Need help with Axle leak!!!

Hello everyone,
I have a problem in the rear... (lol)
My axle hose, what some of the people called it on here, is leaking really bad all over my garage floor, and it gets on my nerves. Idk what to do...
I know it's a D35 with 35" tires, and that is probably the reason. I want to know if that is sure the reason. When i'm on the highway i'm fine going 60 mph on FLAT ground, but once I hit a slope on the highway, it's all over, I go really slow, maybe 10-15 mph SLOWER! and then next thing you know zoom zoom zoom cars passing me, is the problem my axles?? please help me out! I have pictures of the hose leaking also!!

as long as thats your vent hose i'd make sure its not clogged, and how full is the diff? i can't believe its doing that and the pinion or axle seals aren't leaking? maybe its over full?

oh, and you need to regear to solve your hiway problem, but i wouldn't regear the d35 w/ 35" tires, you need a better axle.

pull the fill plug, and have a pan under it to catch any fluid that comes out. is your pinion angle changed to fit those tires?

normally w/ the stock pinion angle the fill line is to the bottom of the fill hole. so you fill it till it comes out the hole, then its full. but people tend to jam more fluid in there and plug it right away over filling it and causing leaks.

if your pinion angle has changed i'd do the same thing but jack the rear axle up a foot or so to level it out a little.

just an educated assumption here...

yea i think maybe that differential breather hose got clogged and built up pressure inside the axle. which eventually created like a volcano effect and errupted with gear oil out of the hose. the beather hose is meant to release this air pressure. i actually just checked my axles the other day for this. i took some compressed air to the hose and paper clip cleaned the base of the opening on the housing.. not to disregard the idea of an overfill though, that could hav also been the culprit. if not both.

If your vent hose is still in the stock spot as it looks like then I'd think over fill would be what is causing it to be slung out the hose. If there is too much fluid in the tubes the shafts will sling it everywhere including out of the hose.

So does anyone have like a DIY walk through on how to do this? With pictures, or even a video?? Would be great thanks. Another question is how do I clean like the black sticky stuff off the frame and axles? Wire brush??

Remove the fill plug on the axle. If any runs out then it's too full. Depending on when you last changed your diff fluid it would probably just be a good idea to pop the cover, drain it, reseal and fill with appropriate amount of new fluid.

Is there anywhere, like a website or something, that will show me how to do that?

put a drain pan down, remove the bolts that hold the cover on, leave the top bolt in but loose so the whole cover doesn't come flying off. tap with a hammer, pry with a screw driver and all the fluid comes out.

clean it all up, scrape the silicone off the surfaces. apply a thin bead of rtv silicone to the cover and put it back on and tighten it up.

fill the fluid.

I did have similar problem but I solve it as per advice from this forum, just open the differential plug with a drain pan under, and after a few hours put the plug again and problem solved, it was overfilled now is fine a differetial cover is clean all times.
Below find a link for change the oil hope it can help. Luck
