Apparently it's a design flaw some have seen with the motor mounts. The drivers side is the weakest due to engine torque.
You need these:
S2883-PHW, Pair 4.0L Header Super Engine Bracket for TJ and LJ
and replace the OEM motor mounts with Brown Dog rubber mounts. Good time to do a BL/MML if you were planning on that at some point.
Around here, you find ripped OEM motor mounts on the trail sides quite a bit. Mostly ripped rubber, not so much shearing off the block tho. People end up having to leave the vehicle and do a trail repair later.

Engine bracket bolts broke (again)
I'm wondering if anyone can help to shed some light on what is now a reoccuring issue I'm having.
06 X with the 4.0, no lift. About 5 weeks ago the kids and I were running through our woods and hit a pretty serious bump. The shifter kicked way over to the left. Came to find out that the driver side engine bracket bolts had sheared.
Replaced the bolts with OEM ones I got from the local Dodge / Jeep dealership. I also went ahead and put in another driver side rubber motor mount.
Last night, we were heading up a muddy road that was a bit washboarded. Never got above 15mph and road in 4WH due to it being a pretty steep and slick grade in spots. Shifter kicked way over to the left again and the bolts had sheared off at the block. Driver side again.
Limped it home 22 miles at 30 mph and parked it. As a short term fix, I'm going to replace the bolts again on the driver side but also gonna replace them on the right side for fear they got stressed after the long canted over ride to the house. As a long term fix, I'm gonna put Brown Dog's on the Jeep and be done with it.
Anyone know what causes this?
