help! steering rack replacement troubles

hi! so i just installed a brand new rack and pinion that i bought from detroit axle. everything went super smoothly until… just now when i turned her on and started steering left to right to get the new ATF flowin there is a leak. on the BRAND NEW steering rack. it seems to be coming from the input shaft right on that first seem below the intermediate shaft. has anyone else had this problem? am i missing something? is the new rack and pinion bad? wtf should i do?

much appreciated

Are you sure that thing is bran(d) new? Or Is it a reman? Sure looks dirty with weird paint chipping and bubbles. Definitely looks like a bad seal on that shaft. Either way, Detroit Axle offers a warranty. PITA, I know, but it's no good this way.

 

This is the state of aftermarket parts these days ...

 

Ooooo…I haven’t seen a new coupler in a long time. Mine is just a hideous ball of rust.

Wish I could help on the leak though.
