Hey, noobie here. Just recently noticed that what when I shift my 4wd lever from H to N its has this vibrating rattle, it also happens when i move it from N to L4. I tried it with engine off and nothing. Tried again with it running and still making like a stuck noise. please help. i really love my truck want to fix :/

 

Start with the easy first check the transmission mount

Have the bushings in the shifter ever been replaced ?
