A rare sound after changing shock absorbers

Hi, I wanted to see if someone can help me on the subject, a week ago we changed front shock absorbers to my car a Mazda 323 year 96, but it turns out that after having changed them sounds a rather ugly noise is like a buzz that comes from the right side of the car, tube the opportunity to try it with a friend but told me that perhaps it was the dough bearing ... but that now the noise comes from the box ... Disassemble the box? Someone has happened to someone with his car, I just want to know what the problem can be since the more slow it sounds and in the curve the right side vibrates .... I await your advice ..

First you must change the bearing that your friend told you, after this check the oil level of the box.
If the noise is still carefully checking that component makes the noise, since it can be confusing, between the box and the wheel there are elements that can cause noise (1. Double dump or dough beal as they told you, 2.Spiga, 3. Tripoid

What is such, usually happens that when changing shock absorbers can accidentally dislocate homcinetic arrow shots (CV joint axis) check this and bamboleo of this part when working or check dough dough to avoid overlooking that something is damaged

It can be a beel, or a tripode; It is very easy to know if your bearing is that of the problem and determine what it is, you can listen to the noise on the right side, but it may really be the one that is damaged is the opposite side; To determine it you will have to do the following:

1.- Raise the car with the cat, until the tire to be checked is free, turn with your hand the tire and listen to the sound it generates when turning. So with each one.

If you identify the sound you hear, eh the problem, if not perceptible, touch the main wheel or support for the wheel you check and could determine with the vibration if your wheel is damaged or not.
