Why is it you dont hear about people using these very often, like the Dana 44's and such?

 

Because this is yotatech lol

Go here: pirate4x4.com

You'll find real tech and lots of info on full widths over there.

 

Interesting...

part 2 of question: Why dont more people on here use full length?

 

Because 90% of the people on here don't even know what a full width axle is, and have no use for one because they drive on dirt roads and call it 4wheeling.

What are you wanting to know about full widths?

 

Here's a thread to get you started.

jeez 89silverpu.....generalizing a bit toooo much there..

most people don't go with full widths because of the wheeling they do, the stock toyota axle (with upgraded shafts and such) is plenty strong enough.

most people that SAS their trucks still drive them on the highway occasionally, so full widths would be too wide...there tires would be stickin past their fenders like 1ft on each side LOL

 

Just wanted to knwo about them in general... pro's cons etc.

 

Not to mention some places are so narrow it'd be more difficult with a wider axle.

 

Just a few pros and cons

Pro's:

-Far superior in strength than a Yota axle
-Can handle bigger tires (Yota axles can only realistically stand up to a 40" tire)
-Give a wider stance which is more stable in off camber situations

Cons:

-The extra width can make skinnier trails more difficult to squeeze through
-Way less ground clearance than Toy axles unless the axle is shaved or is on a 42"+ tire, I think the equivalence is like a 37" Toy axle is the same as a D60 on 42's (not 100% on that but you get the idea)
-Toy axles have removable thirds which make trail repairs easier.

It depends on what you want to do. Unless you want a rig with above 40" tires I'd stick with the yota axle, it wouldn't be worth it otherwise with a properly built Yota axle.

 

Ah ok. awesome. thanks.

 

Agreed. Optimal tire size for Yotas is a 37" IMO.

With full widths you also must upgrade other things to handle the weight, like the engine, then the rest of the drivetrain, then everything else to accomodate the HP. It is a snowball effect.

If you want to upgrade your toyota axles look into a HD Toyota housing like a Rock Assault or a Diamond or FJ80 axles.

 

Dana 44 is weaker than yota axles, unless they are built.

Ground clearance was mentioned, especially with 14 bolt in rear. and D60 infront. It is the perferred setup I'm seeing now. (Don't have a table to prove this at the moment, don't have time to search right now)

With the Longfields the Toy front is as strong as a D60 with 35 splines and stronger than the D60 with 30splines. http://www.longfieldsuperaxles.com/p...etestgraph.jpg

So really unless you get a steal of a deal, its not worth it in my opinion.

Landcruiser axles have become popular too.

 

Lots of little gotchas with the full width axles as well, none are insurmountable but must all be dealt with. Things like 5 or 8 bolt patterns on the wheels, then brakes (metric to SAE adapters needed), then drive shaft to differential connection, need for custom steering bits (average SAS kit won't work), spring perch spacing/centering (may need to recenter the axle or shorten a side, or relocate spring perches, etc.), gear ratio matching (if mixing Toyota and Dana axles), etc. Note, you can get custom built, wider than stock Toyota axles made from a number of suppliers.

 

u guys are forgetting 1 major factor, ring and pinyon on a d60 is way stronger than an 8" yota axle. ive got a set of built yota axles on my 85excab, and i kill 2 sets a yr.
im betting i dont kill any ring/pinyons on the d60/eaton 10.5 on my 86 turbo truck on 42"s

 

Depends again on wheeling environment. Ftoys at WEROCK go all day long on Yota axles and 37s just fine. If you gotta have bigger tires, then you should go bigger axles, but I prefer Toyotas.

 

thats not true, my friend has a 4 seater f-toy and at reno rocks this yr, he blew up a brand new yukon 5.29 3rd, trail gear let him borrow thier spare, and gernaded that one too, 37" bfg crawler stickies are hard on 3rds.

 

Yes it is true.

 

A lot depends on set up. example: most say 5.70 is not for wheeling but ZUK has had success setting them up for offroading.

But if you put enough HP and torque and wheel by throttle you are going to break any axle. This is why some guys have no choose but to run Rockwells. Somehow I think a comp Ftoy is going to see a little more abuse than I'll ever do to my rig.

 

rockwells suck, have to lift the crap outta your rig to clear the diffs, and need 47-49" tires for any clearence, takes all of the chalenge out of it.

 

Not totally true about the engine, my cousin has an 86 4Runner with Dana 60`s front and rear with 39'' tires and duel cases, his 22RE is bone stock and he has no trouble at all going down the road at the speed limit or better.
