I own a 2012 jk, 2 door, 12 000km on it, 6 speed manual tranny.
since a couple of month, maybe 2, when I give a load to the driveline I hear a cracking sound coming from the driveline, i guess.
It happened first on 2wd, during fast stop/reverse manoeuver on pavement, and for sure it's not a bad engagement from the tranny.
And then, it happened on 4low, still while giving a load on the clutch to get out of a rut. It seems to come either from the rear driveshaft joint or from the rear differential.
I've experienced something very similar the other day. A costumer came at the shop for a similar sound on a 2012 F150. At first it seemed to come from the rear joint at the rear diff, so we changed the joint and the trouble was still there. It's the model that have 3 joints with a center bearing, so to save time, we took a driveshaft on a new truck and tried again, and still craking under load. We were able to make it happen when doing stall test (giving gas while holding strong the brakes). Finally, we opened the rear diff to inspect, still nothing unusual, no weird vibration from the cage, gears or bearings.. BUT, the cracking sound was very strong. At this point, the only option left was the pinion and/or its bearing.
Anyone experienced similar problem?
