My front transfer case that is attached to the front drive shaft and then into the front axle is leaking. Could this be a bad seal somewhere?

The truck has a little over 105K on it. And I have never changed the transfer case oil or rear axle oil either..... Would that be suggested at this time in my truck's age?

 

I am having the same problem. I am 99% sure its the front pinion seal.

I dont think they are to hard to replace. I would love someone to post a write up.

 

^ yeah I am thinking the same thing. No joke, I would love for somebody to do that. It might be us! haha

It really wasn't noticeable at all until I changed oil in the truck a week ago. I was like holy crap, where did all this oil come from all over the transfer case lol.

I just hope I haven't messed anything up, b/c I have been running the four-wheel drive a lot here lately b/c of the winter and hunting seasons.

I'll check on the front pinion seal tomorrow at the mechanic that I always use and see what he says after he checks it out.

 

Did you just change the engine oil?

Since you mention that it wasnt a problem until then make you didnt tighten your oil filter enough and its leaking? Just a thought...

 

Yeah man I changed the engine oil and filter. I have been wrenching the whiz out of the filter and drain plug and checking for leaks out of them. It is def not them. I can actually see the oil coming out of the front transfer case sometimes.

 

The front pinion seal is super easy to replace.


1. Unbolt driveshaft from yoke
2. Remove pinion nut with impact.
3. Pull the yoke off
4. Pry pinion seal out
5. Press new seal in
6. Push yoke back on
7. Impact pinion nut back on
8. Bolt driveshaft up.

Seriously this is a common thing on Rangers and it shouldn't take more than an hour to do. A new seal is around $10.

 

Haha cool, thanks!

Any brand you would consider over others?

 

Nope. I just bought the cheapest one from the local O'reilly's and never had any more problems with it.

 

Coolbeans man. Thanks!

 

Took it down to the shop today. Ryan, you were right. My front pinion seal is just worn out. I guess I know what my Saturday morning looks like lol.

Thanks again for the help.
