable flat washers (A) and the wheel nuts. Tighten the nuts to the specified torque to hold the brake disc or brake drum securely against the hub.

See pic 1

4. Attach the dial gauge. Place the dial gauge against the hub flange.
5. Measure the bearing end play by moving the brake disc or the brake drum inward and outward.

Front/Rear:
Standard: 0 - 0.05 mm (0 - 0.002 in.)

6. If the bearing end play measurement is more than the standard, replace the wheel bearing or the hub bearing unit.

Keep in mind, a bad bearing can make noise and not have excessive play. If you notice that the sound changes when making a turn, suspect this. If it gets louder when making a right turn, suspect the front left bearing is bad, and opposite for a left turn.

Try these tests and let us know what you find.

Take care,
Joe
