DW caused by driveshaft?
The back story is I have a 2004 Grand cherokee with a 4" IRO front long arm lift kit. I'm running 32s on the stock rims. I have had the kit for roughly 2 years and have been fight DW since about 2 or 3 months after the kit was installed. The jeep has had 15 alignments, 30 wheel balances and rotations, the IRO track bar that failed was replaced with a JKS, Dual stabilizers and have even gone as far as adding an upper control arm to the passenger side. It has been to 2 mechanics, 2 4x4 shops, 2 different tire shops and i'm currently sitting at roughly $5000 after the lift kit. If there is a DW list out there I have run through it.
At 45+ mph and you hit certain bumps the entire vehicle trys to shake it self apart (DW). Everything that has been done to it seems to fix it for a week or so then it returns. The newest theory is this, when it's a bump that drops the front axle and extends the front drive shaft it causes the drive shaft to get outta balance or gives it an extreme angle and that is what is currently causing something extremely like DW. Until you slow down and almost stop or stop, which slow down the shaft, it vibrates so hard that it is transfering this out to the wheels into the steering wheel. I do have the IRO transfer drop installed. There is also a vibration that occurs at around 60 or 70 mph just running down the road that occurs around the transfer case.
Has anyone had an issue similar to this or this exact issue. Or does this seem to sound like a reasonable idea. I'm really looking for a 3rd opinion here because like I said I currently have proabably one of the most expensive 4" lifts on the road. Any help is appreciated even if you tell me that me and the 4x4 shops are going crazy. Thanks for the help
