Power steering leak

Was cleaning up the engine bay and noticed this bulge grime. What is my Likely culprit?

I hit it with some degreaser but I was wondering if this area is common for leaks ?

 

Usually there’s a common leak from the boot. Yours appears to be from the coupler.

I’d clean it up to see exactly where it’s originating.

Edit: Now that I'm seeing this on my computer instead of my phone, I don't know what to make of it...Is that just rust on the coupler or is there residual fluid?

 

Yea eventually they leak. I just had my steering rack replaced. Upgraded bunch of suspension parts with that

 

What is the coupler. Sorry. Just getting into this steering stuff. Circle that bad boy
I just hit it with degreaser so I’ll report back on the update.
If it is the coupler ? What is the fix. A new rack ?
Mine is orginal. 2000 /244k

 

Maybe not the coupler itself where the intermediate shaft joins, but the lines underneath the coupler could be leaking I suppose. Just clean up that area if it’s coated in fluid.



The coupler is above that.

 

It never dripped on the ground. I did have the poly bushings put on the rack a while back. I guess it’s possible the pulled this off and this is residual mess. I will report back with pictures if I find it be a problem.
