ronin152 Posted July 28, 2008 Share Posted July 28, 2008 Talked to Alex about putting manual hubs on an all-mode 03 pathfinder. He said that the oil pump for the transfer case is driven off of the front drive shafts so it would not be a good thing to use manual hubs. Any one have any experience?

DTE Posted July 28, 2008 Share Posted July 28, 2008 That's news to me. Would be good to know tho. Link to comment Share on other sites More sharing options...
Jarsiff Posted July 28, 2008 Share Posted July 28, 2008 You cant use manual hubs on an all mode 4x4, screws with the sensors and throws the CEL if the thing about the oil pump is true also an even bigger reason why you cant do that. The manual hubs will only work on the manual 4x4. Link to comment Share on other sites More sharing options...
ronin152 Posted July 28, 2008 Author Share Posted July 28, 2008 Haha great...... I had planned on getting manual hubs to go with my AC lift I just purchased. The whole reason I got the AC lift is because I thought I could put on manual hubs to lessen the wear on CV's. This is great to find out. I confirmed it but looking at a parts description and there is indeed an oil pump in the transfer case? The stick shift trans case doesn't have one? Dammit nissan!

Jarsiff Posted July 28, 2008 Share Posted July 28, 2008 It definitely sucks that this info is going to hamper your plans, but its good to find out before you get so far into it that you cant go back or you find some damage. Link to comment Share on other sites More sharing options...
alexrex20 Posted July 28, 2008 Share Posted July 28, 2008 that is bad news indeed. does anyone know if the '00 model R50 also has a tcase pump driven by the front drive shafts? Link to comment Share on other sites More sharing options...
02silverpathy Posted July 28, 2008 Share Posted July 28, 2008 ~~~~~~~~~~~~~It all has to do with All-Mode...not manny or automatic transmission~~~~~~~~~~ If you can switch into 4WD with the lever than you can use manual hubs....if it is auto on the knob than you must keep the stock auto hubs. In QX$'s there was a combo for a while that had a knob and the lever at the same time...these folks were safe for hub AFAIK. Link to comment Share on other sites More sharing options...

My 98 has the knob for selecting 4x4 and the floor shifter for selecting low and I got errors. You can search for the thread under my username a few years ago. I still have the manual hubs but only to disconnect the front in case of breaking a shaft. Link to comment Share on other sites More sharing options...
ronin152 Posted July 28, 2008 Author Share Posted July 28, 2008 I read your thread. What ended up happening? Do we have anyone who has just a knob and has hubs? Does it work? It doesn't make sense to me though why you need a pump for the t-case? Doesn't the oil just slosh around and cool the gears? When I engage my 4x4 into 4hi I hear a low whirling noise from the transcase. I wonder if this is the electric pump working? I only hear it in 4x4. From the pictures I looked at it seemed as if the the oil pump was beteween the main drive gear and the front drive gear on the chain. But is CV wear that big of a deal if you have the AC lift? How soon will the cv's wear if you are a DD and do wheeling maybe 2-3 times a month that is moderate? Link to comment Share on other sites More sharing options...

You can search for the thread under my username a few years ago. I still have the manual hubs but only to disconnect the front in case of breaking a shaft. OOPs, I stand corrected! You were the QX4 I had in mind! I think then that there is no one with a knob that unlocks their hubs....the reason for all this mess is that your RIG identifies slip and grip (to some degree) and continuously adjusts 2wd or 4wd, so.....it needs its pump to provide instant reaction. If the "pump" is truly electric, then can't this be bypassed to run on another manual switch? Then with the error codes just keep then so it does not try to spin the front CV's?? I thought that this pump was driven by the front shafts then selves and this is what leads to problems. If I am not mistake didn't all-modes also come standard with the LSD 4.6's? or aybe in the 3.5 R50 they were still 4.3's with LSD? Link to comment Share on other sites More sharing options...
91PathSE Posted July 29, 2008 Share Posted July 29, 2008 My X GF has an R50, I put manual hubs on that..and worked fine, but it wasn't electronic 4X4, it had a shifter. All mode(automatic 4x4) has to stay auto hubs Manual 4X4(shifter) can have manual hubs. Link to comment Share on other sites More sharing options...

