iim pretty sure he means the a-arm becuase i have the same quad and that is what he is talking about.

 

Go here: Then look at number 13, the knuckle which is part of number 12 the knuckle assembly. The number 13 part is a cast metal peice, very herky stuff. If you look at the pic you can see the casting part that faces aft flattens and has a hole in it. This is where the outboard end of the tie rod attaches too. The tie rod is part number 28 in the follow:

If you are talking about something different then you need to be specific about what you are talking about. Just go to:

Choose the year you are dealing with, then go to 250 and then go to either the "front suspension" section or the "steering" section to find the part you are looking for. If it is a suspension part, then it will in the front suspension section.

 

Bear,

Once again, thanks.

Maybe the piece I'm talking about is the rear part of the "Knuckle, Steering - Right".

In the diagram though, it looks to have a triangular shape to it whereas the part I was told about is "flat, rectangular piece with a hole in one end for the ball joint to mount up to".

I'll have to call tomorrow and find out what model year it is.

What about this diagram:

Don't need to look at that diagram of a 2001 AC250. I own one and know it very, very well. There is no flat metal piece in the steer assembly or the suspension. I have had it apart just this last week replacing the wheel bearing.

 

You have a 4x2...could a 4x4 be different?

 

No, same suspension, same steering. They use a stub shaft in place of the axles from the differential. Its number 26 in the suspension parts pic, I think. Everything else is the same.

 

Bear,

Have you heard of any problems with the number 13 cast metal piece?

What do you mean by "herky" stuff?

What can they do to fix this problem?

 

This part is a casting, where there is a mold (like for jello) and then they melt the metal and when it is liquid they pour it in the mold. When it cools they pop the piece out of the mold and then you have the base part. The the holes are drilled, surfaces machined and you have a fairly heavy part that is strong. I have never heard of any problems with these other than a bearing getting water in it and seizing, causing the bearing race to spin in the machined surface. You will break every other piece in the steering and suspension before you break the knuckle. If it is bad you replace it. I guess if you took an hammer to it you could break one of the ears off, but you would need a big hammer and be strong to do it. The knuckle is not steel, it is iron. The tie rod end bolts directly to the ear that sticks out toward ther rear, that is part of the iron knuckle. No steel plates are involved. "Herky" means heavy and strong, you wouldn't want to drop this thing on your foot. It would cause great pain and just might break your foot.

 

Once again Bear, thank you for taking the time to help me out here.

Ok, using your (the correct) terminology, the "ear", where it connects back (or flows into) to the main part of the knuckle, is where the breakage/shearing has occurred.

Any more ideas on what would cause this?

 

I would venture to guess that a very, very bad front end alignment could cause it but the most likely reason would be somone abused the equipment to and extreme and rather that replace the knuckle they jury rigged it. Not only very dangerous, but stupid as well as it seems to not work as a fix.
