I hear it as soon as the wheel starts turning. Gets worse when I turn left almost disappears when I turn right. Gets really loud if I hit 70 MPH. Took a friend's advice and replaced the CV for the front passenger side and it made no difference whatsoever. Whatever the problem is I think it's tearing up the motor mount too.

Hi,

The idea that it nearly goes away when you turn right and is worse when turning left indicates it is likely a wheel bearing. What happens is this. When you turn, you shift the vehicle's weight more to one side. In this case, when you turn left, you are placing more of a load on the right front wheel bearing. When you turn right, you shift the weight to the left. Since it is nearly gone when you turn right, I suspect it is the right front bearing.

Please keep in mind, it could be a brake issue. However, you should hear a change in the sound when you apply the brakes. If that doesn't happen, then suspect the bearing.

Here are directions for the replacement of the hub bearing. It comes as a unit and bolts to the steering knuckle. The attached pictures correlate with the directions.

1. Install the wheel bearing/hub with the splash shield as noted during removal.

Caution: These fasteners must be replaced with new fasteners anytime they become loose or are removed. Failure to replace these fasteners after they become loose or are removed may cause loss of vehicle control and personal injury.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install NEW wheel bearing/hub bolts.

Tighten
Tighten the NEW wheel bearing/hub bolts to 130 Nm (96 lbft).

3. Install the brake rotor and caliper. Refer to Front Brake Rotor Replacement See: Brake Rotor/Disc > Procedures.
4. Install the front wheel drive shaft nut. Insert a drift on a flat-bladed tool into caliper and rotor to prevent the rotor from turning.

Tighten
Tighten the front wheel drive shaft nut to 160 Nm (118 lbft).

Here's a video of me driving to work last night. I don't get over 40. But as I mentioned it gets much louder at 70 exactly.

Hi,

I listened to the video. Please keep in mind, there is a certain level of quality lost by any recording, but from what I can tell, it is a wheel bearing. If the sound goes away when turning right, I would replace the right front wheel bearing.

I attached the directions above. If I can help or if you have other questions, please feel free to let me know. Also, let me know if that takes care of the problem.

Take care,
Joe
