fiveoneohray Posted January 22, 2009 Report Share Posted January 22, 2009 (edited) Hey I need a complete rear axle minus leaf springs from a 521 truck. I am modding it to fit in a 510 wagon. I want basically everything drum to drum and everything in between. Pm me with what you have and it kinda needs to be in WA aiee now i look like a douche bag! I meant to post this in the parts wanted! Sorry :o Edited January 22, 2009 by fiveoneohray Link to comment
datzenmike Posted January 22, 2009 Report Share Posted January 22, 2009 Not the same width are they? Link to comment
69FJWagon Posted January 22, 2009 Report Share Posted January 22, 2009 From What Icehouse said they are very close,I am about to dive into the same project for my wagon as soon as I get my girlfriends engine done and installed the hardest part for me is going to be turning the axle hub down and redrilling for the four lug pattern...I hope :blink: Clayton Link to comment
ppeters914 Posted January 22, 2009 Report Share Posted January 22, 2009 I'm curious: why replace the wagon diff with the truck diff? Ratios? Link to comment
sdsurf Posted January 22, 2009 Report Share Posted January 22, 2009 I have the axles, housing, brakes, etc. I do not have the third member. Let me know if this would help. Link to comment
datzenmike Posted January 22, 2009 Report Share Posted January 22, 2009 (edited) I'm curious: why replace the wagon diff with the truck diff? Ratios? The H-190AL rear ends were used on Roadsters, wagons and 520/521 and early 620s. The carrier is aluminum and the truck uses 4.875 gear ratio, the 'goon uses 3.889 for automatic and 3.7 for 4spd. The 'goon differential differs from the truck by having 23? spline side gears whereas the the trucks use 29. So the axles are different too. A truck 4.875 diff could easily be installed in a 'goon by knocking out the roll pin that holds the pinion shaft and removing it. Rotate spider and side gears and thrust washers out, substitute 'goon side gears and rotate back in, install pinion pin and new roll pin.. done. Edited January 30, 2009 by datzenmike Link to comment
fiveoneohray Posted January 22, 2009 Author Report Share Posted January 22, 2009 (edited) Reason being is there are no good solutions for a LSD setup in the wagon. Tested welded in a wagon with a NA CA18DE and it snapped several sets of axles. Right where they have the splines since that is the smallest part. I am building a VG34 hi comp engine and looking for around 285hp to the ground. Those axles are gonna snap. Basically axle size and LSD or locker options are there as opposed to the wagon. They are pretty much the exact same width so no problem there and the hub just needs to be turned down and then re drilled which is no big deal. Then the leaf spring mounts need to be moved. I will just do the rear disc conversion to finish off the rear. SDSURF Thanks but I need a complete setup. Rather be local also :D DAZENMIKE I looked into that route but when you buy a LSD the housing is totally different and you have to use the truck axles as you cannot change the splines due to they are built into the LSD housing. One more horrible fact to the wagon diff. Axle bearings are available but the retaining collars are no longer available. Service manual says to cut off the old retainers to remove the old bearings. Pretty much useless. Edited January 22, 2009 by fiveoneohray Link to comment
ppeters914 Posted January 22, 2009 Report Share Posted January 22, 2009 Ahhhhh....that makes sense. Appreciate the explanation, Ray. That's gonna be one powerful wagon. Hey! Tana is in LA until next week. We could pull the diff from her 521. Think she'd notice? :D Link to comment
