Hopefully someone can sell me a set if not i would have to go with fastlane but i still want to know if i should change them both and also if i should go with rebuilt or new thanks guys

Giggle giggle... We know what you meant! Max, I would make dang sure the axle is what you need before I threw two of them on it. Have someone sit in the back seat with the windows down. Take the car into a parking lot and make several left/right sharp turns from standing start. Have the listener listen out both windows and determine which side is the loudest. Replace that side if you are convinced it is an axle. If it continues to pop replace the other one. But, consider this. This is one of those situations where a good tech would be valuable. He might save you a bunch of money!

Oh well the funny thing is I jacked up the car and the axle boots looks fine off course that doesnt mean they are in good working condition but .Any ways i did what u told me and i could not tell where the sound was coming from sounds the same both side BUT it only does it when i am taking a right turn. I just hope it is not the rear end that s gone

sounds like a rear wheel bearing is gone. What kind of sound is it?

If it goes away when you turn one direction, then that is most like a bearing.

I just had my left rear done. the sound would go away when making a right turn.

Have the wheel bearings checked first. if the axel boots are ok, then most likely the axels are fine.

I too thought it might be my diff, but my mech and I investigated it and I described to him what was happening, and had him drive the car. After replacing the bearing, the car is quiet as can be.

Do not just start replacing things. I would look into a mech that can properly diagnose your problem.

If the sound is a constant grinding type noise at any speed that gets louder but stops when you turn right or left, its most likely a bearing.

Have the bearings checked first. my left rear bearing was still in tact but it was grinding on itself.

thanks guys for replying to my post
well everytime i make a right turn the rear axles or bearing dont know which one yet start making the noise then after i speed up to about 30 mph the sound is gone and also when i go to a complete stop when i take off the car would make the sound only for a short time.
