2nd Gen Non-Engine/Transmission Front end shake

[JKaiser]

I have a 2001 dodge truck. When I try to run in 4WD I get a shake in the front end. Take it out of 4WD and the shake stops. Any ideas?

Check Front Drive Shaft "u-joints"

Remove front shat, run in 4wd H if still there it's not the shaft, look to axel joints. If with the shaft out no shake then the shaft may need the double joint or new universals. Have fun!
