Dumb noob engineering/machining question re bolt on wheel bearings


GARDRB

Recommended Posts

So my ADHD and I went down to Zebra this afternoon in a medication-fueled bout of enthusiasm and pulled apart a Camry and a Corolla for a dumb project I've been dreaming of for years involving a 5x114.3 AE101 Corolla.

I came away with two rear wheel bearing/hub assemblies, the one on the left from a Camry which is 5x114.3 and the one on the right from a Corolla which is 4x100. I tried the Camry hub assembly on the Corolla hub carrier and the first thing I noticed was that the ID of the hub assembly is 2mm bigger, and then that the bolt spacing on the horizontal is slightly wider.

I also grabbed the hub carrier coz why not?

So my questions are, can I adapt the spigot with a ring so that the hub assembly is a nice fit over the spigot (I assume I can't make a 1mm thick ring that goes between them to space it and will most likely have to get the hub assembly machined out to allow an adapter ring with more thickness? 

What is the best way to deal with the differences between the bolt patterns? I assume since the hub assembly spigots on that the job of the bolts is just to hold the assembly to the carrier so the spigot can do all the work? Can I oversize the holes in a way that makes them line up and use larger hardware? Go easy on me, I can bolt things together but my strengths lie with computers and websites.

PS, paging @shrike coz I know you've diddled around with stuff like this on your car, but different coz I'm content with FWD for now.

Might be a dumb question, as it's been a few years since I built a rotisserie with two of these. But do you even need to swap those parts over to get the new stud pattern? Could get lucky with the stub axles or whatever they are call them swapping between them?

I spent about 5 mins smashing away at it with my small sledge to see if I could get the drive flange from the 5 stud hub into the 4 stud hub and it was not successful. So it’s not a dumb question, I’m gonna look into different bearings too and see if there is one that fits the Camry hub flange into the Corolla bearing mount

I’m currently getting rx7 hubs adapted into the b1600 spindles. Luckily the difference was great enough to machine up a sleeve style adaptor.

”the machine shop” in Hamilton is doing this for me.

i know what is required and how to get it done but lack a lathe and lathe practice to get it done.

Yeah if you can source bearings to suit it could be a good goer.

@GARDRB rears are harder then fronts, I think Barry at MRP converted his rear from memory and I thought it was Camry gear or he redrilled the rear drive flange to 5x114.3 but might have been FWD 90's Rav4 parts (Edit, had a look on Toymods and Barry said the rear factory flanges are too small to redrill)

Im using Toyota Highlander/Kluger drive flange/bearing hub in ST205/ST185 GT4 celica rear knuckles/hubs (bolt pattern is the same but 5x114/3 instead of 5x100), did the highlander come out with a FWD version?

Whats the OD on the back of the Wheel flange (the part that has the studs sticking out) can you press the 5/114.3 one into the 4x100 carrier or bolt it in by the looks of the below diagram

Rav4/celica bearings are a larger OD on the front but the same ID as the AE111 and I think AE101 ID, AE111 OD of the bearing is smaller (reason im using ST185 front knuckles is so I can use larger bearings)

If you measure the OD of the Wheel stud flange spindle on both you might be able to get the 5x114.3 one turned down on a lathe

in no way commenting on legalities, but if you cant find a bearing with the correct OD to suit the 63mm bore, and correct ID, you could yes press in a new sleeve into that carrier... However its is a litttle bit of work.  Ideally would want ot bore it out larger to make the sleeve thicker, (enough to scotch key it)  press in new sleeeve and then re-bore to correct interferrence fit.   If you dont make the sleeve thicker than the 1mm - not ideal as the wall thickness is so thin chances are will come out if ever changing bearings in the future.  ( may never be a problem ), but this is crap idea. Definately should be able to get the correct size bearings to do that job. Have a good chat with the team at SKF bearings in lady ruby drive auckland. they used to be absolute GC's. 

Bolt holes. Being as the 5stud setup is larger width, there is enough material to re-drill the correct pattern in a mill and a slot drill. Personally i wouldn't 'slot the holes' but given there is only 1mm each hole its probably not enough to matter that much, but would definitely use a 10mm cutter so better fit on the bolts.  Assuming the bolts are 10mm thread, they will be 9.8mm OD so will go in the 10mm holes fine.  This is my presicion eng brain kicking in here and probably completely unnecessary and 10.5mm hole be fine.

joys of a failed memory
done an AE101 to 3STGE+ 5 stud about 15 years ago

front was easy, just used celica hubs with a concocted CV ...... and fecked if i can remember rear combination. this may have been 5 x 100.... can't remember celica/MR2 and maybe Rav4?

Ok, this morning's learnings.

The rear hubs don't use a removable wheel bearing, the races are part of the bearing carrier.

The ID of the Camry bearing is 30mm vs the Corolla's 28mm

Interestingly, the previous gen Corolla has a removable wheel bearing sized 28x61x42, so if I could find a 30x61x42 bearing I might be in business if I used older bearing carriers. Or keep searching for a carrier with a 30mm ID that fits the Corolla hub carrier

Also the previous gen Camry has a removable bearing that is 30x63x42

So I took it to my engineering shop of choice, and he said "fuck yeah, I can do that, fun car shit" and when I asked how much he said "fuck all, coz I wanna be part of something cool"

I’m following with vested interest; I plan on swapping mine to 5x114.3 one day too. 

Honestly, it’s probably not worth the effort, but it’s kinda been an obsession of mine for a good 20 years and r33 wheels on a Corolla have gotta be good right?

So because this isn't my main project, we went for some spigot rings to get the wheel bearing carrier to spigot onto the knuckle. I'll have to "enlarge" the bolt holes in the bearing carrier, but because it all spigots, those bolts just have the job of holding the bearing carrier to the knuckle. So for my next trick (after taking the spring out, mounting the hub and wheel and posting photos on the 'gram), is to try and find a rear brake caliper with a 139mm bolt spacing and a built in handbrake so I don't have to run all the grot that is the internal drum handbrake from the Camry. If all else fails I could always go and get the complete rear brake assemblies from the camry down at zebra.

I think ae111 and ae101 rear calipers may work
