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!!!
