Kirby N.'s Navajo Solid Axle Swap

[Kirby N.]

Haven't worked on the truck much. My buddies keep breaking thier Jeeps and I end up helping them work on the stupid things. My brother spun an axle tube in his rear Dana 35 so we are going to truss it and beef it up. Then my friend broke an axle shaft in his rear dana 35, so I sold him my 8.8

That forces me to build myself another Rearend I picked up an EB 9 inch last night. Not real familiar with these axles, but I am going to get that way. It has 28 splines and 4.11s. I am going to put some 4.56s in it as soon as I can. I really wish I could justify some 31 spline axles too- that might have to wait until I gernade a 28 spline. Anybody know if a 1310 yoke can be had for the 9"?

I have seen the 1310 yokes on ebay, But I am putting a full width 9 from a 78 f-150 in my explorer right now, and for $78 I got slip yoke that was 1 1/2" longer than the explorer yoke and 2 new u-joints the front is a 1310 and the rear is a 1310/1330 u-joint which is what the f-150 came with fromt the factory, so I got my driveshaft the right length and new u-joints for less than the labor of having the driveshaft retube/lengthed.
If you want I can get you the part numbers.

If i were you when it came time to upgrade the 9" i'd pop for the 35 spline carrier/axleshafts and be done with it. You'd be real close to a D60 in strength plus the bling factor is always cool
I'd give Randy's ring and pinion or Currie a call on the yoke, they would know yay or nay on that subject more than anyone.

Definitely agree with that. I am probably going to leave my FW 9"(already 31 spline) mostly stock for a little bit so that my wallet can attempt to recover after this swap. When I get the money though(and find a good deal on ebay) I am planning on getting a 35 spline third member, axles, etc. and have a 35 spline Ford 9" like DB_1 said. The 31 spline should be fine though, even with the 37s I'll be running. Good luck

Change of plans Sold the Axle this morning. Got the $200 out of it I paid for it I got to measuring and I decided it was a stupid swap. My 8.8 is almost as strong, it is the same width and it already is in my truck. I am thinking I am going to either cut down a FW 9" with 31 splines or get a disk brake 8.8 with 31 splines. Much easier. Thanks for the help!

get a 76-77 EB 9" then upgrade to 31 spline shafts. much easyer then narrowing and drop in a 3rd from a fullsize bronco that already has 31 spline boom narrowed nine. im going to be running a EB 76 9" with full spool and 31 spline axles. WMS of about 59"

 

[redranger4.0]

make sure you get a big bearing though

 

[Kirby N.]

Nope. WMS to WMS is 78.5. I had one ealier. That is why I got rid of it mine. It was a 73 or something. I think a Explorer 8.8 with 31 splines and disks is alot more worth while swap. Your 76 might not have BB. a 28 spline 9" really isn't much stronger than your stock8.8

i have my 9" already and its 31 spline big bearing(used to be 28 spline) and its the same width as the explorer axle

im talking EB not fullsize bronco.

 

[Kirby N.]

Oh, sorry I meant 58.5. You are right exactly the same width as an explorer 8.8. That is why I am going to just try to find a Disk Brake 8.8 with 31 splines. If only the bolt pattern was right...

Oh well I think changing bolt pattern will be less hassle than narrowing a FS 9" or making an EB 31 spline and bolting on some disks...

BUMP!

I had some recent questions on my SAS and noticed my writeup had lapsed leaving it not up to date and the links for the pictures were dead. So fixed them in the first post and added some new ones for your enjoyment! I think it is up to date now.
