Probelma de vibracion en Grand cherokee HEMI
 

Amigos.

Mi tio tiene uno de estos bichos y tiene una vibracion que te la encargo
tirita completo desde los 60 hacia arriba,
en el taller lo han revisado y no le encuentran nada

Se les ocurrio que podia ser la traccion inteligente (le pusieron un computador de uno nuevo y nada)
le han hecho de todo,

Yo estuve leyendo en foros gringos donde les cambiaban el rear drive-shaft y el front drive-shaft y los CV u-joint

drive shaft que es lo que es??? CV u-joint(son las uniones del cardan)

Ayuda porfa

Que lata, gastar tantas lucas en algo que da problemas, se repite mucho en vehiculos de origen USA, cada dia mas me convenzo quelos japoneses son lo mejor que hay.

Saludos...

Rear y front drive-shafts son los cardanes trasero y delantero.

Salu2.

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. Over the years I have heard much discussion about the causes of DW and have come to a conclusion - DW isn't caused by any one factor, but may happen if any of the following are present (not necessarily in this order, either):
Poor alignment. The first question I ask these days when someone has handling problems after a lift is whether they had the vehicle aligned. More than half the time, it wasn't. Don't proceed until that's taken care of.

The front tires will be toed-in following most lifts, especially on the LJ, MJ, TJ, XJ, and ZJ because of the steering arrangement. 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. Sometimes this can be caused by excessive toe-in of the front wheels-think of it as the tires being cross-eyed and not knowing which tire is dominant

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 is worn or the trackbar mount is loose, it can allow lateral wobble as described above
Trackbar, Pt II. The trackbar mount at the axle end can loosen up or 'egg' the hole and cause a lateral wobble or wiggle.
Poor Alignment (Part II). Lifting the Jeep involves changing the caster of the axle. If the stock control arms are used, the pinion will start pointing down, away from the t-case output shaft. As it points down, it changes the caster of the axle and therefore throws off the self-centering engineered into the axle. Remedy this by using adjustable control arms.
These figures are according to '94 factory manual except where noted. (may vary for 2000+ low-pinion axles and pre-91 disconnect axles).
Camber (not adjustable) = 0 degrees (+1/2 to -3/4 acceptable)
Caster = Manual tranny +6.5 degrees, auto tranny +8 degrees (5 to 9 acceptable)
Toe-in. Depending on the year of your Cherokee, toe settings will vary.
87-94 you want 0" inches, + or - 1/16
on 95-96 you want 0" +1/8 or - 3/32
on 97-98 it's 0" +1/4 or -3/32
on 99-2001 its 1/8" +3/32 or - 1/8
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.
