Ok Jeepers. I need some help. I have a 2016 Jeep Wrangler Unlimited Sahara. Wheel hubs are new, new drag link, new tie rod. I have an AEV 2.5" lift and a JKS adjustable track bar. I keep up on maintenance, but I am at a complete loss trying to figure this out. I noticed when I am braking at low speeds, and when hitting the gas from a stop, I get a "rumble strip" feeling/vibration in the front end. I thought it might be my 1310 double cardan driveshaft, so I pulled it and drove without it. The vibration/rumble when braking is still there. Any ideas?

 

What kind of tires are you running? My old Bighorn Maxxis started that same thing as they aged. No more MTs for me with the big lugs causing that. Apparently our friend who manages a tire shop says they do harden after a while and mine is garage kept. Mine weren't rumble strip loud but one could hear and feel them vibrating at low speed. You sure it's the front?

 

I am running Goodyear Wrangler Duratracs.

 

Ok! Problem solved. It wasn't the driveshaft, wasn't the hubs, the braking system, transfer case, trans or diffs. Bad left front tire (possible factory defect). All other 3 tires were perfect. Left front was wonky. Put the spare on the left front.....vibration GONE!!

 

Thanks for this update and good you found the culprit.
