Title: Transfer Case Shakes
Post by: krafty33 on February 06, 2010, 08:31:32 pm
I am noticing a some shaking in my transfer case at low speed (10-20 MPH). Would bad front ujoints cause this. The only reason I am asking is because I think the joints are going bad.

well if you read one of my last post in "more snow" i also have the 203 with the kit tho but i was in 2hi if my hubs are locked it will make clucks and stuff and vibrate and in 4 lock it will do the same thing well today it broke up by the t case and the second joint not sure what failed but i see one joint just sitting in the shaft. i guess its just due to age but idk but like you said the u joint could and would cause that problem. and about your spline problem if you don't drive it that hard i don't see why 2" would hurt it but if you mud and drive it hard yeah i would like to see more

U-joints can cause a vibration in the transfercase but when do you feel the vibration?

Low speeds mainly...I was doing it in 4HI but I also noticed it in 2HI. It seems to do it when the hubs are locked which is makin me think joints. I also just put a 4 inch lift in and there was a spot where it said to grind the stops on the CV joint. I didnt do it cuz it looked ok....maybe its hitting a bit. I am gonna start with the joints

well if it does it in 2hi it ain't the front joints since nothing spins with the kit. make sure it ain't the wheels, busted beads can do it too
