Separating and reassembling the birfield and inner axle assemblies

I have a question that I think might be dumb but I am going to ask anyway. Why would the trunion shims cause the ABS sensor not to work Properly?

Thanks for all you help. All your inputs have been greatly appreciated. I am really enjoying learning about all this.

The way I view it - the shim is set by the factory to keep the trunion bearing at the right preload. Disturbing the shim you are effectively changing the torque of the preload. I honestly don't know whether it affects the ABS. I just brought up a couple of common things mentioned in the FAQ. Good luck.

I should have been more clear, I was asking about the trunions, but seeing I haven't done either of these steps in the past, it's all good.

WXM You are probably correct. I was looking at another ABS thread and it also pointed to the trunion shims. Does anyone here know why the trunion shims would affect the ABS?

I broke a Birf in Moab and replaced with a spare worn birf. When I got home I had to install a new Birf and I had never installed a birf before to the axle. That dang C- Clip was giving me problems and thanks to Mud I found an answer using a clamp as described in this thread. It worked great after trying everything I could think of for longer than I care to mention

I edited the Front Axle FAQ thread post #14 to include this

1.5" inner diameter ABS

vs.

2.5 to 3.0 inch diameter PVC

Any consensus in the years since these posts as to the ideal pipe diameter, and whether there's a difference between ABS and PVC for material?

I don't think there is a right or wrong answer to this but I personally prefer the larger Inner Diameter plastic pipe ( ABS vs. PVC doesn't matter much; you are just trying to prevent marring up or messing up the birf) because it helps to hold the birf assembly square to the floor whereas with the smaller ID stuff it is somewhat more "sloppy". Again, this isn't a right or wrong answer to this, just a personal preference.

Ohh, I guess one advantage of PVC over ABS is it is easier to see the grease that gets everywhere; with ABS (black or grey) it would be a bit harder to clean.

Does anyone know how to access the photos in the first two posts of this thread?
Thanks...

I would like to see the photos too!

Is anyone else having an issue seeing the images in the first post? Or is it just me?

 

[LFD2037]

It appears the descriptive pic's have been deleted but this thread would be even more awesome w/them!!!

 

[dioscw]

I can't see the photos, It's just me or the links are broken?

@Driley looks like the pics are gone, any chance you can reupload? Thanks!

All photos are still showing here Getting ready for front axle rebuild... finally

Last couple of pages of the above thread have the photos.

I can repost them or just email/text if needed. Send me a PM if needed.

I am FINALLY getting around to swapping sides for the birfs. I put them together in accordance with the first post in this thread. Flat edge of the ring facing down into the cone, side of the star with the c clip groove facing down into the star. Seemed difficult putting all the balls back in. Hit the shaft in and locked in place. BUT for some reason it can barely move. I remember when I took them out I could have the shaft and birfield at like a 120 degree angle, but now it barely moves at all. The birfield locks up. I used the right grease, I put it back together how this thread says too, but something is not right.

help!!

Well I looked at the pictures on this post:

Looks like I have the star upside down. I got confused, thinking the "tapered area" was where the c-clip goes.

I will flip the star over and try that. Carry on... sorry to bug you all Please pray for me before I push this thing off the side of a cliff. REALLY ready to be done with this ridiculous job.

It's been a few years but I believe the star needs to have the larger cut out facing out of the cup/tulip than in. I will find a picture to show what I am saying.

 

[Driley]

See the cage and star out of the cup/tulip.
