Name that Half Shaft, Win a Prize!

A while back I bought several new DSS half shafts that were marked with a part number that corresponded to '88-91 Civic/CRX's. I recently went to use one on my CRX and it didn't fit. Everything is the same except the trans end is a slightly different size. So then I was thinking they must fit an auto trans, but they don't.
Here's the differences: We'll call my CRX shaft "A" and the other one "B"

Splined OD - A=1.025", B=1.100"
Splined Surface Length - A=.485", B=.492"
Seal surface OD - A=1.380", B=1.580"
Seal Surface Length - A=2.130", B=2.172"

Whoever figures this one out gets a free, brand new half shaft!

Half shaft? John Bobbitt. What do I win?

Wrong dimensions.

Honda Pilot?

It must be for some heavier or more powerful civic based car. This isn't some sort of powertrain swap part is it?

Here's a picture comparing the two.

I'm assuming it is a passenger side axle, and of so it is probably from an Integra. Outer joint is the same, but inner is larger on the b series. Lengths are very similar.

I got it.......its named bob,or robert. What do I win???

He looks more like a Rod

Thanks (ahem, to some of you...) for the responses. It does sound like it might be an Integra axle, but to win the axle itself (or the cash equivalent of what I end up selling one for), I need to know for sure, so please post if you know. Thanks!

1988 AWD Civic Wagon. The larger end is due to the reinforced hubs used.

Seriously, nobody said John yet?

Nope, unless the 88 is different than a 90. My Dad has a AWD '90 wagon, and it has the same splined end into the auto trans as my CRX does into the 5 speed.

You know, I get just a little excited every time I see that someone has responded to this post, because I think that maybe this one will provide the answer I'm looking for. "Steve" Isn't the answer I'm looking for....

I don't have any of them fancy measuring doohickeys, but I went out an measured an axle from my Integra and my eyeballed measurements and drunk math seem pretty close to what you've got. While the SiR was available in world markets with a B16, there aren't any direct replacement axles for EF chassis civics and CRXes with B-series transmissions. People either had to make do with DA Integra axles (with dust shields removed and a potential for binding) or order custom hack-jobs that were usually combinations of inner joints from 86-89/90-93 Integras and 88-91 Civic outer joints. I'd gotten mine from Hasport, but I'm fairly certain that DSS, Raxles, and others made them as well.

So, if you say that this is marked as an 88-91 CRX axle but it has a larger inner shaft for B-Series transmissions, I'm guessing that it's a hybrid axle made for B-swapped EF civics. As such, it's slightly shorter than an Integra axle of the same vintage and is useless to me, so I don't want it. But there's your answer.

eta: For reference here's a picture I took a while back of my Integra axles so I'd stop getting them confused. It does indeed appear to be a passenger-side axle.

Thanks for that information - Very helpful! I'll have to check into this further. But I have a related question for you, since you seem to be up on it. The D16 in my CRX appears to have the threaded holes in the block to accept an intermediate shaft. Is it possible to add one from a Teg or something else to attempt to reduce torque steer? Have you ever heard of someone trying that?
Also, how much longer is the Integra shaft than the Civic/CRX?

I figured if I sounded authoritative, he would go for it. I totally made that up.

It is obviously Honda Part #3730267840-B!

The DA Integra intermediate shaft won't fit. The 86-89 Integra has an intermediate shaft and is nominally a d-series, but I checked and, like everything else with that stupid motor, it's a D in name only and none of the bolt holes line up.

The DOHC ZC also has an intermediate shaft, and lucky for you the block is essentially identical to the D16A6 block. The bad news is that the DOHC ZC transmission only accepts larger spline (aka, DA Integra-sized) axles, so the intermediate shaft won't fit in your A6 transmission. Also bad news is that the DOHC ZC isn't native to North America, so you're reduced to paying import prices for import parts.

So, the following should work: DOHC ZC intermediate shaft; DOHC ZC transmission (or, really, just the differential, but I imagine if you buy one you're buying the other); hybrid b-series axles for an EF chassis, like the one you've discovered in your cache -or- DA Integra axles with the dust rings pried out of your CRX knuckles

I don't know how much longer the DA axles are than their EF equivalents, but I know they're not a direct replacement unless you do the dust-ring trick and even then people complained about binding. Also keep in mind that "people" in this sense means "shtuff I read on Honda-Tech 10 years ago from 17 year old kids drag racing their beaters."

Hope that helps.

In reply to steronz:

Thanks again! It sounds like I could also have the ZC and/or Integra intermediate shaft re-splined to fit the trans I have now, no? I only ask because I have the ability to do that where I work. Have you ever driven a CRX with this done to it, or with the ZC trans/intermediate shaft? Does it reduce the torque steer? Obviously, I'd only want to do it if it helped.

You'd have to start with the ZC shaft, but yeah, it sounds like that'd work.

I don't have a direct comparison -- I last drove a stock Si in 2001, everything since then has been B-series powered. I know that torque steer isn't really a concern for me right now, but I don't know if that's because of the equal length halfshafts or because I've been driving FWD cars my whole life and I don't know any better.

If I were you, I'd find someone with a stock Integra who'll let you drive it hard. The torque to weight ratio in a 90-01 Integra LS should be similar to your CRX.

I ended up contacting DSS (duh. I should have done that in the first place). They confirmed that they are B series swap shafts for a 88-91 Civic/CRX. So steronz, I know you said you had no use for it, but I'm a man of my word, so if you want a free half shaft, PM me and we'll work it out.
For anyone here that may need one, I'm selling them cheap! PM me and we'll work it out!!!

To add one more bit of info on this, the ZC intermediate shaft is the same as what is used in the 4WD wagon, so I've heard. The reason your D16A6 has the spots for the intermediate shaft is for the 4WD wagon. Our 4WD wagon lemons car, using a D16Y8 and the stock 5 1/2 speed transmission and OEM intermediate shaft, uses a 91 Integra axle on the L side, it was slightly shorter than the 4WD part, which fits our application better as we lowered it about 4".

All I know is that this passenger side shaft did not fit into the trans on my Dad's automatic AWD wagon.
