i think im running into axle issues. when i shake my tire i can hear fluid swishin and swashin around. my back end is also pretty loose on bumps, especially at highway speed.

any ideas?

 

Fluid swishin and swashin=gas in tank.

Loose rear.

 

First thing that I would think of would be the gas tank, I know there have been times when I've heard it much louder the normal for whatever reason and made me pause and think wtf for a second.

As for the loose end, try checking the torque on the rear track bar. I know mine wasn't as tight as it should of been after my lift and it felt pretty loose, turns out it was just the lower track bar bolt that felt tight but wasn't tight enough.

 

yeah, found out the issue today. that was the gas tank and like you said, just seemed much much louder than usual. wobble came from wheel weights falling off and rattling the track bar just a smidgen loose. felt kinda sketchy on the highway but now that its all buttoned up, its good to go
