RT4WD - Play in the rear driveshaft. Major Leak.

Well, this past Wednesday I was driving the wagon like I normally do and I started to hear the transmission make a slight whine. Kinda like when you go in reverse. I was lucky to pull into a friends apt complex and parked the car. I look under the car and I see transmission fluid steadily pouring out from the lower metal plate cover.
Immediately I thought it was just a CV Shaft seal on either the driver side or passenger side. We jack up the car and find that the rear transfer seal is leaking and there is play between the transfer case and driveshaft. I can move it up and down and side to side and in and out. Not much, but the play is there. Enough to make noise.
I checked the manual and all it says is if there is sign of leakage to replace the seal. Doesn't mention anything about play.
I wanted to ask if anyone here has had any experience with this particular issue regarding the 4WD system.
If anyone has any input I would greatly appreciate it. I am in a real pinch because my CRX is also down for the count so I am stuck like chuck til I get one of them fixed.
Thanks Fellas!

So far these are the parts I assume need replacing. Anything else?
#22 91201-P1D-005 OIL SEAL (38X60X11)
#20 91123-PS5-013 BEARING, TAPER (28X58X20) 320/28x bearing part number
#09 29352-PH8-910 WASHER, RR. TRANSFER
#19 91122-PS5-003 BEARING, TAPER (35X62X21)
#23 91303-PH8-010 O-Ring
22. Oil seal. 91201-P1D-005
19. Bearing. 91122-PS5-003
20. Bearing. 91123-PS5-013
23. O-ring. Yours may be fine, but it's cheap and easy to replace. 91303-PH8-010
#8 looks like a crush sleeve, so you'd need one of those, but I don't remember exactly. Before you order parts I would take apart what you've got to check for damage.
I may have missed a part so double check...
I will. I've been spending time looking up parts for the CRV transfer case and parts to see if there are things that can mix and match. Found maybe 2-3 parts tops. The rest is totally different.
Just hoping there isn't any damage to the gears. I'd hate to lose the 4WD. Not so much because of it's use, but because I hate fakin' the funk
I know this may come across as a dumb question, but where would I take the driveshaft to see if it's balanced and straight? Is there a specific shop type?
I'm sure there's more than one local to you.
I found a replacement transmission on ebay and I wanna say it's a hydro transmission but can't tell for sure.
What would I need to make this work?
If the rear transfer case and gears are damaged beyond repair I may just pick up this one and use it as a donor tranny. Still comes out cheaper than buying new parts from honda. Just pricing stuff ahead of time if my situation turns for the worse.
bull shit. dont talk about what you do not know. YOU CAN NOT REMOVE THE TRANSFER CASE WITHOUT PULLING THE TRANSMISSION. anyone that says this is a damn liar. i want video proof of anyone who says they can do it. video fucking proof.
And now to address your issue. I'm willing to guess that you're transfer case ring and pinion gear are trashed. When mine started making noise it was trying to eat its way out the side....see photos below.
was it leaking out of this end?
if so, then you are looking at having to replace parts like these....
^^^see the rubber O ring^^^
let me know if you have anymore questions....i dont think you need to re build your transmission at all....
Yes, that's exactly where it was leaking from. Right where that round metal cup is at behind the square. That whole part had some play. So I will more than likely have to remove the transmission eh?
I usually fear doing transmission work, but I don't wanna lose the 4wd.
PS. Thanks for the detailed pics and help on such short notice. I appreciate it.
rebuilding a transfer case is pretty easy to do. i picked up a bunch of parts from jaker when he was selling off his parts....i'd totally sell you off some of the replacement parts buttt.......i plan on wrecking mine so i will need all the spares i can get. Once you get it out, see if you can find a local bearing place in your area like i did and just take all the bearings down there and see what they can do. i'd post up a WTB and see if you can get your hands on a transfer case.
Well, I had planned on buying the whole bearing setup along with new seals and o-rings.. and even the gearset transfer bevel if I had to(#5 in the diagram). IF it's not available then I am gonna have to buy a donor transmission off ebay. I assume the hydro version of these transmissions are the same internally. God I wish CRV transmission parts were compatible
@grifty - i know the manual says...but i call epic bull shit haha. i tried once, my buddy tried, my other friend tried, and our master tech at work tried....it wasn't happening.
Thanks so much for all the diagrams and help. This is definitely gonna be something I archive.
This is what I found when I finally got my oil pan off:
Yes sir. However, I already had the oil pan completely loose and stuck on the transfer-case. At the time I didn't realize I needed to drop it to get the oil pan off. Perhaps that extra long bolt that stopped you was not as much of an issue since I had some wiggle room in my oil pan.
Finally got around to having the car checked out.
Transfer case successfully removed and the gears inside were perfect. From what I can see it looks like bad bearings and seals. Honda no longer makes the bearings but I was able to get a friend of mine to source them, and the seals are still available.
So he's gonna go ahead and rebuild the whole thing.
We also did a viscous coupler check and everything is fine. Ujoints are solid too.
