Drone after lift

Hi all! A couple of weeks ago I had the Superlift installed on my XK. I have the AEV XK Pintlers with 285/70R17 Wrangler Silent Armors installed.



So now at highway speeds (> 50mph) I have a drone of sorts that's rather annoying. I have had these tires in the past in stock size and know they can be nice and quiet. So I'm wondering if the drone has to do with the balancing method used. Anyone have any knowledge/experience with this? Could the drone be due to something else?

Yes, the drone continues.

I would doubt it would be the bearings since just before the lift all was well.

There was a moment I thought of the exhaust droning, but that would be a bit too coincidental, too. But when I rev the engine there is no strange exhaust noises.

I had a problem with a ford sport track, guy insisted it was the exhaust. Front pass bearing. The fact that the lift was just installed could have been the stresser... FWIW

Just a thought, is there any chance you popped a small hole in the downpipe when you dimpled the exhaust, and its expanding when you get that monster moving 50mph? Possibly have some rubbing on the driveshaft?

Also, in regards to your tire balancing: What method exactly? I use the auto-balancing beads in my Duratrac's and don't have too much nub rumble.

I suppose it's possible the exhaust has a small leak now. I had a professional install the lift, so I didn't personally modify the exhaust pipe. Since I'm recovering from surgery now, it'll be a couple of weeks before I can slide myself under to check myself.

Concerning balancing, I think he said there is static and dynamic balancing. With one method he was able to use less weights to obtain balance. The other method needed like 14 oz. on a wheel for balance! I don't recall which was which.

Sounds like bearings even though you said you just changed them. The drone from them is so annoying. I'm currently saving up to fix mine.

Well, I thought I'd report back in with some answers.

The drone was caused by a bad pinion angle in the back caused by the longer SL lower control arms. I got a set of adjustable uppers from Rusty's to compensate, and all is well. There are pictures up on TUJ.com.