First time I have heard this. If we can be of any further assistance or you wish to order, call or you can order on line at" It some times makes me wonder if AC really know what the hell they are really doing?

BurntTimber Posted July 30, 2008 Share Posted July 30, 2008 Thanksyou got my point though That is bad news, I planned to put on an OME lift, but I have the Auto 4x4 knob on my '03 Chilkoot. Has anyone had experience with the OME lift without the Manual Hubs? I definitely could use another 2 inches clearance on the Pathy so would like to find a way to lift without damaging the CVs.

Dean do you think that it will really be a problem to run the AC lift with out manual hubs? I'm not sure how overheating is related to hubs at all, so I'm confused why they would mention it. I honestly cannot say how risky it is to run the AC lift without manual hubs. However, I can say that I ran my 2" lift with the stock drive flanges for quite some time without incident before deciding to upgrade to manual hubs. The CV angles are still within the normal operating range with the AC lift, so they won't break, but the increased angle may potentially cause the boots to wear faster, so you should keep an eye on them more frequently.

Good call Dean. I ran my lift for almost a year before installing manual hubs & didn't tear up any CV's while running 2" lift coils & stock drive flanges. Although I tore-up 3 CV axles before the lift with stock coils & no man. hubs... damn mud & rocks & sticks & what not... Link to comment Share on other sites More sharing options...
nissandoms47 Posted July 30, 2008 Share Posted July 30, 2008 Ronin, just swap your tcase out for a part-time lol. I've actually be thinking about putting a qx4 knob/lever shift into my xterra because it has a lower 4low ratio then the tx10. IMO I dont know why the auto tcases have a pump. The fluid just gets sloshed up into everything in there. Only difference is that there is a motor that engages the 4x4 instead of a lever on the tcase but im probably wrong. I wanna look at the diagrams a little better when I get home. Link to comment Share on other sites More sharing options...

nissandoms47 Posted July 31, 2008 Share Posted July 31, 2008 idk.. the ATX14A is a very complex transfer case. Its almost like a mini automatic transmission. It has a valvebody and everything. I cant see exactly in the FSM that the main oil pump is driven off the front driveshaft. There is a sub oil pump that probably turns on when the main oil pump isnt working right. best way to tell if you have problems is take your drive flanges off and drive around and see if you get the warning light. then if it blinks see what the sequence is and look it up in the FSM and it'll tell you what the transfercase computer is freaking out about.

From this picture it looks like the oil pump runs in between the the main drive shaft and the front drive shaft. But it looks like it runs on the chain so the front would have to be engaged. Don't see any secondary pump. Link to comment Share on other sites More sharing options...
zonianbrat Posted July 31, 2008 Share Posted July 31, 2008 I hope I dont get flamed or banned for this!! Would it be possible to do a mod like this: http://www.explorerforum.com/forums/showth...own+wire+thread It basically electrically tricks the computer and gives you true 2 wd. I'm debating on doing this my my Explorer since I have a similar Auto 4x4 feature. Seems alot like the Auto 4x4 on nissans but I am sure things in there are different. Thought I would throw it out there. Link to comment Share on other sites More sharing options...
parthy Posted August 5, 2008 Share Posted August 5, 2008 (edited) Here in OZ we use FWH on our R50's with all mode all the time the 4WD light comes on but dont worry about it here is a link to our pathy site that may help .

kevs03pathy Posted August 11, 2008 Share Posted August 11, 2008 I have had manual hubs on my 03 pathy for over a year now and have had no problems and yes I only have the knob set up. Just have to remember to lock the hubs before you switch to 4wd. Return knob to 2wd and unlock the hubs. I have the OME lift if that makes a diffrance to anyone.
