Just got back from my first pull
I drove 13 hrs. in 1 day from Fort Collins CO. to Durango CO. than to Moab Ut. I pulled my crawler on my 20' gooseneck and was pleased. this drive consisted of hills upon hills and mountain passes so I averaged 10-12 MPG's. Does that sound correct? the trailer is about 4000 lbs. so I assume that's about right considering the passes. On the same drive back, I didn't have the trailer but had the bed loaded and averaged about 18.5 MPG's. I than got nasty vibrations in higher RPM's. I don't think it's a drive line because I'll shift and vibrations go away till I reach higher RPM's again. This trip ended yesterday so today I will chek motot and tranny mounts along with the driveline. Any other suggestions?

Maybe check clearance of the Downpipe to the Firewall seam? Just a suggestion.

Just looked at everything and it looks like the vibration is from the motor. All the mounts look good and the idle sounds normal but the motor is moving a bunch causing the vibration. It shakes the whole truck at idle. any thoughts

There is no way he's running a DMF with stage 2's. If he is, whoa.

Is the DMF the first thing we're supposed to change?

My DMF wouldn't even hold up with stage 1's. For yours to hold up with stage 2's is pretty amazing.

I know that it's 2 flywheels seperated by a bearing and I'm told that the baring is what fails.


After Easter Jeep Sefari I'll get pics of the four links. I left the crawler near Moab where I can't get to it.
