Blew a beefed birfield...

I was out wheelin' at my Dad's, and I had the suspension twisted up real good in this gully. As a result of this my left-front tire was stuffed up in my wheel well, and the lugs on my 33's were catchin' on the body pretty bad when...BANG! And I was suddenly a 3WD vehicle.

After that loud snapping sound, I figured I snapped my axle shaft, but ripping it down has shown that I blew out the birfield joint. This is rather dissappointing as I just installed some Breeze Ind. birfield rings no more than a month ago! Inspecting the joint shows fractures on the inner edge of the joint, not on the outer area where the ring sits. As you look at the joint, you can see the bearings out of those holes? Well, that's where the cracks are. Damn.

Well, this means more mods to keep history from repeating itself. I'm choppin' the tar outta my fenders and sliding my axle forward as much as I can. While I'm at it, I'll extend my frame and throw in some YJ springs (if I can just find a set!). I just bought a whole front clip from billtooley, and I will do the fender mods to it and install it on the zook when I'm done...I'll document the whole thing if anyone's interested...

I would think that the birfield rings just buy you some time before the birfield
wears out and gernades on the trail. Just my $.02

Re: Blew a beefed birfield...

Hey, I just got back from an off-road shop. They quoted me $60 to take the ring off of my old birfield and press it on the new. 60 freakin' bucks! I told them that was a bit steep and I would do it myself in less than ten minutes if I only had access to a press. So I left and bought me a little 1-ton press. It's perfect for my needs and I can use it all over that zook. It only cost $37, just over half the quoted 60 (punks!). The draw back tho is that I won't have an excuse to drive out to BFE to see my buddy Mike Shannon. SO, you're gonna have to come over to my place! Whatcha doin' Sunday?

Hey P,
Also sent ya this over the topica list...

> ...my left-front tire was stuffed up in my wheel well, and the lugs on my 33's were catchin' on the body pretty bad when...BANG! And I was suddenly a 3WD vehicle.

Tires into the body is a very common way to break the birfields...

Inspecting the joint shows fractures on the inner edge of the joint, not on the outer area where the ring sits. As you look at the joint, you can see the bearings out of those holes? Well, that's where the cracks are. Damn.

This is also becoming common with rigs that are running "rings" of any brand, and not exclusivley caused by tire into body. I run "rings" and broke the guts out of one at the zukimelt, I was only running 32" tires. I know
of at least 2 others that were there that did the same thing. One of those was even a Trail Tough, double tough birfield that spun the splines out of the inside of the birfield. I also spoke to a few other folks that have had
the same failure...

Time to go back to smaller tires or bigger axles....

Re: Blew a beefed birfield...

I was talking to Spidertrax about a week ago and they said they are thinking about some kind of "birfield eliminator" kit. Maybe something like D44 ends on the Zuk axle????

Just thought you would like to know,
Later,

Re: Blew a beefed birfield...

I would like to know about a birfield eliminator. But I wonder about the cost. If it's too expensive, then I would rather just bite the bullet and upgrade to dana 44's...For around $250 you can get a lot more for the buck...

Re: Blew a beefed birfield...

Yup yup, I figgered for the trouble, I'll find someone with a parting ScouttII and grab me some 44's. I like the idea of being able to fall off a 700' drop and at least having the axles survive. The wider footing will be nicer too.
