30-40mph vibration issue!!!!!

so i raised my billies to .85'' and there were no vibes and it road great. i decided to make the truck level so i put the billies to 1.75'' and immidiately go vibes. i read that its the front differential bearing. and at that height it shows itself.
my question is... should i pay to get it replaced event hough its very expensive? or is this an issue that i can just deal with? meaning continue driving the truck and i have no problems with it. or will something eventually break and be 10 times worse if i dont fix it now?

 

Does the vibration go away if you put it into 4WD !!!!!!!!???!!!!

 

it is not a hard fix, but 120$ for the tool and bushing can suck.

over time, it will destroy your bearing, and your inner axle stub. I don't know how long it takes. if you were closer to me I would fix it for a couple beers. . . . its that easy

 

Yes it goes away in 4wd.

I heard it was like a $1500 job?? Anyways it's probably in my best interest to get it fixed

 

Anyone else?

 

So I brought my truck in to toyota and of course they don't feel a vibration. I'm at a loss on what do do. I think I'll just drive it till it breaks? Any suggestions?
