spindle bolts?

[thepinktaco]

Im putting my axle together that Ive pieced up. I was looking at the store for spindle bolts. I know that they are M10x1.25 but the heads on these bolts are huge, I think 17 mm. Will having a 17mm head interfear with anything? Doesnt look like it will but I just want to double check before I drop money on 16 bolts.

And does anyone know why bolts you buy in the store the heads are bigger than the factory ones?

I beleive those bolt heads set in a steel channel of one of the dust seals, so large heads will either not fit or the 17mm socket for them wont fit,

those bolts hold the truck up, the factory bolts are not just standard grade, as proven in many 80 series accidents the factory bolts are strong enough to bend the axle housing, I wish i could remember and tell you what grade they were,

If you need new ones, I would buy them from Toyota. I'm sure they are a high grade bolt, and they are the same ones used since the early days of Land Cruisers, at least my 76 has the exact same bolts. I would not use other than stock bolts.

If you look carefully at the assembly, the real strength is in the cast lip of the spindle-it fits very tightly inside the opening of the knuckle, the bolts just serve to keep in in place.

I would only be buying grade 8 anyways so I dont think strength is an issue.

Maybe not, but why not use what is known to work and fits? At most you might save $5. I would only use stock in this critical application. What are you trying to accomplish by using non-stock bolts? Not trying to be argumentative, but I think you are headed the wrong direction here.

If time is your issue, Cruiserdan can have those bolts in your hand in 24 hours, and the'll be the right ones and fit perfectly.

BTW-the heads of the bolts are different sizes, because Toyota and other Japanese companies use "Japanese Industrial Standard-Automotive" sizes. The rest of the world uses a different standard, and one that specifies 17mm heads on 10mm bolts. JIS-Automotive specifies 14mm heads on 10mm bolts and 17mm heads on 12mm bolts.
