a shock question

when the factory shocks kick the bucket how much will they leak? I seem to be getting a lot of oil around the rear passenger side of the truck where the shock is. I know that my t-case leaks but I checked it and it hasnt lost hardly any since i topped it up last and the rear diff is full. stock rust proofing is nice but it makes me wonder sometimes.


I should put my OME suspension on but I hate to upset anything that hasnt shown up yet.

Follow-up Post:

a few photos, my rear pinion has always been "wet" but I keep it full and only have to add about every 3rd oil change.

Are you sure it isn't coming from the axle seal? It is hard to see in the pics, but usally if the axle seal goes the lower part of the dust shield will be covered and the entire inside of the wheel is usually coated. I can't see if that is what yours looks like or not, but take a look at that seal.

I was thinking that but I have recently had the wheel bearings done so I assumed that would be okay. Plus I havent had to add oil to the rear diff for quite a while. I have noticed a wet spot around the axle breather recently and the pinion has always always been "wet" so much to do so little time.

It just seems odd, usually if it is a shock it will leak from the seal where the shaft enters the tube, but it just seems to be around the bottom of it. You don't have a brake leak at that wheel do you? The pictures just seem to show a very strange pattern/placement of oil. It is all over that lower shock mount, but it is also on the backing plate a little and all over the inside of the tire, so it is kind of hard to tell.

That seems like a lot of oil to be from the shock...

I know my transfer case leaks especially when its been at highway speeds for a few hours. I will check it but I am pretty sure it wont need any. my shocks are pretty cashed and I havent seen oil on the lower shock mount before, I have seen it down the right rear of the truck in the past. The brake fluid is at the max line, I had to top it off a couple years ago when I first got the truck because the light was blinking.

last pic says rear pinion>how does the other side look??
That would be my guess but the I think first looks like bearing. but it doesn't look like that cuz the wheel would be a mess.
I still say pinion

Smell it. Shock oil does not smell like gear oil. I dont think a pinion seal leak is going to collect on the lower shock bushing. Its either gear oil leaking through the hub seal or shock oil. JP

Jp you have a good point about smell.[taste works well too] but fluids don't go forward? & the pinion housing is soaked & there are slatter marks??? If the other side is dry then pull the wheel & have a look around the bearing. You could extend the shock more & see if its dry there.
A web diagnose is pretty hard.

its definatly gear oil. I think its must be the axle seal. How hard is it to replace? full floating axles it doesnt seem like it should be to hard to repair.

has always been "wet" every time i check the level in the pinion its always full. I just got done with a road trip and the passenger side rear is covered with gear oil, all over the mud shield inside of the tire, it was dripping off the lower shock mount, it looks like it does in the photo above. I think I just need to go find some mud.

Piece of cake. Just remove the wheel, Caliper and rotor and unbolt the flange from the back. The axle will slide right out and just use a puller the pop the seal out.
