Spotted a leak on the Ranger.. I need some input guys!
 

Hey..

I noticed a few small drops on fluid on the ground underneath my Ranger this morning. I got underneath it and found it was coming from the front passanger side right where the CV Half Shaft meets the Axle/Differential. It appears to be gear oil. I had the truck geared at Randy's Ring and Pinion about a year ago and they also swapped in some brand new half shafts. Since then, have had it in 4 wheel drive just a few times through this winter. Does anybody know what this could be? What might be causing this like a seal or something. I wiped all the fluid off, and am going to continue to keep and eye on it. Any help would be appreciated.

Thanks!
