There's so many threads with scattered info it's impossible to tabulate anything, so I'm asking directly for answers to the following questions - please respond EVEN IF YOU DON'T have the oscillating vibration issue. The more data the better, and I can put this in Excel and pivot table the $#!+ out of this.
1. Do you have the oscillating vibration issue and at what speed does it start?
2. does it persist even with the front driveshaft removed?
3. Model year and TJ or LJ
4. Axles and Gear ratio (and if you have a Rubicon, did you keep thick cut gears or did you get a 3.92+ carrier and go to standard gears?)
5. Tire size
6. transmission
7. transfer case, and if 231, is it SYE'd
8. stock or aftermarket transfer case skid, and if aftermarket, which skid (please include brand, tuck height, and material)
9. stock or aftermarket gas tank skid, and if aftermarket, which skid?
10. suspension lift height, if any
11. any other mods that might change the way the frame is constrained, such as a stretch, midarm, rear frame raise, crossmember deletions, spring perch relocations, shock outboard, etc.
