tarkoita DEATH WOBBLEa?
tälläistä löysin:
If you're asking what "Death Wobble" or DW is all about, it is a situation where the front axle begins oscillating with such violence that control of the Jeep is difficult until slowed down, and the entire vehicle shakes to the point you feel it will come apart. Although I have heard much discussion, DW apparently isn't caused by any one factor, but may happen if any of the following are present:
Poor alignment. The front tires will be toed-in following the lift; when you hit a bump on only one side of the axle the tire will begin to bob up and down. Since the Control Arms are no longer horizontal, they will pull that side of the axle farther back as it goes down - this will turn the wheels slightly to that side. Once the tires pull to that side, the 'scuff' of the vehicle traveling straight ahead will slow the tire and begin the same process once again. Drop Brackets can also help reduce this, since they bring the control arms back to a more horizontal position.
Poor Alignment (Part II). Lifting the Jeep involves changing the caster of the axle. Since this impacts the self-centering of the front wheels it can throw the wheels back and forth again.
Loose or worn Trackbar mount. The trackbar prevents (or reduces) side-to-side motion from the four-link front suspension on the XJ, MJ, TJ and ZJ Jeeps. If the ball joint os worn or the trackbar mount is loose, it can allow lateral wobble as described above
Unbalanced tires. Once again, as they start throwing the axle around, the only way to stop it is going to be by slowing down.
Steering Stabilizer. A tight steering stabilizer can mask problems with the steering, but if it's loose it may allow DW to occur in cases where it normally wouldn't have.
Ball joints. Worn ball joints are a danger anyway as they may fail and cause uncontrollable steering loss, but by allowing the wheel to move laterally and independently of the opposite wheel they can also contribute to DW.
