I'm getting a silly driveline vibe at 85+, which totally sucks because 85 is how fast everybody goes on the 15 fwy by my house. I was totally expecting it when I put the 3.73's in, now it drives me crazy and I want it to go away. I just replaced the trans mount/engine mounts while the engine was out, and I replaced the bushings in that dampner thing that hangs off the bottom of the diff housing because it was looking kind of droopy. My control arm bushings are no doubt stock, and they look pretty sad, and I was planning to buy some kickass control arms to replace those all together, but dont want to do so if that isnt my vibration, or if replacing them is going to make it worse if its something else. So do I spend some cash getting the shaft balanced or man up and get some arms, or is there something else I should do? Thanks!!!

Remove the dog bone weight (the thing you changed the bushings in) and see if the vib goes away. Even if it does or does not fix it you can leave the weight off, it does nothing for gear ratio's above 3:55. An aluminum drive shaft is also a common fix for high speed vibs after gear installs.
Yeah I ruled tires out, It had the stockers on it when I did the gears, no change when I put the KMC's on. I balanced em at work and we just cal'd the machine in feb. so they should be good. I'm gonna try pulling the dog bone thingy and see what its like, then I'm gonna go buy a shaft. woohoo!
