Yesterday I changed my pinion seal as I saw oil coming from there. I took it out cleaned it up and added more oil, today I crawl under to take a look and I still see oil seeping out.

Is there anything else in there that would cause me to have continue to have a leak?

Thanks,
Jon

check your vent line, if it is plugged it is causing the pressure to build i nthe diff which blows out seals

The only place where I could see a hose going to the differential is here:



Obviously there is no hose plugging that hole, but there is a cut hose leading no where underneath:


Am I even in the right direction on this lol?

that is your vent hole lol. that needs to be replaced cause crap will get in there and the grit will ruin your diff

So I just need to replace the hose, so no crap gets in there and hopefully I will get my seal to actually work?

as far as your seal goes... was it installed dry or wet (wet with oil)

Can you move the pinion flange (up,down, L,R)? If so the pinion bearings are trashed. What did you torque the pinion lock nut to? There should be a hose and not a hole btw.

I used a tad bit of oil around the edge of the seal. Maybe I didn't put enough on?

I torqued it to a little bit over 200.

next thing is movement? that is a good point about pinion play

Skyline

I didn't check the flange when it was all apart. I can move the Driveshaft a little bit though. no forwards backwards but up down left and right.

the does the pinion move when you move the DS? the DS has a bit of play due to the slip in it

Skyline

si? I am not sure I know what you mean.

96_xj

fixed. i dont know what happened

Skyline

I think so, I can see the seal around it moving when I move the DS, I can't actually see it but it looks like it is moving.

I am going to take a wild guess that the pinion bearings have gone bad.

X2 wanna replace em before something binds up and breaks.
