Do 97-01 CR-V hub/bearings fit in an Integra knuckle? Want to use 36mm RSX-S axles.

Background:
I've got a 93 Del Sol Si. I've got the full USDM Integra Type R suspension (struts, forks, front knuckles. 5 lug hubs, front and rear lower upper and lower control arms, trailing arms, sway bars and 2.98 lock-to-lock steering rack plus the ASR brace to keep the rear sway bar mounting points reinforced). So, this means I have the 5-lug hub with 32mm spline at the moment.

Reason:
I'm thinking of going 36mm spline as I've read a lot of issues with the 32mm ones (aftermarket and OEM mix-n-match combos). I heard the RSX-S axles work well with the Hasport EGK1 mounts. And that extra 4mm puts my mind at ease as well as the cost of only having to look for one set of axles.

Question:
Rather than picking up the JDM ITR 5-lug knuckle/hub assembly, I was wondering if the 97-01 CR-V knuckle would work (junkyard) or possibly brand-spankin-new CR-V hubs and bearings. As far as I know, the CR-V shares the same caliper and rotor as the ITR. It also shares all that plus the bearing with the 97-01 Prelude. I have mixed feelings about the junkyard. I'm sure the soccer mom that owned the car never purposely abused it but hey, she did smash the SUV up.

I believe all Integra knuckles (at least USDM, part 51210-SR3-N10) are the same including ITR.

I have the hub and bearing part #s for the CR-V, Prelude and DC2R.

36 mm CV spline (1997-2001 Prelude/CR-V):
44300-S47-008 BEARING ASSY., FR. HUB
44600-S47-000 HUB ASSY., FR.

32 mm CV spline (1997-2001 USDM Integra Type R):
44300-S5A-004 BEARING ASSY., FR. HUB (KOYO SEIKO)
44300-S5A-008 BEARING ASSY., FR. HUB (NTN CORP.)
44600-ST7-R00 HUB ASSY., FR.

So, I was wondering if anyone could grab the hub and bearing part numbers for the JDM ITR (whichever years had the 5 lug version) OR provide the measurements for the inner and outer hub diameter for the CR-V. I guess there's a 3rd option too which is letting me know if the knuckle geometry is identical for the mounting points (like steering arm, ball joints and hub)?

And a final question... I know for the Base RSX 32mm axles that you want to swap the inners (tranny side). Do I want to do this with the Type-S axles as well? What issues might I encounter with this setup?

check with Circuit worx and see if they carry them. If not, they might be able to make you a set. I know they do carry the 4x100 and 4x114 36mm hubs. But not sure about 5x100 or 5x114 36mm hubs.

I wanted to update this thread to support my findings... Also, it'll help me find this post again more easily...

JDM DC2R knuckles are just like 97-01 CR-V knuckles. They are different from USDM DC2R knuckles. I have opted to not use my ITR knuckles and went with the CRV instead.

Also, for anyone curious, the 97-01 CR-V hub can be made into an RSX-S hub by removing material. They are virtually identical. Plus the RSX-S hub is a lot cheaper! I'm thinking about doing an RSX-S or TSX brake conversion as well but I'll need a smaller RSX-S hub. Also, I believe base RSX hubs are the same as RSX-S hubs but take a 32mm spline.

Notice how the CR-V hub has a wider center bore and wider hub surface? This means rotors like the TSX rotor will not fit on the hub without opening up the TSX rotor's center hole. An RSX rotor's hat will not even clear the wider hub surface, let alone the center bore.

One last thing. The back of the CR-V hub is identical to the RSX-S hub. They fit within the same bearings.

Very good info and thanks for your help. People like you, thats what k20a.org is all about:up:... Instead of shaving the jdm itr hubs to do the rsx rotor swap, I just press out the jdm hub and pressed in the rsx hubs.....

I know its not the right way, but it works for me...

Yeah, the RSX hubs seem more versatile and they're much cheaper. I reposted this info because I was looking for my post again and it was hard to find. :)
