Hey everyone. I'm seeing different numbers through the threads on engine and frame torque specs for the motor mounts. I'm replacing mine this weekend and wanted to ask if someone had the true numbers for them. 2017 Trailhawk 2.4L. Many thanks.

I've only replaced the passenger side motor mount on my 2015 2.4 and I called the dealership service dept. They told me the spec was 83 ft/lbs for this mount. Might not help you much but you could make a phone call and see how helpful they'll be.

Thanks for the input. Based on the chart one of the stock Class 10.9, 18.4 mm bolts would be 240 ft/lbs? Wow, I had no idea. Yeah, I'm waiting for the dealer to call back and see what they have to say. Wanted to chime in with you guys about it too. Thanks again all.
