View Full Version : J30 Hubs ON S14 The How TO (with Pics)

If you own one of the unlucky s14 that are 4 lug,
Read a lot about how the J30 spindles are the same diameter as the s14 so I decided to use my shell as
A mock up to see if a J30 can be used as an alternative to the expensive s14 5 lug
So after a lot of trial and error I think I got it covered .
Why the J30 front hubs instead of the s14, they are abundant at the junk yard and Duh!! Its cheap.
What you Need:
Tools:
32mm, 19mm Socket
chisel or sharp flat head
Grinder/cut off Wheel,
Parts:
2 - J30 front Hubs From any year
2 - 1 5/8” ID washers
1 – Pack of .025” thick 1 3/8” ID, 1 7/8”OD Shims (McMaster-Carr (http://www.mcmaster.com/#spacers/=25a3ca))
(You will use 4 on each side and pack comes with 10)
5 lug Rotors
START
First remove the cap off the hub with a sharp chisel to get to the lock nut

Use the 32mm socket to remove the nut
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02765.jpg
The J30 hub has an ABS ring on it, that needs to be removed. Use a cut off wheel to cut a notch into the ring and use a flat head to pry it apart and the ring should slide off.

http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02762.jpg
The rear bearing seal is also in the way for the hub to be mounted correctly. Remove the seal with a sharp chisel.

http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02767.jpg
Next the spacer for the rear of the hub has to be mad Needs to be about 1/8” thick I used the 1 5/8” Inner Diameter Washer which was thick enough and cut the outside diameter to 2 ½”. I used a cutoff saw and then grinded the outside round
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02774.jpg
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02776.jpg
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02777.jpg
The reason for the spacer is to make the backspacing of the hub as close to stock as it can be so the brake calipers will bolt on.
Stock

J30
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02768.jpg
Next place the new washer you made in back of the hub and place on the knuckle.
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02778.jpg

OR You can do the following!!
UPDATE!
I thaught of a better way to do the rear spacer because it will be harder for others to grind down the washer to make it work.

Here is a pic of what i snagged from the yard
with my hubs! I marked the parts that have to be ground down.

http://i306.photobucket.com/albums/nn259/essforteen/DSC02779.jpg

http://i306.photobucket.com/albums/nn259/essforteen/DSC02780.jpg

Here is how it looks when its done!

http://i306.photobucket.com/albums/nn259/essforteen/DSC02781.jpg

Now you have to grind down the inside edge of the washer to make it sit flush!
http://i306.photobucket.com/albums/nn259/essforteen/DSC02951.jpg

http://i306.photobucket.com/albums/nn259/essforteen/DSC02952.jpg

Now you can use the rear seal but its just going to be there to keep rocks out wont really be a tight seal but here is were you cut the little plastic flap.

http://i306.photobucket.com/albums/nn259/essforteen/DSC02953.jpg


Then do the rest of the steps i did! The hub will feel real tight at first but thats because the real seal is breaking in to the back of the knuckle. be sure to check the hub if its loose and add a shim if you need to..
And you may need to space out your calipers with a washer to clear the rotors.

Then pace the four shims in front of the hub
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02785.jpg
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02786.jpg
Place the lock washer in front of the shims and tighten the nut Then torque to specs.
http://i306.photobucket.com/albums/nn259/essforteen/5%20lug/DSC02787.jpg
Install brakes and enjoy five Lug.

I heard from a few people that the J30 hubs needed to be machined.
Have you road tested the hubs??
Maybe it's kinda hard for me to understand it since I haven't really taken a good look at the measurements.

Thanks for the step by step write up.

since you were forced to remove the rear bearing seal, won't the grease leak out of the bearings and cause them to fail?

The s13 hubs need to be machined because you dont use the J30 bearings you press in the s13 bearings and machine a groove for the lock ring

weird thing is my hubs did not have that retainer ring

But it appears the OP is using this on a S14 so there is no need to remove and replace bearing since the J30 and S14 have the same I.D. on the front hub shaft, therefore no machined groove needs to be made because it already held in the way it was meant to be. Different for the S13 though.

Thats kinda true but the i will over grease the bearing and the rear spacer act kinda like a seal so it doesn't bother me

The car has not been road tested because i just mocked it up on my spare shell that has no engine but will be done to my car next week!

