Swap Drive Flange Studs to Bolts?

[akarilo]

I've heard of swapping out the drive flange studs with 8x1.25 bolts. It would obviously make axle disassembly a hell of a lot easier. With the cone and lock washer in place, I really don't see an issue with strength. Has anybody tried this with success?

I did research a bunch of old threads but didn't find any definitive info.

It would work, but wont be as strong as studs.

I want to do this to the rear with 10mm bolts

I'm not seeing how this would be beneficial at all. I don't have any problems disassembling the front end because of the properly assembled cone washers/studs.

If you swap out the studs for bolts, it WILL be weaker, and you will be damaging the bolt/drive flange every time you remove them. When you loosen the bolt w/cone washer, one of two things wil happen, the bolt will spin inside the cone washer, thus damaging the threads and making it weaker every time. Or, the cone washers will spin in the drive flange, thus galling the drive flange and preventing the cone from seating properly the next time around.

If ur having trouble removing the cone washers, remeber a couple things, they don't need to be torqued extremely tight and all it takes to remove a properly seated cone washer is a little tap on the end of the stud. I back all 6 nuts off to the end of the stud, put a short well socket w/extension over the nut and gently tap a couple times, the cone washer will unseat and you can then pull them off by hand.

If that method isn't working, then you have bad studs or cone washers, or some retard PO put permanent Loctite on them, which I have had happen to me

This all sounds logical. Good talk.

the PO of my cruiser did SOMETHING to the studs, or washers, or something. i ended up cutting 3 or 4 of the studs off, and i ruined 3 cone washers in the process. i am still trying to locate new cone washers (haven't looked very hard yet), and am most likely getting new studs from the dealer. mine we're so screwed up. i like the theory that the studs work better and are easy enough to disassemble when assembled CORRECTLY, its when they aren't that replacing them with bolts sounds like a better alternative

Yeah, I've had those kind of troubles before, definitely frustrating. I remember the first time when I was a kid, I replaced the Aisin's with Warn hubs cause they didn't use cone washers, I'll never make that mistake again.

If you are still looking for cone washers, PM me and I can send you some extras I have around.

Toyota does have them if you want new ones though, 42323-60010 - OEM Toyota WASHER, CONE
and the studs, 90116-08325 - OEM Toyota BOLT, STUD

If you have access to air, use an air chisel with a blunt tip and hit in on the drive flange on either side of the cone, it will pop them loose every time, even a regular hammer and a brass drift will work (just not as well/quickly).

But I agree, the studs are stronger, and if properly installed, just as easy to remove as bolts...

Agree, the vibration from an air hammer knocks them right out, all of them in seconds. One of the main reason that I carry air tools on the trail.

Yotaonly, thanks for the offer! Im gonna grab them when I get the studs/nut from the dealer and replace them all I think. The ones I didn't cut, were bent or otherwise in crappy shape so I am going to go new with everything and hope I never have to do it again.
But thanks for the part number! I looked briefly and didn't find it.

I'll have to remember the air hammer trick of I do it again. Thanks !
