Thanks! Should I upgrade the mounts? To OEM or is another recommended?
Well, that makes sense. I was heavy on the throttle to keep it going up the hill without stalling and was moving faster than was comfortable. Going slower would have been much less scary and increased my control while improving my reaction time. Preventing the hop is a big bonus.Another reason for the dual cases... Now I am really getting excited about getting this done! Sounds like this will solve many of my trail challenges.
Since installing my Old Man Emu lift I have had a vibration in the back end, particularly at high RPMs - could that be due to a steep rear pinion angle?
How do you control the driveline angle - lowering the Tcases, change the Tcase mounts, modify the axel/diff? How do you measure/set the angle to get it right?
I purchased some new leaf spring perches. Also purchased a magnetic angle finder. Took a few measurement where old perches where located. Cut off old. Cleaned up. Tacked new perches. Installed ubolts, just enough to snug it all up. At this point. With vehicle on all four tires. I loaded roughly half my stuff that I take wheeling. Then used my floor jack and a piece of wood, placed on pinion housing. Make sure your on the housing. Using jack. I broke tack welds. This allowed me to adjust my pinion angle. Afterwords I tacked again. Then removed axle so that I could finish welding. Regarding getting the angles dialed in... I positioned my pinion exact with driveline angle. After triple measuring, and writing a few notes I then positioned rear pinion 2 degrees down.
Dual OEM (so really one new) is what most would recommend I think.
Could be, could also simply be your u-joints are due to be replaced, 2" or less of lift usually doesn't cause issues with u-joints. U-joints wear in their normally operating angle, when worn, vibrations are normally felt under acceleration/deceleration through the seat due to the change in the angle of the u-joints, and normally felt before you hear the "ping" when backing up or moving forward from a stop. The small lift from the OME springs, put the u-joints in new angle, likely the same as under deceleration, or a little steeper, and is likely why you feel the vibrations.
You'll likely be doing drivelines if you make the switch to dual t-cases so keep that in mind.
What you were experiencing often ends with broken drivetrain components as well, another benefit of being able to move slower over the same terrain.If you haven't seen the speed at which dual cases can go, the store has a video herhttps://www.marlincrawler.com/gallery/videos/transfer-caseand others like this one can be found on youtubehttps://www.youtube.com/watch?v=uMvCChImPPQ
