Free wheeling hubs

I bought a set of "Samurai" hubs from Trademe last year and decided to fit them last week. They went on fine (I thought) but, by coincidence had a brake problem on the same wheel the next day (okay I thought 1 mm of pad thickness would be enough for a few more ks - it wasn't and the whole pad slipped out). I decided to check the wheel bearings at the same time and as I removed the new free wheeling hub noticed that the axle circlip had pinged off. On closer inspection there is not enough axle showing to expose the groove for the circlip to fit on (it was dark when I flung it all together). The inner sleeve that fits over the axle splines projects outwards a few mm more than the standard Sammy one does.
Fortunately I have two other sets of hubs so its not a major but now I'm wondering if what I bought is actually for the >96 Sammys.
Everything else lines up but there are no markings on the hubs - not even a manufacturer. They are black, and have Allen screw heads holding the outer hub to the inner so I suspect there is a difference and may well be able to use them on my Jimny instead.
Anyone else had this problem?
Cheers
Steve.

Just wondering about fitting some of these to a vitara. I understand there is a clearance issue with the SJ hubs on the vitara (circlip on axle) but is there a spacer available to allow the CHEAPER and more readily avaliable SJ hubs to be fitted?
I have seen a write up somewhere but cant find it anymore.
Any one made spacers?

i fitted sammy 'aisin' hubs to my escudo.
behind the hub, on the drive shaft, is a circlip that stops the axle pulling through the bearing and out of the hub.
when i fit the hubs the inner guts that slide on the splines made contact with the circlip, and i tightened the outer housing bolts up and the hub inner cracked
what i did though was use a bolt in end of the shaft and make up a T shaped collar (a thick washer would do really) and stop the shaft from sliding through that way. (if that makes no sense------pull your hub off and you will see what i mean).
i got my hubs for $100. cheapest i could get escudo ones was $200.
pm me if you need more info, its a piece of p1ss to do though, and ive never had any problems with mine.

Yeah I remember you telling me. That was part of the reason (the price) I figured the sammie ones would be best. I wonder if I could machine a little out of the sliding part to allow the circlip to remain in place without weakening the hub? Might just make up a couple of Spacers from light guage steel. Need to measure the thickness I need first I guess.

Machining 3-4 mm off the sliding spline would work for me. I was just wondering what my hubs were really made for.

Of course I could machine the back edge off the auto's I have and use them for spacers. That's assuming I can get them cut off perfectly square or find someone to do it. Could be a business opportunity there for someone with time and a lathe. Send in your autos with cash and receive a spacer in return.
Then any hub would fit without fecking around.

Sounds like they might be coily hubs Steve. Coily hubs are black, and from memory have torx screws holding the cab on to the body.
The stub axles, bearings and CV stubs are all a bit different on the coily by a couple of mm. Not sure about the hubs, but that sounds like a likely explanation.

Pulled the auto hubs off today (had to do the drivers side to do a spring change). Not much too them. Will swap for manuals when I can get some I think. Might see what machining of the inner would cost when I get them and then forget about the problem forever. Until they break of course.

with all this faffing around maybe getting the shafts machined to take the circlip at the outer end (like the samurai's stub axle ends) would be easier.
on a positive note I made up a tool (okay a guy at work did the machining for me) to remove and retorque the bearing retainer (the doohikky with the four holes).

Hmmm, all this seems awfully confusing to a newbie, could anyone post up some pictures of what they have done? (I don't know the inner workings of hubs)
I have a set of SJ413 aisin hubs, a set of SJ413 avm hubs and an escudo that I want to swap from auto hubs to manual.
I was thinking about selling the SJ413 hubs to buy Escudo hubs, But if anyone has a cheaper easier option that would suit me I am listening

Basically remove the old autos.
remove the circlip and the spacer washer.
put new manual hub on (may need gasket/ gasket goo to seal)
put a bolt (M8 or 10 from memory)and washer on outer end to pull the shaft in tight.
put outer cover plate with switch etc on.
You now have manuals (of course this is simplified and will take about an hour each side) Take the time to replace the bolts and spring washers while you are at it with new ones (or inner hex head ones) and dont loose the cup washers if you have some, which you probably wont if you didnt get any with the manuals as the autos just have a straight hole for the studs to pass through unlike the manuals.
Get out there and whip one off. have a poke around and then decide if it's too hard for you. Bet it isnt.

Send me an email at
davo@clear.net.nz and I will send you a picture of the different hubs (plans) showing the circlips etc.
