I am quite sure that the rear leak is the rear wheel seal. The pinion seal in the rear was leaking, as well as the front pinion seal, but I am quite confident that they stopped, and it was only due to the universals being bad and causing a chatter.

This weekend I am planning on doing the rear wheel seals, I might as well do both of them if I'm getting into this, as well as the rear brakes since they are in dire need of replacement (55k miles).

Should I replace anything else in the rear differental since I already will have it open?

When I say the rear wheel seal, I am talking the furthest out one that is infrotn of the wheel bearings.

In addition to this, when I was looking under my truck... I caught a oily glimmer from the sun front the front axle :(

I included multiple pictures since I just cannot get a great one since its so tight under there and its on a gravel driveway.

The pictures are of the front passanger side portion of the axle. I believe it is leaking before the CV boot? This is something I am clueless about, so I included pictures. The oily substance seems some what thick, but more caked on. Now it has been in recently for service and nothing was mentioned about this. The fluid has the consistancy of motor oil, but maybe a bit thicker... like a SAE 30 or 50

Please if anyone can give me some insight on what may be causing these problems, I would be open ears.

Also should I change the wheel bearings in the rear since I will be doing the seals and brakes so they are all done? is there a inner and outter seal? If there is a inner one, should this be replaced as well?

I am going to be using this truck as a company work truck, and it has to be reliable and cannot be breaking down... it will be towing every day.

That is to my photobucket slideshow. There are alot of pictures of this, I do not want to bog down the server. If you guys want I will post them on here though. They are bad pictures since the trucks in a gravel driveway and im just a bit too bit to twist around under there.

 

My guess is wheel cylinder for the top pic. How are your brakes feeling?

 

Looks like you may need a need a side seal on the front axle. You have to get the drive axle out to change it. Clean it up and drive around. Look to see where its coming from.

The rear does look like an leaky wheel cylinder. Take the drum off and have a look.

 

I was told that at my last service that the wheel seal was leaking, I have yet to pull teh drum off, but i'm going to bank on that it really is bad.

My brakes go to the floor almost, like my brakes are severly worn. I know the front ones were done 5k miles ago since I did them myself. I suppose I will have to look at them tomorrow.


To change this seal, is there any good resources?

 

axle seals..

 

If your pedal is going to the floor you have a bad wheel cylinder from the pics! Make sure you keep an eye on your brake fluid reservoir. Also you should check the seals too.

 

I am more worried about the front one, since that looks like its been going for quite a while.... I'm curious how no ones noticed that... there is caked on grease and oil everywhere....

 

X2 it could be a wheel cylinder in the back, but id bet its axle seals. def axle seals up front. ive replaced all of those on mine

 

How would I go about replacing the axel seals up front?

The rear is the axel seal, I looked at it today... and the brake shoes haha they are about gone.
