Rear diff oil in wheel hub! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Nima** · 03-24-2006, 03:53 PM

Hi guys/gals:
Well, I was getting ready to do front disc/front end upgrade. I also wanted to freshen up my rear brakes since I don't think anybody touch them for long long time. Anywasy, when I took my right rear wheel out, rear diff oil poured out from wheel hub. What does that mean?Is there any seal or something?
Thanks.

Yep, you're seal needs replaced...and so do your shoes now too.

Thanks Longhorn man. What does these seals called? Are they easily available?

Rear axle seals. Auto part stores usally have them. Careful putting them in..I use a wood block with a hammer to install.

I don't remember if there were any issues when i replaced mine last year, I know I had LOTS of issues getting brake parts, but the seals were pretty easy if I remember right.
I used NAPA, and honestly, wouldn't trust anyone else (as far as parts stores...not talkin resto vendors here) with parts this difficult.

Is it difficult to pull out the seals?

If you pulled out the axle shaft and gear oil came out, that is normal. On a full floating axle, the wheel bearings are lubed by the gear oil.

Oh boy!, I think I am gona need help with this seal thing. Longhorn man, about the brake parts, I see that most auto part carry them on their web site at least. Is there any specific part/parts which I am gona have problem finding it?

If he's talking about the C-20 in his sig, I bet that is what happened

Well, mine is a one ton, HO72 instead of the HO52... EVERYTHING was hard to find on mine.
If your truck is a driver, be sure everything is right before you disable it.

Yeah, what exactly did you mean when you said, "I took my right rear wheel out?"

And, did any gear oil get on the brake shoes?
