front driveshaft bolt specs?

[neliconcept]

i know they are a 14mm head and i think a 8mm size, but does anyone know length and or thread pitch? well hell thread pitch doesnt matter as long as i know the length so i can get some from ace soon.

dealership wants like 70 for 8 with nuts and washers (one washer per bolt) which im absolutely not paying.

you know that they are pressed in the the t-case side right.

i dont have a stock tcase. i have inchworm with flanges, btw i dont even think stock tcases have pressed bolts, its flange to flange.

Check marlins site, I think they sell them.

i saw it said something about 10mm size bolt through their flanges, i do have my driveshaft off and i guess i could measure it myself..

but didnt see bolts on marlins site.

just need 4wd for this weekend (technically prob could still do the trail in 2lo with rear locker engaged)

well the main thing you want to look out for is the shoulder on the bolt. The main problem you will find with most grade 10.5 bolts that are short enough, is that they will be about 90% threaded. This will cause the bolt to have some play and then they will stretch, leading them to breaking. I went through this with my fj40 after i installed my Orin, i installed grade 10.5 bolts from napa. I broke 2 set before going with OEM, now everything is great.

If you are going to go that route, you need to use a die and cut threads on a longer bolt with a shoulder. Then trim the excess threads to match the original length driveshaft bolts.

Dealer probably have them in stock. I got a whole pile of them at the shop for the early junk like I have. Don't remember what size but if I was guessing I'd say M10x25mmx1.25mm pitch. I do know they are 14mm head size

thanks everybody, i have the oems but i stashed them at my friends shop and i couldnt get to them, so this will be a sort of temporary solution. i get the thing about the shoulder, never can get the right combo of thread and shoulder ratio lol..

thanks all

I know this won't help you right now, but for future reference:
Marlin Driveshaft Bolts (http://www.marlincrawler.com/htm/axles.htm) scroll down to the very bottom of the page. No wonder we couldn't find them, they are on the "axle" page. :laugh:

lol i guess i should have looked harder.

it does say till 95, but those look like the right bolt so i assume they should work for my application as well.

i have to return the bolts that i got from lowes, too big of a head which would not allow box end to fit with the ujoint in the way.
