ID the leak

Went to pull the 90 out of the extra garage where is has been for 1.5 weeks and saw a huge puddle under it. Appears to be oil, but is dripping off of the brake drum. Did not have the time of clothes to spend much time under it...but could the rear main run down the frame/driveshaft this much when standing still, or is it a t-case leak? Also posted a pic of the fluid I wiped up and it smelt a bit t-caseish. The question is...what typically leaks and runs down to the brake drum?

if you are talking about the parking brake drum, it's is 90W oil from t-case. it's time for you to replace your rear output shaft seal. there is nothing else it could be from that spot. Unless you left a bottle of crisco oil in the backseat and it spilled. those are your options.

BTW, great writeup on replacing it on Dweb. No removal required. Did it myself in an afternoon.

Exactly what Mark said...had to do the same for mine, it was amazing how much it leaked. Get a new nyloc nut for it while you're at it, the parts I needed were:

(1) FRC7043 oil seal - transfer case output
(1) FRC2464 felt washer
(1) NY120041L nyloc nut

And I'm sure the brake shoes are soaked, but just use a whole can of brakleen to clean them up and you should be ok since it's just the parking brake (or if you want to play it safe get new shoes...I did not and it's been fine).

This is for front bearing, but includes seal. Front and rear are pretfy much the same.

If it has a sickening smell it's good old gold colored 90wt as suggested above.
Another clue is the gold color seen in the photo.
Used crankcase oil is generally black in color and mostly has more of a light smell of acid with a hint of burnt rubber (at least to my nose).

Hope this helps.

It was dripping off the parking brake. Thought is was too clean for engine oil and smelled like t-case fluid...looks like I have some work to do...

Been busy, so sent this to my mechanic...ended up being a loose nut and a crushed felt washer...super easy fix!

Had the parking brake pads replaced since they were toast and the t-case leak was cheap!

$230 with the brake pad replacement!

Parking brake pads were very expensive last I checked. Do you have some details over how much that piece of the puzzle costed you and where it came from?
