Dorman RAV4 5x114.3 Conversion Manufacturer Issue, We are going to break this case WIDE open Options

[Tigawoods]

This thread is now a product warning thread on the Dorman Wheel hubs for the RAV4.

I have found an issue with the Dorman 930- 419 RAV4 front wheel hubs used in the 5x100 to 5x114.3 conversion.

The studs that come in these Dorman hubs have a tapered shoulder with a knurl diameter that goes from 12.46-12.60mm
The OE replacement studs for a majority of Toyota vehicles is 14.20mm (Dormans listed studs for the RAV4 are 14.20)


Now in the case that you dont plan on having any issue with you hub this shouldnt be a problem for you and happy swapping, but...


********
If you somehow break a stud or need a replacement for any reason, the hub either needs to be replaced or re-bored
If you want extended studs from companies like ARP you will either need to re-bore the holes or (I am getting in studs tomorrow that I hope will fit and will update this)
I havent looked around for a OE size stud that might be able to match the 12.6 knurl diameter maybe for some other car, that might take some time, most OE sizes seem to be above 13mm or so
********

I called Dorman to get more info and they are well aware of this issue and dont know why its being manufactured that way.


Here is a pic of IS300 ARP Wheel Studs (14.17mm Knurl Diamter) Next to the Dorman Studs that came out of the wheel hub
These ARP studs WOULD have fit if the hub were the spec it should be.

But they dont have replacement studs. Have to buy a whle thing. Lol. Woow

good info, but breaking a stud is a bit rare unless you overtighten or some other extreme situation. Rockauto sells them pretty cheap as well. you can also decide on using the camry's own if it makes a difference. Nonetheless, something good to know. More info the merrier.

Well yesterday I realized the only way to prevent all this drilling and other nonsense is to get hubs from Toyota (about $130 each) or find a used hub from a junkyard or some car guys. Thats the only way youll be getting the RIGHT knurl spec and not this aftermarket OE nonsense


Yeah stud breaking is very very rare, I guess this whole thing is really more for people that want to run extended lugs on a 5x114.3 setup....which may just be me lol.