Theres a better aproach to doing this that will allow you to keep the OEM bearing seal, im working on something thats very similair to this for a P11 Infiniti G20, maybe I can get some pics soon.

the bearing seal stops the hub from siting right

i just tried what you said but the inner diameter of the seal is too small and the area where the dust shield is doesnt allow it to enter. thats why i had to remove it.

Even if i was able to use the seal the seal is ineffective if the spindle doesn't sit against it.

This is hard to explain because the j30 spindle is slightly longer and the design is slightly different

I reaally wanted to use the seal but every thing i tried failed so i was forced to remove the seal.

If any one knows how im open for new ideas!!!

Thats why I deleted what I said, I explained it wrong but trust me there is a way that will retain the stock seal. Lemme see I think I have a spare S13 spindle I can snap a picture of its basically the same as the S14 except for shaft diameter.

At the moment I don't have the S14 and J30 setups in my garage to test fit but what about pressing the S14 bearings into the J30 hubs? Will the little disk seal that surrounds the S14 hub fit on the J30 hub?

Thanks

Thats the problem with the s14 the bearing is not removable its built into the hub!
I tried using the disk thing but the whole rear half of the bearing is attached to it
so it doesnt fit in the hub

Did you use front or rear J30 hubs for this?

And will this work for the front and rear on an s14?

The front Ones only work for the front.

You can use the rear also but the hub has to pressed out of the j30 and

pressed into the new bearing for the s14

Or you use the entire upright. It bolts right on and requires no press labor. Ebrake works too, they're the same size as Z32/R32, so you can bolt Z32 rear brakes right on to the J30 upright and have functional a parking brake with just cable modification.

As far as the rears go, the j30 uprights have bearing pressed in them and the s13/14 are bolt ins? Is this correct?

UPDATE:
I re did the setup using the washer that sits behind the nut and grinded the flat spots out to make it round. I did this to replace the custom washer i had to make but i had to space out the caliper a little with washers so the calipers wouldnt rub the rotors. I still used the shimms to make the hub sit tight against the nut but thats about it. ill try and update the writeup so it will show how i redid it. But ive been running this setup scince mid June and no problems thus far i even ran this set up drifting at elToro at the DAIs event. and its still running fine but i do check it often to make sure it is still tight.

so just want to clarify because i plan on doing this this weekend. you took the lock washer from the front of the hub (behind the nut but infront of your shims) and grinded the inside to make if round and then placed it in the back of the hub as the rear spacer? is this correct? was there a problem with the original setup that made you change this? and how many shims did you have ot add to the front to be able to tighten the hub all the way down.? sorry for all the questions, i just want to make sure i do this right.
great write up by the way!
thanks in advanced!

Yes when i got the hubs from the yard i grabbed an extra pair of the washers and grinded them down
Here is what i did

Hey thanks again for the great write up.
I already broke out the rear seal in anticipation of doing this so i would be able to reuse it. Did you have a problem with the original setup? im thinking of still doing it that way since the shims and washers are more readily available than extra lock washers and seals. but if theres an inherent problem with the first method i might have to find those parts. let me know.
thanks!

10-04-2009, 11:14 PM
The first set up wasnt road tested i road tested the set up the second way! If you want you can so it the first way and tell everyone how it goes, but id recommend doing it the second way since you will have some sort of seal!!

well more or less, i meant to say how ghetto this shit is... but whatever, folks always want cheap. i mean thats the whole point of this thread.


my gripe is, if you're going to put a spacer, dont use a fucking washer. machine something specific for this application. i wouldnt feel comfortable using washer-spacer technology on my wheel hubs, but thats just me.

I dont mean to dip up a dead thread..
But i wanted to wait before i chimed in on the verdict.
i did this swap (the original posted moethod without the rear seal) over a month ago and have since put several thousand miles on my car with this setup. works great, no problems, no abnormal road noise and my wheels havent fallen off so im happy.
cost me 70 bucks all together
50 for the hubs (bought them almost a year ago for an s13 but never used them)
20 for the washers and shims off the site provided.

thanks for the write up.

any reason you can't just not spacer the hub and run extra spacers to move the caliper further in?
