Front Axle Hub Bolt Help

Hi everyone.

I am close to getting my CJ back on the road, and an earlier post on this site identified my front axle as a Dana 27.

The CJ came with no front hubs, so i ordered some online, but i dont have any bolts to bolt them onto the front axle.

Here are photos of what i have at the moment

I need to know exactly what kind of bolt to get for these 6 bolt 10 spline hubs.
I can't get bolts here, EVERYTHING is metric.
if i NEED a bolt for an engine or transmission, sometimes it take a month or so to find one bolt and it can cost $10 or $20 for ONE 50yr old bolt to put the head back on.
Most of the jeep has metric bolts smashed into it, but i dont feel like drilling and tapping 24 good holes just to go metric grade 1 bolts

If i was back home, i would just go to the store and buy handfulls of random bolts and see what fits and put the rest in my "extra bolts" bin.
but i cant do that, i have to order them online and with shipping and everything i need to know the exact length, size, type, thread, ect

Any help would be appreciated

Can't tell if you have any response, but on the D30 they are 3/8 coarse thread.

What year is your CJ?

3/8 is right, the length will depend on which style hub you get.

Your profile says you have a CJ7, what year?

The dana 27 was not used in CJ7's (before their time and used between 1961-1971 in CJ5's, 6's, CJ3b's), so you or someone swapped it in? As far as I know all CJ7's came with the Dana 30, which is a better axle than the Dana 27.

It is either a 25 or a 27 (closed knuckle). I see early brakes which would denote a mid 60's and earlier M38A1, although (oddly enough) the shackles in the front.
you should be able to get bolts from the company that is shipping you the hubs.
Your other option is to do a through once over, make a list, then simply pick a company stateside you can work with and put in an order. This could include a "bag 'o bolts". Most Jeep specific company's should be glad to help you with the selection.

PS, don't forget to get into the front knuckles and get them serviced. I would do this prior to any further orders, since you run the real risk of bad kingpin bearings and knuckle seals.

Mine has studs in that position. It was a bit of a pain to find a replacement here, coarse on one side fine on the other.

You can't be the only one with this problem. Might be a money making opportunity to sell SAE bolts. How do you ship over there? How much would 20 pounds cost?

I have 2 CJs i didnt know anything about CJs when i bought them.

I thought the one was a CJ7 based on its wheelbase and squareish door openings, but everything here was made before 1975 so it cant be a CJ7, i'm pretty sure someone just stretched a CJ5 based on the bodywork i can see after i stripped the paint off.

So i have a stretched CJ5 and a CJ6
Both with a 4 cylinder engine, and the same front axle. but they have different transmissions and transfer cases.

Ok, I stuck a smaller bolt in the hole, just to see how deep it was, and so i will order some 3/8" coarse thread bolts 1-3/4" long.
i might order some 2" long also just in case.

grade 8 i assume?

Thanks for the help

Did you order new hubs? If so, that should be about right. If you bought used hubs, some of the older style hubs take much longer bolts...

Yes, i ordered new hubs, these ones:

http://http://www.morris4x4center.co...pline-481.html

Shipping will take about 3 or 4 months.


Underneath the dirt it does have a "27" cast into the housing, good spotting that.

Even if the gears dont match, there isnt much i can do about it. everything is 50 years old and there are no replacements available.
If anything breaks i will have to remove the entire assembly and replace it with a russian axle set.

There isnt much hard core wheeling here, just some dirt and mud roads and some monsoons. i just have to wheel gently

Do yourself a favor and determine if the gears match.

Mismatched gears will mean no 4wd, especially if you engage it and blow the transfer case apart.... Verify the gears. Pull the cover and count the teeth.
