Team, I have a question? I have what I thought was a minor rear diff seal leak! So, I start to top off, and used 1 qt of fluid. Is this bad news? I am scheduled to have this seal repaired next Thursday. The rear diff did not appear to be that wet. Any opinions are welcomed.

 

It could have been there for a long time and you didnt notice it. Just top it off. Youll be fine but I would check it every few days so you know just how bad it is and if its low again just fill it up until you can get it changed

 

you did fill it at the plug on the driver side of the diff ?

a quart is about 1/3 of the total capacity of diff, I would be real surprised that the diff wasn't wet

 

Check the vent tube and make sure it is not blocked or pinched.

I've been there and done that with a pinion seal leak. Just keep it full from now on and don't worry about it. It got a little low and there's nothing you can do about it now. I would bet good money you won't have any further problems. I didn't.

 

This is to keep it from pressurizing correct?

 

Yes simple but affective

 

So...Team, you think that some over heating damage may have occured In the rear diff?

 

I went on a 300 mile trip pulling a heavy trailer at hyway speeds, went I got home and was updocking the trailer, saw spots of oil on my bumper, then noticed how wet the bottom of the diff was.

 

Sounds like the vent tube is blocked. Take it off blow thur it and replace. The clamp that held mine on was pinching the tube closed.
