I would try to match it up with another store like Napa first,
see if it's the same as the one you have, or if AutoZone has
a bad/wrong part

ok thank you for your advice i see you all over this place giving awesome advice keep up the good work!!

well i went to autozone oriellys and napa spent 4hrs comparing parts lol and they are all the same so i changed the bushings in the back and it is tighter but i'm afraid it won't last long what greese should i use???

It sounds like the bushing seat may be hogged out from wollowing around in the spindle. How easy was it to press in the new bushing?  If that's the case, all the new bushings in the world won't make it tight again. You'll have to look for a replacement spindle that hasn't been worn out. You can probably pick up a decent set at the u pull it or even here if you post up "wanted" in the classifieds. Or you can machine out the hole to accept a custom bronze bushing, and cut one or two oversize ones out on the lathe.

I wouldn't think a bronze bushing would hog out a steel spindle, but with enough
heat from friction I guess anything is possible

Bronze wearing out steel?  I don't think so.  The only thing that remotely makes me think that would be possible is Bent said it.

If the bushing got loose in the seat, I could spin, or wobble. I know it's a long shot, but something to check. Yeah It doesn't sound likely, but I have seen cast iron bushing seats enlarged by wallowing bronze bushings. Just on a lawn tractor though

I know it's an older post but I believe my tracker is making the same noise.  it howls when I have the hubs locked in but as long as it's under load in 4wd it doesn't make noise.  where did you find the brass bushing that you replaced and how hard was it to press out?  Part number would be great, I can't find it online at autozone or napa.  any help is greatly appreciated.

Thanks guys

It's a split bushing pressed lightly into the knuckle, I would go rob them
from a wrecking yard track/kick, I have no idea if you can order them.

I know this may sound crazy but you can sometimes find bushings by size ibetterhardware stores, occasionally a Lowes or HD in the hardware isle in those grey bins. Tractor Supply is another place to look. Or Fazzzio's here in Jersey. Probably wouldn't bother to tell anyone ther it for a "Suzuki." They'll just look at you funny and say " we don't got them." If you can find the correct ID even if the OD is larger you'll  need to oversize the knuckle to get it round again anyway. any machine can make you one too but a salvage knuckle with good parts will probably be cheaper. Got a lathe?

The factory bushings have little dimples on them, I assume to
hold a little grease in them to aid in lubrication
