Figure this one out! HELP!!!
2011 JKU
2.5" inch RK Max Travel
1" TF coil spacers in rear (heavy rear bumper)
4.88 gears
Problem: Driveline vibration and slight hum coming from somewhere around t-case
Diagnostics: Front driveshaft removal, vibes still present. Rear removal, still present. Tires balanced and rotated, still present. Stock tires put on, still present. No tires, placed on rack with front shaft only connected...you guessed it...still present.
Hum and vibes HAVE TO BE t-case. Local shop belonging to a friend did all diagnostics.
What could be making the t-case act like this? Fluid has been replaced. No shavings or anything. Shifts fine.
