I know that a solid axle flexes WAY better, and I've been thinking of selling my '92 IFS'er to get and solid axle Toyota, but am concerned with the birfield joints. Are the birfield joints stronger than IFS? This may sound like a strange question, but whicheverI keep I would like to get some 35's under, and it seems people break birfields close to as much as people breaking IFS components. I'd much rather replace an idler arm or cv shaft on the trail than a birfield, so I was thinking of keeping my IFS. Thx for your opinions, don't yell at me too much! <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

dude....I ma way happier with my IFS....pound for pound with open diffs it will blow away the IFS all day on trail...havent had any problem with birfields and it has been wheeled hard, but I only have 33's so.....
there have been times where I have had tire traction on the ground and the most of the fender and the gas pedal mashed ot the floor and they survived.
Ive seen them survive abuse from an ARB, 108:1 and 35 in. beadlocked MTR's...They are strong if you learn how to drive and dont do stupid shit

im konfuuused; what are you happy with? What have you seen survive an ARB, and what survived with your gas pedal mashed to the floor? <IMG SRC="smilies/confused.gif" border="0">

I dont think the birfields are really weak, theyre just the most likely to break out of all the parts in the frontend, I've never broken one, I'm sure I will though, so i carry spares, but i wouldnt worry about, I used to know a guy that ran 38's with a welded front diff, and only broke one

If your toy is in good shape, SAS it instead of buying an 85.
birfields can hold 35s pretty good,
or if you are worried you can go all out with fullwidth big ass axles.

Have you ever compared the physical size of the 26 spline IFS axles with the 30 solids? Big tires, low gears, and tight turns break Birfields. I'm sure I could build a rig that would snap 60's, but what would that prove, that 60's are weak? Don't think so. You use the axles to match your weight, power, and driving style.

I don't think an IFS will never be as strong as a solid axle, because you have two joints per side, that is two weak links. It in my opinion will also never outperform a solid on the rocks, because no matter how much travel you can build into an IFS you never have the leverage factors that a solid axle has (I.E. one tire goes up on a rock the other drops down as a result). Also when you compress the IFS suspension the crossmember gets closer to the ground.

My view has always been this

Solid axle=rockcrawling or other slow travel dependent wheeling

IFS=Pre running and racing

These are of course just opinions and although they are my opinions and I am obviously very innate <IMG SRC="smilies/laughing.gif" border="0">, they are subjective nonetheless....

More then likely every other week until all the Birfields in the world are gone, in other words forever!!!!!!

Birfields are weak!!!! Dana 44 Joints are not that much stronger. Fix it right go with a D-60 or a Currie 9. Or watch your wheel placement, run with your front locker off (ARB or Toyota eletric) Upgrade your Toyota axles with Redline (Randy's R&P), Marfields, CV Unlimted, D44 or D-60 Hybred from All Pro/ Currie. Learn how to change Birfields and quit worrying about them and enjoy yourself. If all you think about when you are wheeling is breaking something, find another sport. <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

Just keep in mind - out of the box, Toy solid axles don't flex for CRAP. Som comparing apples to apples, in stock form I say they are about even...

Geeez, I never SAID I was worried about it, and I'm not. Truth is, it doesn't worry me in the least. I am currently in the process of buying an '85 solid axle pickup, and wanted to post this question in the meantime, out of pure curiosity. Holy crap, you guys are jumpy! <IMG SRC="smilies/thefinger.gif" border="0">
