    15 Lml vibration not factory issue

    So I randomly fixed the vibration I drained the fluid which btw I changed it and tranny when I did my gears bought oil from Gm for this transfercase well I drained it to see if there was metal shaving or not and I didn’t have any of that oil so I put in 5-30 motor oil and vibration is gone *♂️

    15 Lml vibration not factory issue

    I’m down to either transfercase or rear yoke or converter it’s a go rend converter so I don’t think it is it plus it doesn’t do it in any other gear at that rpm. But I’m not sure how that works

    15 Lml vibration not factory issue

    Truck is 4 linked in rear and old driveline was 1.5 inches to short so I figured gearing lower caused driveline to vibrate so built new one longer and used spicer joints. I’ve never seen gears cause a vibration also backloads is 5 thou where I set it wear pattern looks great