mklotz70 Posted January 23, 2009 Report Share Posted January 23, 2009 mike.....the U.S. didn't get the 3.7 from what I understand...we weren't that lucky :( I'm hoping you know something I don't.....the last time I looked at a diff, the ring gear has to be pulled to get the pin out....or did I look at it wrong? I've got two diffs sitting in the shop waiting for me to do the spider gear swap so I'm hoping you have a trick :) fiveone.....when I did the bearings on my rear end, I reused the collars. I used the shop press to push down on the spline end and some blocks under the backing plate....put some pressure on it and then his the collar with some heat. The first one took a bit of heat, but he second one.....I swiped the flame across it once and it popped. I then used a piece of thick wall sq tube to slide over the shaft and hammer the collar back down. It took some hammering, so I wasn't worried about it having be damaged by the heat....I didn't get it read or anything. But, that still leaves you with weak axles. If you want some beafy axles...get the ones out of the hardbody and have them shortened and resplined.....they are MUCH thicker than the 521's!!! Any 521 with the L series in it would have 4.39's in it. The 4.89's went away with the J13. Link to comment
datzenmike Posted January 23, 2009 Report Share Posted January 23, 2009 (edited) Darn you mike! :D Yup the ring must come off. Must be thinking of my old Dodge. Yeah the bearing caps have to come off. I guess mark them so they go back in exactly the same position. With that many bolts, you should be able to unbolt the ring and get it back in the same position. Scratch mark it too. Also, yes the J13 got the 4.875. I think the reason the 'goon splines broke was because of the welding. An LSD would fix that but they're not available. The '82-'83 200sx went to H-190s I hear. I don't know what spline was used nor the width or axle length. Sure would be nice if the axles were 31 spline and were the same length as the wagon. Four bolt too!... just throw in any truck 3.889, 4.11, 4.375. Oh... here's an H-190ALuminum case w/LSD: (wouldn't you just love one?) http://i138.photobucket.com/albums/q251/datzenmike/rearendNissanH190aluminumcarrierLSD.jpg[/img]"] Edited January 23, 2009 by datzenmike Link to comment
mike Posted January 23, 2009 Report Share Posted January 23, 2009 Strength vs. cost vs. parts availability... Have you checked into some sort of domestic axle shortened? 9", 8.8, narrowed yota? An old vega axle? I talked to a guy the other day who was doing a v8 swap and said s10 shafts fit and will hold up to a decently built small block...I dont know this for fact its just what the guy said. The money you save getting a 521 rear housing will be lost when you buy a LSD for it. You could probably get an 8.8 out of an explorer with an LSD (some came stock with an eaton) and a decent 3:something or other ratio and have it shortened for close to the same cost or cheaper... Also 8.8s have readily available (no guesswork/waiting on parts) aftermarket. Is there an "everybodys doing it" swap for rearends on these things? Link to comment
mike Posted January 23, 2009 Report Share Posted January 23, 2009 Oh yeah, the reason I was going to reply in the first place, theres a complete 521 rearend in a yard in spokane for $50 if youre interestedIll give you the info... Link to comment

fiveoneohray Posted January 26, 2009 Author Report Share Posted January 26, 2009 yeah i was just dying installing a NOS lsd in a customers wagon.....every minute was killing me. well i will see what i can find. I will make a technical article when I do it. Link to comment
]2eDeYe Posted January 26, 2009 Report Share Posted January 26, 2009 Guess you do want the whole thing. :lol: I sent a message to a buddy to see if he wants to do you that favor you for a bit of $. I'll let you know. Link to comment
Fineline Posted January 26, 2009 Report Share Posted January 26, 2009 The 'goon differential differs from the truck by having 29 spline side gears whereas the the trucks use 31. So the axles are different too. I believe the goon h-190 had 23 spline axles and the truck h-190 has 29. The 31 spline axles came in the H-233b. Link to comment
datzenmike Posted January 27, 2009 Report Share Posted January 27, 2009 (edited) Yes, my bad. I Have a 233 rear disc from a Path that I am planning to put under my 620 and with all the mixing of parts the lines blur. Has anyone looked at the late S11 rear ends. I believe they went to H-190 in '82-'83. The axles are disc brake and 4 stud and I don't know the spline count. Edited January 27, 2009 by datzenmike Link to comment

datzenmike Posted January 30, 2009 Report Share Posted January 30, 2009 I've just found out that the 200sx from July '81 uses a truck H-190 carrier and side gears. This means the axles are splined to match the truck diff and are 4 bolt. I don't know the length. Link to comment
