Please help!

My 92 500E has play in the stering box and it seems like it is only when the car is slightly turned. It seems to be tight when straight forward. I noticed this due to inside tire wear. I also have leakage from the input shaft but am double checking that now.

I need to know why this is happening and if there is anything other than a new box to fix it. If it is too expensive I will be selling the car as i have a new toy in the garage and this one is not driven much anymore
