I just replaced the passenger side front bearings and the cv shaft cause of a whooping noise. However, the whooping sound is still there but it starts to go away when you drive and turn the car to the right. Any help would be great.

OK so it's your CV axle most likely during slow revolutions it clacks and makes noises so replace both sides to ensure transmission/engine performance stays optimal to power applied to the road. The other cause of noises in that area are due to the wheel bearings needing replaced usually and sometimes repacking the bearings instead. On your car if the axle passes through the wheel it has to ride on something to control balance and torque across the drive shaft. I would replace both front driver and passenger side wheel bearings and the CV axles on both sides please be smart people and replace parts like these in pairs/ together the reason being after you replace one side you drive a few months or less and the other side goes out almost always soon after the other I would say over 75% of the time let it be bearings/u-joints/CV axles or other crucial parts. Hope this helps please take my word and fix it right the first time and please buy the better parts not the cheapest parts out there if you want quality/ safety than buy the better or best parts never just the good or OK parts

Cv axle assembly inner and outer constant velocity joint

jack up front left on level ground ,support and chock rear wheels and set park brake ---look and check the cv axle for leaks,tears or damage -put in neutral and watch axle should turn smoothly turn steering wheel to left and rotate tire again watching axle if their is binding or grinding or studder movement than axle is damaged and needs to be replaced

do u have a smooth transfer of gears in your ******? my explorer sounds like it only at about 30 to 40 mph. could be your hub bearing assembly on the rear...but if it is that, then usually it will be louder as the car goes faster.

Have you checked the front wheel bearings? I've seen similar problems on several front wheel drive cars. On my first experience, we also started by changing the CV joints only to find it did not solve the problem. We then though it was a transmission problem.... wrong again. Finally checked the front wheel bearings (Both sides) and found the passenger side was making the noise. Bearing replaced (not cheap by the way) but solved the problem.

Most likely cause of loud popping noise would be a broken or breaking cv shaft. The cv drive shafts have a rubber boot around the bearings on the shaft. Look for a broken rubber boot on the shaft that runs from the transmission housing to the wheel hub area of front wheel. If you find a broken or cracked boot then most likley the **** needs to be replaced to solve your problem.

sounds like front wheel bearings. does the noise change, get loader when making turns?

One of your CV joints are bad, inspect which CV joint needs to be replaced. Roll your windows down and make tight right and left corners in an empty parking lot slowly and listen for the clicking noise. If it's coming from the passenger side window or the drivers side window, which ever side the noise is coming from is the side that the CV joint has failed and will need to be replaced.
Thank you for using FIxya and replacing the front wheel bearing improperly buy hammering the CV joint out instead of using a wheel bearing puller will cause damage to the CV joint as to what you have described. Good luck and keep us posted.

You may have pulled the inner tri-pod joint out of the cv shaft and that will make noise. Is the bearing really bad? Does it turn freely?

I am assuming this is an all wheel drive. That being the case you probably have an axle CV joint going out. If you hear noise when making a sharp left or right turn and accelerating that would more than likely be the problem. And, yes this is a serviceable part. Easy to replace if you have the proper tools to accomplish the task. Good luck.
