I know there a crack in this but don't know the name of the part to replace it seems easy to do. I have a 2001 jeep Cherokee sport 4x4

 

That is not a crack. That part is called tie rod adjusting sleeve. It's pretty much a piece of metal rolled up. When you tighten down the nuts, it clamps down on the tie rods.

 

Ok I'm trying to figure out why when I give it has it make a funny noise I don't know if it's the hub or the tie rod going bad. It's raised 3 inches

 

Best way to find the noise is have a friend help you. That particular part has nothing to do with when you give it gas. If you have something loose in your suspension, have a buddy jump up and down on your bumper while you lay under it and locate the sound. Welcome to Cherokee Forum!

 

If I had a part "crack" and it was as straight as that, I'd be extremely impressed lol.

But yeah, that's normal. I'd be looking elsewhere for the source of your noise. Maybe source some help from someone a bit more knowledgeable if that's possible.

 

FWIW a raised Jeep makes funny noises- suspension loves to squeak n moan

 

It's when it stops making noise I begin to worry

 

Did you ever figure out where the noise is coming from?

How about Ralph? Ralph is a good name.
