I was trying to back out of my yard and something popped underneath my truck. now in reverse all i hear is a high pitched whine and the wheels will not spin. in drive yes but not reverse.

Do you hear it with the vehicle sitting still? If so, what about serpentine belt or belt driven component? If you only hear it going down the road, check wheel bearings and such. My hearing is no good, I can't diagnose with noise/whine? Just my opinion.

It sounds like a Bearing is worn in one of the wheels or in the Drive-shaft. Get a mechanic to check it out

A high pitched whine like that indicates a bad bearing. Water pump, power steering pump, accessory belt slipping, alternator bearing, or in the worst case scenerio, Transmission pump.

Transmission pump.

It is a wheel bearing, no doubt.
the wheel bearing is pressed in so if you do the job yourself you will need to take the hub somewhere to have the new bearing pressed in, but 100% the bearing.

The most common cause would be a defective power steering pump.

Hi Charotte,your engine is not a interference engine.So your in good shape.

Whining high pitched sound from front end...left front wheel bearing or right it could be hope this helps tell me if it does

The high pitched whine in reverse sounds normal for a honda. Ever honda I have had makes a similar noise while in reverse. The spinning, scraping noise in drive is not normal. You might want to see a mechanic about that.

hat u need to do is drive vehicle until you hear this pitch once you hear it turn steering to the right to see if whine disappears if it does you are looking at replacing wheel bearing.
