1977 450SL steering box
 

Ok... I think I know the answer here, but am hoping I will be pleasantly surprised.
The box is completely dry and working fine, except for a substantial leak at the steering shaft seal on top. No excessive play or any issues, just the leak at the top.
I have my full seal kit here on the branch, ready to go. The top bearing cap and all that came off very nicely. Now.... The big question:
Do I just do the bearing cap o-ring and input seal, or do I tackle the whole reseal job? Is it coming out of the top because of excessive pressure below, or should doing just the top seal fix it?
I know you are all going to say: you have it out already, do it all! But I really don't have time. Sure would be nice to press this seal in and be done.

Sorry do it all - it will save time in the long run.

It will also make sure all the gunk in there is removed.

Here's some help =>

I'm in the process of selling it... Does that make a difference in the answer? Haha...

Well you should have used magic goo and then I'd post up the link for the new frustrated owner!

Haha! Yeah you're right. I don't want to be that guy.
