OK Guys this is my last resort. I can't seem to figure this one out. Please Help.
Here are the stats on my rig:
- 5.3 V8 Swap with 4L60E
- AEV Pintler 35" wheels with Spidertrax adapters / Falken AT tires
- Stock Dana 30 up front
- Ford 8.8 in Rear
- Upgraded JE Reel Driveshafts front and rear
- Super Short SYE
There are a bunch more mods but that the basics...
I'm getting a moderate vibration at about 65MPH to 70 MPH on the highway. one large enough to be concerned with. From the frequency of the vibration I thought it was rotational it seems to come from either the center or the front of the rig but I can't really isolate the location. It doesn't escalate when you hit a bump and you can slow down to 50 MPH and it goes away.
What I've done:
I thought it was either a driveshaft or tires. I replaced both of my driveshafts and put brand new AT tires on with brand new wheels but no luck. I then went to steering did the whole move the wheel at 10 and 2 while someone checks the linkages... I replaced some of my stock steering components and nada. I checked for trackbar movement and it looked fine to me. I also checked Ball joints, unit bearings, all my control arm bushings.
I haven't been wheeling lately in the rig. It was perfectly fine and then all of a sudden out of the blue, the vibration appeared. So, I don't think it could be an axle.
I'm am at my end with this issue! Where do I go from here???
I know there are tons of threads and I have done everything I can think of....
Thanks for your advice!
