Differential yoke leaking....

Differential yoke leaking....
I have a spraying effect on the underside of my car in the area of where the driveshaft connects to the yoke.
Where the seal is located at the differential and the yoke penetrates the housing is bone dry.
Is there an o-ring or another seal in this area?
Does anyone have or or has anyone seen this issue? Repair suggestions?
Thanks in advance!

I have not done anything at the moment. I have been trying to locate a Quafie rear for it. Actually another housing and rebuild it with Quafie assembly, seals etc and do an entire diff changeout.
It does not drip onto the garage floor. I did have the fluid changed out which was really dark. I have an BMW/Mercedes independent mechanic about 2 miles from house really sharp and v reasonable. I’d have him do it. We already discussed. I’m getting to old to work without a lift.
I spkoe to the Jag dealer here and they said $425-500 to fix the leak. If it’s not dipping I’m leaving it until I get another diff.

I tend to agree that no drip is no leak but still want to be ready for the drip which will probably follow...
I think I will buy the pinion seal and new fluid and take care of them both once I'm in there.
Not sure if the shaft need to be completely removed for changing the seal or just remove the rubber doughnut ?
BTW what fluid for the 4.2L N/A ?

DannyJ, you are leaking around the nut that holds the yoke onto the pinion shaft. The '03 and up Lincoln LS diff is a direct swap and you can get 3.31 or 3.58 gears. I went with the gears and haven't felt the need for a posi unit yet. I have pics in my build thread of the swap. Overall not a hateful process.

Can you send / post the link to your direct swap to the Lincoln Limited Slip diff.
Danny as Ranchero stated per the pics it’s NOT you yoke shaft seal (pinion). As for fluid I used 75/140 full synthetic.

I did read you thread anyway. Great info and writing
If the leak is from the nut area will it be enough to remove the yoke and put some RTV on the pinion or is it the oil seal behind the yoke which should be changed anyway ?

I want to say there's a molded O ring into the nut's face to seal the pinion spline to yoke fit. I think I have the spare floating around and will check it when I get home.
