I've been gathering dimensions for wheel bearings, hubs and knuckles. I haven't started on the knuckles yet so this is still in progress.

Measurements are all in millimeters.
ID = Inner Diameter, OD = Outer Diameter, IW = Inner Width, OW = Outer Width (assume same as inner width unless stated)
Bearings:

You can determine the size of the bearing this knuckle can take based on the inner circlip part from the front brake section or in some cases, the knuckle section of your favorite Honda/Acura part list.

any updates? I sure hope the axles I bought (from a 3rd party) work being that I need to run the smaller bearings

I wish I the info on the hubs was easier to find. But we can extrapolate most of that information (and that of the knuckles) based on the bearing. If people wish to add to this, please do so. I stopped researching when I found a working combo for my setup (97-01 CRV knuckes, 02-06 RSX-S or 02-06 CRV hubs and CRV/RSX bearings).

I want to add that most 5 lug setups are interchangeable with that setup. I can use an RSX/TSX/CRV rotor and caliper setup among others. Some exceptions may be with factory Brembos.

anyone have a wheel hub out of the bearing and spindle to measure and write down some dimensions.
for my rwd civic im wanting to put s2k front hubs in my crv knuckles. through honda automotive parts.com the crv and the s2k both use the same bearing and circlip. so im prety sure it will work. i have the s2k hubs already pressed out. but son't want to press my crv hubs out of the brand new bearings if its iffy. looking for the dimension from the hub face to the surface the race of the bearing sits against on the hub. basically making sure the ofset of the hub is the same.
doing this will allow me to not have to use an outer cv as an axle stub to hold the wheel bearing together. the s2k hub has threads on the end for a nut, and isn't hollow or have an axle spline.

here is the s2k hub showing what im talkin about.








yes i know this is nothing usable for anyone unless ur using crv/itr knuckles maybe possibly an element and don't need an axle up front.
just need to know some dimensions before i try to press them in.

from the face of the wheel hub where the rotor sits to the step where the bearing inner race sits im measuring about 20mm with my caliper. prety much the only dimension im concerned about.

scorge..... can you try to get me some specs of a bearing? oem honda part #44200-S3Y-008 ntn bearing. from a 2000 honda insight. need to know the basics. Inner ID, Inner width, Outer OD, outer width.

hopefully its got a 43mm ID and not the small 38mm ID the older civics/crx's had. even though insights are known to have small spline axles.

insight front knuckle.....hmmm


like i said hopefully it has the civic/integra size bearing dimensions even though it is a bolt on bearing like an accord. and I can take my rsx-s wheel hubs and turn 2mm off them and get them to press into insight bearings.
or better yet turn the 2mm off the s2k front hubs and press them into the insight front knuckles for my rwd civic, no axle stub needed. pics are posted somewhere in this post

Yeah, it's because it's a bolt on bearing I can't find the inner dimensions easily. If you have it on hand, try measuring it yourself. You may want to round up since it's supposed to be on the tight side.

As for the S2K front hubs, they'll definitely work in your CRV knuckles but I'm not sure how it'll align with your calipers. I know the S2000 rotors are different from the RSX-S's fronts but I'm not sure if this is because of the S2K's knuckle design or if it's because of the S2K hub. If you have a CRV/RSX or JDM ITR hub, set them side by side and see if the shaft that goes into the bearing is offset.

This is for your F22 project, right?

yep, for the f22 rwd civic. the s2k hubs will fit the crv, rsx-s bearing. same bearing part number. but the hub would have to be machined some to fit the knuckle, it hits on the backside. oh, and their longer (wider) so that plan is a no go for the s2k hubs in the crv knuckles. and im wanting to scrap (sell) the crv spindles once i get the insight aluminum knuckles to work. and yeah sucks since its a flanged bearing, I can't find the ntn number thats on the side of the bearing to look up the specs. And right now im trying to do my homework before i get the knuckles so i know what im getting myself into.
my question what is the reason why honda went with the bigger bearing? is it because the axles got larger and more splines, so to keep the same matrial wall thickness of the hub they increased the bearing size, OR did they increase the bearing size because of the weight of the vehicle.
look at it this way, the early civic and crx dx, dinky bearing, wheel hub and axle. it weighs nothing. honda upgraded to the larger civic bearing compared to the crx bearing also increased axle splines. the car weighed more. then out comes the itr, car meant to handle and corner gets an even bigger bearing. so does the crv, rsx, ect weight and hp both increased.
is there any logical reason why the s2k uses the rsx-s wheel bearing. is it because of load and sizing, or because it was readily available and already produced?
what im getting at for my ek, will it be ok using the dinky insight wheel bearing for the weight of an ek, or does it even matter about bearing diameter and size since there is no axle up front anymore.
since the s2k wheel hubs are solid i can turn them down to fit the insight front wheel bearing. but then again that is a lot of material going from 45mm od on the hubs to 38mm . that is if the insight shares the same bearing dimensions as the crx dx.

How are you planning to get the Insight knuckles to work? Isn't that designed for a MacPherson setup? Anyway, I don't have the answers on why the bearings got bigger.

