Leaking driveshaft?

[76cj7chick]

Hi jeeper people,

I was under my CJ7 and noticed what appears to be a leaking driveshaft rod. Could I get some feed back from the experts?


I researched leaking/broken driveshaft but haven't had much luck on the Internet. I do plan on seeing if the u joints have any play in them though.


Hope to hear from you soon

Thats just some grease; totally normal.

Are those metal shavings or something on there or paint dust?

Grease will seep out of the slip yoke as the suspension cycles. That is normal

There is a seal in there that can prevent most of the grease from coming out. BTW, that pinion angle looks like it is a little low.

some drive shafts are meant to leak grease out the splines like that. See where your grease fitting it? When you grease it the grease goes past the splines and leaks out there. That's how you know you have enough grease.
Some drive shafts have the grease fitting near the splines. Then when you grease it you expect the excess grease to come out a hole in the end of the drive shaft near the U-joint.

THANK YOU everyone for your replies! You've put my mind at ease!-- At least for now...:rock:

What is the "pinion" and is it bad if it's too low?? Do I need new u-joints, or?

It appears that your Transmission tailshaft angle , driveshaft angle , and rear axle pinion gear angle relationship is not correct, which should give you a vibration while traveling on the highway. Here is an explaination of what I am talking about:Tom Wood's Custom Drive Shafts - Driveline 101
It is pretty boring and hard to read but the pictures show what your driveline should look like with or without what is called a "CV" joint. I am just assuming that you are getting a vibration from your vehicle from adding high lift springs and not correctly coordinating the driveline together.

Hmm... I haven't driven much since I've been "rebuilding" it. (my first- and probably my last) As for the "high lift springs", one of the previous owners added that. (Let me add that both the Transmission (GM Turbo 400 ) and the Dana 20 "spicer" were out of a Full sized Jeep Truck (the last owner knew nothing about the Transmission . He didn't know it was a GM Turbo 400 either-- at least that is what he told me. So, perhaps the angle is caused from the fsj Transmission and Transfer Case , or not?

JEEP...Just Empty Every Pocket...
