This might help those doing a Solid axle swap. Came across this while doing some research on fiberglass fender

 

 

 

 

 

 

 

Subjective Axle Strength

Dana 35 ifs 33in wheel bearings, outer axle failure

Dana 44 36in early small axles break, floater kits break axles if housing isn't straight when installed

Dana 44 ifs 33in R&P weak, hubs and half shafts

Dana 60 44in in pickups carrier bearings fail

GM10 Bolt 33in carriers break, tubes bend, weak axles, spider gears, outer wheel bearings

GM 12 Bolt 36in tubes bend, pinion bearings wear, spider gears, wheel bearings, axles

GM 14 Bolt 10.5" 44in Gov-loks fail

Ford 8.8 33in stock axles, spider gears

Ford 9 in 38in Early 28 spline axles weak

Ford 10.25in 44in similar in strength to Dana 70 and 14 Bolt Full Floater

we should pin this along with some other links and locate all the information that people are looking to do a sas project that way people can easily locate it

[88pathoffroad]

There's not really that much debate on what axle to use for an SAS. If you go the easy route and don't change t-case and trans, you get a driver's drop D44. Plenty strong enough with a few upgrades. Lots of people have them. Good axle choice for a budget build, which is what most people want.

 

If you want something else, you'll pretty much have to change transmission, t-case and go with a different front axle. Expensive and you'll pretty much have to engineer everything yourself...steering, driveshaft, etc...

[Guest SuperSon]

Doing SAS is a waste of money IMO but some people like it.I have not seen one pathy that is sas'd and doind some serious rock crawling.Why in the heck even do an SAS?but hey its their rig and moneyI dont think mudding and occasional pebble crawling calls for some SAS.

 

Id rather spend my money and make my truck look like this

[88pathoffroad]

Dude, you have to be kidding me. You've never seen a SAS'ed Pathy rock crawling or doing hard trails?

 

Check the Pics and Vids section again, there's some good ones out there.

[Guest SuperSon]

Nope.Seriously. I gotta do some more exploration on this site

Edited April 22, 2007 by SuperSon

[sammyb33]

yes please, look around, the people who go thru the work of doing a swap USE THAT AXLE.....

[Guest SuperSon]

Searching.

One could argue that building your truck to "look" like the ones in the pics you attached would be a waste of money as well, unless you have a real need for it by actually using it for the intended purpose.

[Extreme90path]

SASed pathies are pretty damn sweet. But I have to say that I will probibly never do an SAS on my pathy. SA up front is awesome for rocks. But really every where else IFS rules....or at least I think.

I read this and laughed out loud and i'm all by myself.

 

No real rock crawling eh?

 

 

 

 

 

 

Ok, i'll stop.. get the idea.. oh ya, 90% nissan. Only the axles and suspension are not Nissan.

Stock engine, stock tranny and 3.7:1 T case gears in a stock T case.

[87pathy]

oh and those pics...

 

Those are in iceland I promise you. They build those rigs to float on the snow. Low horse power and lots of flotation.

Generally built with 4-6 inch body lifts and no other upgrades except tires. They are only good for deep snow, nothing else.

 

Don't get me wrong, iceland has some bad as rigs! but i know the type in the picture

[Guest SuperSon]

nice first ive seen.

 

 

 

Those icelandic pathy sure are badass.Heres one that should be able to climb the gibraltar and mt.everest and it is street legal

 

Edited April 24, 2007 by SuperSon

[88pathoffroad]

4-6" is a conservative estimate on the body lifts, man. I think I recall seeing 12" lifts being used.

[tmorgan4]

Maybe it's just me, but I think I see a solid axle on the blue Patrol.

patrols came with solid axles.

[Mookie]

nice first ive seen.

 

And there are tons more out there. Along with this site, check out the AZ and the CO boys sites to start. I'm assuming from your comments regarding Sas'd Nissans you haven't done much wheeling? Technical trails?

 

[ShadowManR6]

what's the rear axle that come in an 87 pathy?

hmmm, sombody went away.. thats funny. Did some research did ya?

[Guest SuperSon]

Still doing some

 

oh yeah that beast has chevy axles according to their site and darn it forgot to save it

with those size tires no need for a lot of uptravel

hahaha itd be like wheelin an ifs/irs in the rocks though
