Depends on the condition of the driveshaft. In some instances, you can just get it rebalanced.
Well you can't actually accellerate with a broken drive but however if the drive shaft breaks while you are driving your vehicle will keep moving providing you don't press the brakes
Chock the wheels to be sure vehicle will not roll. Mark the differential and drive shaft before removing drive shaft. Remove 4 bolts from differential-end of drive shaft. Place a pan under the transmission-end of drive shaft and have clean rags handy. Push the drive shaft slightly toward the front of the vehicle while pulling downward on the drive shaft and lower it to the ground. Pull the drive shaft toward the rear of the vehicle until the front of the drive shaft pulls out of the transmission. Place the drive shaft on the ground and put rags in the transmission to prevent oil leakage and keep dust/dirt out. Assemply is reverse of removal with special attention to aligning marks on the drive shaft to the mark on the differential.
If you are changing the height of the vehicle and not the length you may be able to keep the same drive shaft. However if you change the height by too much, you may have to get a longer drive shaft. Try it with the shaft you have after the kit is installed and then you will know if you need to change your shaft.
A drive shaft is generally a hollow metal tube. The tube has a plate welded onto each end with the proper coupling for the cars transmission and rear ends to mate to. The entire assembly is balanced to keep vibration to an absolute minimum.
The best way would be to remove the drive shaft from the vehicle before towing. Many transmissions do not circulate the transmission oil or fluid unless the engine is running. Removing the drive shaft will keep the rear output on the transmission from turning while towing it.
put the transfer case in 4x4 and put it in gear
A worn pinion flange or the drive shaft where the u-joint goes in these holes may be wallered out some
First block the wheels to keep the truck from rolling. It does not matter if it is in park It will still roll when the drive shaft is out. GOT IT. SAFTY FIRST. Now craw under the truck and you will see where the drive shaft hooks to the rear end. There is 4 bolts, 2 on each side, remove them and take big screew driver and pry the drive shaft out of the yoke. Then pull it out of the transmission. You will loose some trans fluid.
Concentrate on a steady base and drive through the ball after contact instead of falling back.
Your angle is too steep and your drive shaft maybe too short!
it is at the back of the motor, near the center (if you go under the car follow the down pipe past the sump, when you can see the drive shaft it should be visible, just to the side of the down pipe, above the drive shaft). when you change it, they always spill oil onto the driveshaft, it will miss the exhaust but keep a rag handy when you do this.
The shaft should last forever, but u joints could go on a high mileage vehicle. Keep them greased and they last longer. Excessive play in shaft when moving back and forth by hand, a vibration not attributed to wheels or wheel bearings or only at a certain speed or a clank when putting in gear are other signs. see article
