hawairish Posted October 9, 2016 Share Posted October 9, 2016 (edited) C200, open. No orange sticker on the diff cover, I presume? Edited October 9, 2016 by hawairish Link to comment Share on other sites More sharing options...
dirtbike23 Posted October 9, 2016 Author Share Posted October 9, 2016 (edited) there is an orange one "use lsd oil only"..jacking it up and spin one wheel they rotate on opposite.. Edited October 9, 2016 by dirtbike23 Link to comment Share on other sites More sharing options...

hawairish Posted October 10, 2016 Share Posted October 10, 2016 Hmmm. Oddly it looks like the 4-pinion carrier found in the H233B (for certain yours is a C200), but the sticker is usually a tell-tale of LSD. Perhaps it is? Was the truck in park when you tried the test? Try putting it in neutral...if the tires spin together while the driveshaft rotates, I'd stand corrected. Link to comment Share on other sites More sharing options...
dirtbike23 Posted October 10, 2016 Author Share Posted October 10, 2016 yes...its on neutral...tried also the bottle jack test with ebrake assist...no success Link to comment Share on other sites More sharing options...

hawairish Posted October 10, 2016 Share Posted October 10, 2016 Not familiar with bottle jack test. What year is your truck? Looks like the diff cover has been repainted and the original sticker was taped back on. Also did a little more research...as far as I can tell, the C200 LSD also uses H233B LSD internals, surprisingly. I'd expect the carriers to look similar, in that case, but it doesn't look like it's got the right clearances for clutch packs. Got any close-up pics?

dirtbike23 Posted October 10, 2016 Author Share Posted October 10, 2016 (edited) bottle jack test..jack up one wheel put tranny in gear and drive off the jack its a 99 (released here in phils).. painted it during my oil change and visual inspection of internal. hope this help..

hawairish Posted October 10, 2016 Share Posted October 10, 2016 I didn't realize the WD21 existed after 95, but I'm seeing Philippine classifieds for a them for up to 04. Interesting! So there wasn't an R50 there? Thanks for clarifying the bottle jack test. Thanks for the other pic, but it's inconclusive. I'd need to see the RH side of it, away from the gear. I can see that it uses a thrust block and runs 4.875 gears (39:8), though. Link to comment Share on other sites More sharing options...
dirtbike23 Posted October 10, 2016 Author Share Posted October 10, 2016 wd21s were released here late 90s wherein it was already superseded..Z24 & TD27 NA are the variant..turbos are japan import & are converted from RH to LHD. there are R50s but are also japs import. ill try to inspect the internals perhaps in near future to answer my confusion.. thanks for the inputs sir..

PathyAndTheJets Posted October 10, 2016 Share Posted October 10, 2016 I think I see springs in that carrier, probably LSD. 1 Link to comment Share on other sites More sharing options...
hawairish Posted October 10, 2016 Share Posted October 10, 2016 I think I see springs in that carrier, probably LSD. Not if it uses the same LSD internals as the H233B (which it does according to the parts websites I use...but seeing as it's a 1999 WD21...who knows!). No springs there, though; works entirely on compression and friction. Can't say I've seen a C200 LSD, though, but that particular carrier looks exactly like a scaled down version of the 4-pinion open that came in H233B. That's why I'm not sure it's an LSD (and it sounds like it's behaving like an open). Those 5 little dots you see in the center would be oil at the ends of the splines as it rests against the thrust block. 1 Link to comment Share on other sites More sharing options...

hawairish Posted October 10, 2016 Share Posted October 10, 2016 Looking good! I like the color...might just be the sky or something, but is it more blue than purple? I think it's the same color as my Frontier. Link to comment Share on other sites More sharing options...

hawairish Posted October 11, 2016 Share Posted October 11, 2016 (edited) This is an open C200 carrier, for reference I don't doubt that's a C200 carrier. Looks like my R200A open carrier, in fact (as it should): But I presume your diff was from your 88? By the late 90's, Nissan had three C200 carriers: 2- and 4-pinion open carriers, and a 4-pinion LSD. (The H233B did the same thing...late 80's/early 90's had 2-pinion open, then they went to 4-pinion for a while, then back to 2-pinion. LSD carrier remain unchanged.) Using a 1998 Frontier as an example, here's the 2wd's 2-pinion carrier: But here's the 4wd's 4-pinion open carrier: Although FSM diagrams should only be taken at face value, the shape of the "differential case RH" piece is pretty distinctive, and both diagrams appear fairly accurately. The final years of the 1st gen Frontier and Xterra, 2004, have the same 2wd vs 4wd open carrier, except by then there was a C200 LSD (and it used the same H233B LSD internals, as stated earlier). Of course, it's hard to know what Nissan did with the Terrano post-1995 (up to 2004?), but they presumably stuck with the same available drivetrains of the WD21, Hardbodies, Navara/Frontier, and Xterra at the time. Still, I don't think that's the C200 LSD carrier, just the 4-pinion open. Edited June 12, 2018 by hawairish 1 Link to comment Share on other sites More sharing options...
PathyAndTheJets Posted October 11, 2016 Share Posted October 11, 2016 (edited) Guaranteed its a c200, its out of the rear axle of my Pickup. Granted, Nissan probably updated the carrier for later models. Edited October 11, 2016 by PathyAndTheJets Link to comment Share on other sites More sharing options...
hawairish Posted October 11, 2016 Share Posted October 11, 2016 Guaranteed its a c200, its out of the rear axle of my Pickup. Sorry, wasn't disagreeing with you on it being from a C200. BTW, I posted up some pics the other day of the H233B carriers here. Notice that the 4-pinion open is strikingly similar to the C200. Link to comment Share on other sites More sharing options...
PathyAndTheJets Posted October 11, 2016 Share Posted October 11, 2016 That was my bad. Reading comprehension is weak today. I bet you're right then, 4 pinion open c200. I'd think that even a toasted LSD should turn both back wheels the same way when its off the ground in neutral. Link to comment Share on other sites More sharing options...
hawairish Posted October 11, 2016 Share Posted October 11, 2016 I'd think that even a toasted LSD should turn both back wheels the same way when its off the ground in neutral. Exactly...if there's even a tiny amount of friction on the side gears with a clutch pack, and it's enough to overcome the rotational resistance of the driveshaft in neutral, then the driveshaft would rotate while both tires rotated in the same direction. If the driveshaft was in park/gear, though, it'd look like an open because the spiders would allow for it, but you'd have some resistance in turning. If it turns easily in that scenario, it's definitely open. Link to comment Share on other sites More sharing options...
