OK, so I have Warn hubs (which are tightened) on the ends of my Newfields, so I've gathered I need the bolt/fenderwasher combo...

Currently, there is nothing in there, which made the hub removal nice and easy, but I'm worried about the birf moving around in the knuckle...

So, my question is what size bolt & washer do I need? I don't have a spare birf to take down to get the bolt right..

Thanks guys..

And is it the general consensus that with a Longfield & stronger shafts, keeping my Warn's might be good as a cheap, easy trail fix? if so, I might not look for Aisin's quite as much as I have been...

Probably just a :rainbow: newbie question, but I really couldn't find the answer (referring to the bolt&washer size, not the warn vs. aisin one)... Once again, I'm ready to be pimp-slapped if this info is readily available...

I think the bolt size is 8mmx1.25 I would get about a 15mm long bolt and corresponding fender washer. I have seen Warn kits that had them in it, so you might ask around maybe someone did not throw them away... Might try a dab of red locktite too.

I used a washer that was 1 3/8" OD and a standard metric bolt for a 12mm socket (don't know the DIA but the pitch was 1.25) about an inch long.

Just had a talk with the Texican and he said that he knows people who do not use anything on the end of there birfs at all.
I guess as long as you use stock birfs its ok but with a Long field you need to use a snapring or washer assy, the added ring welded to the bell will drag in the knuckle housing.

Thanks guys.. I just picked up 2 8mm x 16 bolts, and 2 fender washers, I'll measure the OD tonight.. hope it's right!

Newfields also have the added ring on the bell, so that's why I'm going to run it.

We've discussed this in the past, but I'll reiterate my opinion...

IMO, the snap ring or the bolt/fender washer are necessary.

Bobby Long requires them....why? Cause they prevent the birf from floating inwards of the spindle. In his case, allowing them to float in would allow the welded ring on the birf to potentially contact the inner axle shaft at full steering lock.

Newfields, with their as-cast design, would have the same problem....the bell is deeper on these, much like the Longfield.

Stock birfields would not have this problem.... however....

Allowing the birfield to float in-out, even that little bit, changes the angularity of the inner axle shaft, and may effect the amount of spline contact and may effect the direction the torque is applied thru the birfield. Minor? yes. Is it enuf to perhaps create additional side forces on the inner shaft and on the birfield and increase the chances of blowing a birf? Also very possible.

You decide....
