Hello all. I’ve read a number of posts on leaking front diff housings. I’ve got a ‘94 factory triple locked with just shy of 408,000 miles. I’ve confirmed torque is good on all of the bolts.
After parking I get a few drops over several hours from the bottom of the front diff housing which will form a 2” diameter mark on concrete. It will then stop until the vehicle is driven again. This leads me to believe the origin is above the standing level of the fluid. After cleaning and observing, the leak seems to come from the top area of the lock actuator, about 2 o’clock when looking from rear towards front of car. I can’t tell if it’s a bad diff cover gasket right in that area or if it is simply leaking at the actuator interface.
I’m hoping there is a chance it is just the seal between the actuator and housing.....
I‘m currently awaiting the front actuator rebuild kit from Wits’ End. The actuator works ok and I’m debating whether I want to open it up for a rebuild or just pull it and replace the o ring at the interface. I suppose when I get it off I may get more insight into where the leak is originating.
Can a failed seal on the actuator cause leaking diff fluid?? Anyone have success just changing the interface seal?
If that seal is in similar condition to other rubber seals on this rig (oils level sender, distributor o ring, etc) I imagine it could be a simple fix. I want to avoid having to pull the third member until I’m ready to do a complete brif rebuild and there are no indications that is currently in my immediate future.
Thanks
