I get a shake when i engage my 4x4 ? its good at slow speeds but if i go faster than around 40-50kph she starts to shake the front end only in 4x4 would that be a u joint?


Thanks

Are you running on dry pavement?

 

Check trans mount.

 

dry pavement, gravel but only at higher speeds, and only in 4x4

 

why are you driving on dry pavement in 4x4? THAT could be your problem

 

icy/very snowy sections

 

tires balanced? and possibly a ujoint, for the front driveshaft

 

Thats not dry pavement!

If its only happens in 4WD, it really doesnt sound like a problem. A U-joint or driveshaft problem would show up all the time. If you think it is a U-joint, freaking check them!

Also, you never posted your name, what kind of truck you have, or any welcoming.

Welcome to dodge forum, its normal for 4x4's get use to it

 

well when he is in 2wd the front driveshaft is unlocked/free, then when he puts it in 4x4 it puts the strain on it to make the u-joint wobble/make vibration yes?
