upgraded axle shafts

[jeeping1974]

I was on http://www.moserengineering.com/ and was looking at their "MAX 60" ( http://www.moserengineering.com/Pages/Axles/max4460.html (http://www.moserengineering.com/Pages/Axles/max4460.html ) axle)) axle shafts and was wondering if anyone here has run these shafts before in their front D60? I'm trying to find out who make a good quality axle shaft that won't break the bank and was thinking about giving these a try for when mine break.

Also, does anyone know if someone out there makes axle shafts for a rear FF D60 out of a 79 j20 with an offset diff or is it something that I'm going to have to have made up?

[Stuka]

You will have to have them made. And I am not sure if they have enough meat to have them bored out to fit 35 spliners or not.

Just get a 14 bolt or D70 and call it good. That will give you much stronger axles at a fraction of the price.

[caionneach]

I have heard several good things about the 14 bolt. Does it match the slightly off center alignment of the differential which the AMC 20 has?

Then new rims, matching gear ratio, fab work, welding, loss of ground clearance if you don't shave it, etc etc. Don't forget to take everything into account.

Still worth it... With a FF D60 in the back, I would have to assume that he already has the 8 lug rims. By fabwork, do you mean welding on new perches? If so, thats hardly a big deal, but if you dont weld, just find one that already matches up. My D70 bolted straight into my Chief, and I would assume that there are 1 ton axles that would bolt into a J-truck too..

The whole point is to have a stonger axle, and there are several ways in which a D70 or 14 bolt is stronger. However, this pic speaks for itself...

My reply was directed at caionneach's post about swapping 14bolt for 20. As far as I know, no 14bolt matches FSJ perches. And yes, he would have a lot of cost to look at, plus cost of going 8lug front.

Ok, well you quoted me, not him. My response, and comments regarding the 8 lug wheels was for the benefit of, and in reference to, the person who started the thread. I tend to ignore the random hi-jack attemtps...

[jeeping1974]

I already have a chevy D60 SRW front axle nd a set of 8 lug wheels, plus I'm going to be installing a set of chevy 64" leaf springs under the frame so I know that I will have to weld on spring perches and shock mounts.

There ya go... Just sell the Jeep D60, and get a 1 ton axle for the rear too... What is the gear ratio in your D60 front?

[Dmntxn77]

BTW, Its not THAT uncommon to find a 14 bolt with 4.56:1 gear and a Detroit for around $500-$600.. Thats probably no more than the Moser shafts would cost you.

[jeeping1974]

The 60 front has 4.10 gears. I'd like to find a 14 bolt with 4.10 gears for the time being and then once I have enough saved up for larger tires (in the 39"-42" tall range), I'm running 35s right now, I would like to change the gear ratio to 5.13.

[Dmntxn77]

It should be pretty easy to find 4.10's... I would guess that that is the second most common gearset next to 3.73's in 1 ton rears...

That is correct.

Ooops I sure did, my bad. :D

[Slick Willie]

I found three 14 bolts with 4.10's with one week of looking around Austin when I was there. All 3 deals fell through, but still. 14 bolts are very easy to work on, simple in parts, and abundant in parts. I took the ring/carrier out, welded the spiders, put them back in without worry. And I can't settup gears or anything, nor had I done it before. And they're beefy.

I might be temped to do the same if I can get my hands onto one and weld the spider gears. I'll be taking the locker that I have in the rear D60 and install it in the front D60 as long as it fits. The front Chevy D60 should be a 30 spline right? I'm going to pull the shafts out anyway when I start to clean it up, but I just wanted to make ask.

Anyone here run those moser shafts though? Slick Willie - how much did you pay for your front shafts, what did the price include and where did you get them from? Moser want $510 for the set and u-joints.

[Slick Willie]

I bought the front outers first, and they were ~$220 after shipping, the front inners just cost me $405 after shipping, then tack on U joints (~$30). That's for 4340 Chrome-Moly inners and outers. Beef

[Stuka]

Front D60 should be 35 spline inners, 30 spline outers.


But a rear D60 wont hold up to 42's in a full size truck without going to 35 spline shafts and probably a truss. Where as a 14FF will handle that stock with no mods.

[4x4fEvEr]

wont a centered rear diff hit his gastank? a 74 has a coffin tank right? if so it will hit. if not ignore everything ive said. id go with the 70. 14 bolts are great too, just more pluses with a 70. bigger ring gear, nodular case, 35 spline shafts, only a half inch ground clearance loss compared to d60.

I've had a set for a couple of years now in my ProRock front w/Longfield super joints and 35spl outers in my Unlimited. I beat on it pretty had and haven't had any problems with them and all. Of course my little jeep doesn't weigh as much as a FSJ so I'll find out when I finish my Gladiator.

[Dmntxn77]

Yes

a 74 has a coffin tank right?

Yes

However, with a shackle flip and 63" Chevy springs, he should be ok.. I am pulling in the coffin tank in favor of the the rear aux tank only, as to avoid ALL the bad that comes from the factory tank...

I agree.. I went with a 35 spine D70...

I hadnt realized the ground clearance being that close to that of a 60.. However, I have noticed that at least a 1/2" if not more can be shaved off a D70 pretty easy... That is on my list of "someday" mods. I am more focused on just getting it on the trail first though...

[jeeping1974]

Yes a center diff would cause problems with the stock gas tank, but I have a 22 gallon fuel cell mounted in the bed, so I'm all set there.

On a local wheeling forum, shaved axles came up and a shaved 14 bolt can net you more clearance than a shaved D60. I don't know how, I have never done it. I'll try to find the thread and post the link. hopefully you don't have to be a member to the forum to be able to read the thread.

[jeeping1974]

Thanks Stuka. I'm going to double check that cuz then I won't be able to use the locker out of my rear D60 that I have now.

really? i would have thought it to hit for sure. when i went from the stock offset 44 to an offset d60 i had to trim on the gastank skidplate for mine to work, best option is to ditch that tank anyways.

yeah u can get that 1/2 inch off the 70 easily. i had a ford 60 so i just went with 35 spline chromo shafts and a spool :thumbsup:

He has a long wheelbase J10 though. The tank isnt close to the axle like it is in a wag. Hell my stock rear axle would hit the tank with 6" of lift on my cherokee when I flexed it enough.

They had to shave the crap out of that 14B to get THAT far. There's alot of iron in their bellies, but not quite that much. 3/4" inch shave is easy (other than elbow grease), 1" shave take a little modding the diff cover, but GM was generous with the iron in a 14B pumpkin.

Shows a lot of pictures of shaved axles.
The 14b can be really cut up!

I know my 70HD has a lot of material I need to take off. But I am not going as far as these guys did. I still want most of the strength of the axle housing.

In the 14 bolt Bible, scroll down and there's another 14 bolt shave:http://www.pirate4x4.com/tech/billavista/14b_bible/index.html
