Hey everyone, I've noticed that when I jack up my car, at least from the front, that I will end up getting some weeping/leaking coming from where the slip yoke meets the transmission seal even after I put it back down on the ground. It seems to stop eventually, but it's going on for nearly a day this time. I'm not sure if the slip yoke is sticking out too far or anything either, but it's a summit aluminum driveshaft P/N SUM-790303 (came with the yoke attached) and a tko 600 in an 82 mustang with a 351w swap. I'm wondering if I need a new seal, but then again I'm wondering if the yoke should be slid in further, which i'm not sure if that's even possible.

Does the car have weight on the wheels in the picture?

I’ve encountered a little fluid weeping past the rear seal before, but as long as it’s not dripping on the ground I wouldn’t worry about it.

The weight is on the wheels in the pic, I jacked it up yesterday for like 30-45 mins, put it back down and noticed a little while later it was dripping. Continued to drip until this morning, a total of probably 2-3 tablespoons worth. But it has since stopped

Looks like the stick out is a little over an inch? Might be out a little more than you need, but I wouldn’t worry too much.

I’ve seen the drain and fill plugs on transmissions leak when people don’t put some sort of sealant on them as well.