Why not get base RSX (32mm) hubs and use the rear thing-a-majigger found on FWD CRV's? I think it goes in where a rear axle would go. HondaPartsCheap calls it a rear axle shaft? Part # 42332-S10-A01. I don't know the size of their rear axles but it can't be 36mm from what I've heard. Also, similar part # for 02-06... 42332-S9B-003.

yes the insight knuckles are mcphearson strut, which is perfect to adapt as there is already a spot on the upright to bolt something to. im goint to fabricate out of 4130 molly plate the upper section that will go from the knuckle to the upper ball joint in the upper control arm. will look similar to the upper section of the fabricated knuckles Nitro Drivelines used to make.



also the insight has the lower balljoint in the lower arm and not in the knuckle like our knuckles are, but... the insight uses a steel insert for the tapered part of the ball joint shank. this has already been pressed out on the knuckles im getting. im going to machine the opening to accept the standard civic lower ball joint. if need be ill have to add material to the bottom of the knuckle if it gets too thin.

and the reason for wanting to run the s2k hubs is because there is no need for a stub axle, outer cv, to hold the bearing together (extra weight)
also depending on the size of the insight wheel bearing, if i have to turn down the hubs to a 38mm diameter the wall thickness will be very thin. so since the s2k wheel hub is solid turning it down yes is still removing a lot of material, but there is still more material left than messing with a rsx hub with a stub axle through it. as for the crv rear. yeah they show the axle stub through the rear bearing but i don't know what spline it is, and of course since the rear wheel bearing on a crv is a bolt on also can't find any info about it.

i guess ill just have to eat it and get the knuckles for the 150$ wait for em to get here and go from there. goal for me is the light weight forged aluminum knuckles on the front of my civic, 5 lug, and acura rl calipers and a 2 piece rotor.

im not a member on honda tech, but there is a guy who used crv components on his del sol i think to do the awd conversion. maybe i can find the build again and have a friend message him and see if he has any dimensions on the rear bearing.

well just got some little bit of conformation on the hub od/ bearing ID. guy selling me the insight knuckles put caliper up to them with the hub still in the bearing and got rough measurement of 1.4" = 35.56mm.

but lets say i don't use rsx-s hubs with the larger axle, but i use rsx base hubs with the smaller spline axles and turn town the hub from 45mm to 35.56mm, i end up with a hub that fits the insight bearing and still has a 3.95mm wall thickness. can also do this to the s2k wheel hubs and have a solid center with no axle or splines. < liking this route better and not having to use the outer part of a cv turned down to act as an axle stub.

then i thought, why not go see what size a rear spindle is, it supports the same weight just doesn't have a drive axle, and doesn't see steering forces.
so i measured it and, they measure 27.9mm. thats prety small. so hopefully the 35.56mm of the insight front bearing will be enough for suspension and steering duty on an ej8 coupe.

im beginning to think honda only increased bearing size because the size of the axle got bigger. and the s2k got an rsx, crv. itr front wheel bearing because it was readil available and on the same weight car. also they probably started of with the same blank for machining the wheel hubs as the rsx and ade simple changes to it instead of redesigning a whole new part.

the other reason for the insight knuckle for me is because it does not have a steering arm. essentially i can put one where i need it and thats on the same plane as the lower balljoint because my steering rack is now dead even with the lower control arm pivot point since it runs under the pan of the f22c.
I can either A weld a billet arm to the insight knuckle or B machine a billet arm that used the wheel bearing mounting bolts. ill be using option B.
I could make the crv spindles work, even the civic spindles. thing is im not happy with the weight, and adding a 2" long spacer to the steering arm atatchment point im not comfortable with. would it work yes, would i be leary with most definately.

and lastly there any do's and dont's to lightening a wheel hub, like scaloping the hub or drilling holes in it like the rear drum hubs. I mean the rotor is what gets the wheel forces, and transmist its forces to the wheel hub centering ring. and yes the lugs have some force too. but the face of the hub shouldn't have to be full circle or have material or as much material between the lugs.

insight hub has been lightened

so has s2k hub, would like to lighten it some more


want to put holes like so in the hub

Hi!

there is no IW or OW for the parts :
44300-S5A-004
44300-S5A-008

Anyone can chime in?

and while I'm at it: I was thinking of going 11.1" rotors on my 99 Dx coupe.

I know we can use ITR calipers, stock brackets, MINI '07 rotors (280mm) but I need to have the 10.3" hubs. (this btw doen't need any hub ring or special brackets.. ;) )

I was contemplating the idea of switching only the hub from a Civic SI into my DX knuckle. Am I stupid? Could this be done?

EDIT: never mind! Enough googling showed me that to fit the SI hub would mean fitting the SI bearing too, which doesn't fit in a DX knuckle. Unless I machine the knuckle but it's easier to simply put the damn hub ring...

May I ask, what's the bearing part number and size for a civic ep3 type r

The table at the start of this thread that brought me Here has me confused.

Any help appreciated

Phil
