WHY!? Weird Noise - Rubbing/Vibrating
OK so i got the first round of upgrades on my 2012 JKUR. (6speed)

- 3.5" AEV lift
- AEV Pintler
- 315 Duratrac tires

90% of the time when i start to accelerate I hear a weird rubbing noise coming from under the car. Initially i was told that it was wheel rub because I had stock wheel/tire on a lift. Since then, I've upgraded to the Pintlers and I still hear the noise.

It's starting to drive me crazy! what can it be?

I eventually want to upgrade Driveshaft and Exhaust, but I don't think thats the case at this point in time.

Any thoughts??

Edited because the next two post make much more sense.

Sounds like driveshaft, especially since you mentioned accelerating. I know my 3.5 aev coils provided quite a bit of lift and you'd need a driveshaft sooner than later. You should be able to tell the difference in sound relative to speed. Tire rub would be much slower then a driveshaft at speed. Have you crawled under to check on marks to driveshaft, tires, etc? I wouldn't think wheel weights as there's plenty of clearance with stock 17s from calipers. Unbolting a driveshaft and going for a drive may help with figuring it out.

I agree with drive shaft especially since it did it with the stock wheels and tires. Was the pinion angle checked and corrected after the lift was done?

Not trying to bring up the past but this is also my story to the day! OP what did you end up doing...?

That's ok with me. So many posts with no follow up is a bit annoying.
