vibrations in front axle and 4wd light stays on
about a week ago, i was driving along a bayou on grass(i was in 2WD at the time) when a large mound covered with grass came out of no where and i flew about 4 feet in the air. i initially was afraid that i mightve broken something but all that i noticed were my wheel fenders popping off so i thought nothing of it. earlier today, i went into 4WD to get better traction in the rain and then once it stopped i took it out, but the light stayed on. i jacked it up and checked the tires and the vacuum lines and even though the lights on, only two tires are moving. i took the vacuum lines off and only one is getting suction and thats the one that is NOT attached to the transfer case. i also noticed that around the time of the light staying on, there was a fierce vibrating in the front axle when going around 55mph which couldnt be from the jump because i could easily drive fast after it and this only started today. are these problems related? and does anyone know how to fix them?
