Default axle seal or no? (4x4) Pics...

ok so ive noticed a slow leak on the front axle passenger side...

does anybody know if this is an axle seal? or something else? cause it kinda looks like the axle seal would be where it goes in closer to differential...

this leak is coming from the block area...

heres some pics...

Yes you have to open the diff cover, take off the cross pin and the C-clip and spiders. Then remove the axle shaft after you remove the CV axle. You can check the FAQ for the service manual.

yep axle seal. easy fix heres how

unbolt the big axle nut while the truck is still on the ground
remove the 6 14mm nuts holding the axle to the flange at the diff
remove the diff cover
unbolt 8mm bolt holding the center pin in place
MAKE SURE YOU DONT BREAK IT OR YOUR GOING TO HAVE ONE HELL OF A TIME
make sure its not going to fall into the diff housing itself, its a pain to get in and out if you do.
push said axle toward the center of the truck, the C clip will fall out.
remove C clip
axle should be able to come out now, pull back and wiggle it out.
use a seal puller to remove seal,

install is reverse of removal.

And don't forget to replace that oil pan gasket I see leaking in the background.

The only thing I would change about this procedure is there is no need to remove the cv axle nut at the hub if you aren't pulling the cv axle all the way out. I've never removed it any of the times I've unbolted the cv axle from the flange. Otherwise, you pretty much got it!

That looks more to me like a leaking rear main seal than a leaking oil pan gasket, but either way, good spot! Hard to say which without looking closer at it! But you may want to go ahead and remove the entire front axle housing and pull the oil pan out and fix both at the same time.

um i have a question. that looks like the passenger side of the front axle. why is there no automatic locking hub setup on it? there should be a plate attached with vacuum lines and a fork to connect the outer axle with the intermediate axle. is that just on the 87-91?

93 was the last year of the CAD Central Axle Disconnect. Not locking hubs. But I'm assuming the OP is about a 93 so it should. Maybe it replaced with a newer axle at one point.
