Birfield vs Dana 35 u-joint....pics inside.

[-Nathan-]

Long story short, I actually do a fair amount of work on Toyotas as well, as my buddy is into them. There was a slight argument in the non-ranger axles section, and figured Id post these pics I took the other night. These are of a Dana 35 u joint next to a Toyota birfield. For those of you that don't know, they are the 'cv' portion of a Toy axle, in place of a u-joint.

Pics arent great sorry,

For good measure, and just in case anyone was wondering, I figured I might as well post of pic of his truck. 1990 v6 toyota, dual t-cases, 5.29:1 gears, dual detroits, 37 iroks.

makes for a decent wheeling buddy......even if it is a 'yota

To be totally honest, a Toyota would be about the only other small pickup I'd entertain building to wheel.

So what are you saying, that the toy Birfield is stronger, as strong, or not as strong?
I'm not familiar with c.v. or Birfield joints, can you give an explanation of how they work, or a link to?
Thanks,
Richard

Basically, a CV joint as you can see in the above pictures, has a whole pile of bearings in it. This gives it the ability to be spinning faster and at a more extreme angle for a longer period of time without tendency to bind. Rather than just having four sides, the CV has basically unlimited range of motion and is able to be subjected to constant movement, hence the name 'constant velocity' joint. That's why FWD and AWD cars use CV's up front, you don't hardly ever have to replace a CV.

What you really need to do is relate contact area and radius in order to compare the joints.

Simply comparing the size of a standard cardan joint and a Birfield joint is like comparing a Bulldog to a Parakeet.

yep, cute CV joints. Is that an early Jeep truck in the first pic?
