Hi Jyad :-)

It is either your rear bushings that need replacing or, as you say, some space in the gears in the differential. It is very common in older diff's and is not so bad, it is just annoying.
I have the same problem with mine but have learned my self to drive so it can't be heard or felt.
The only way to solve the "problem" is to change the gears in the diff or the intire diff. I donīt find it necessary on mine because it is quite expensive and the gain of fixing it is small...
