  1. Check companion flange or yoke nut for looseness and torque to proper specification if necessary.

  2. Driveline slip joints that do not have the arrows or other markings pointing to each other will result in the driveline universal joints being out of phase. In altre parolle, the transmission universal joint may be turned one spline or more to the right or left of being aligned with the universal joint at the opposite end of the driveline.
    • Some computer designed drivelines are purposely built with U-joints out of phase. Check manufacturer’s specifications for proper setting. Also, check closely to make certain no twist has occurred to the tubing, causing these two joints to be out of phase Make sure the slip joint works freely and is not bound or seized. Slip joints must absorb axle housing movements.
  3. Unbalanced drivelines can cause vibration that occurs throughout the speed range of vehicle and varies in intensity with a change of speed. The driveline may be at fault in respect to balance and concentricity. A quick field check to determine driveline balance can be made by securing a small piece of metal or similar weight with a hose clamp to the front of the tube where the splined shaft is welded. Road test the vehicle and continue to move the weight around the tube until the balance point is found and vibration disappears or is minimized.

On articulazzioni tipu piaghja, it may be necessary to remove the bearing cap. Quandu ripiglià simana, make sure the universal joint is in a vertical plane. At the rear axle, take readings from a machined surface differential carrier that is in the same plane as the axle pinion shaft, o da a superficia machined chì hè parpindiculari à bearing crimagghiera, whichever hè piuttostu.

Se mangianu polzu, mentri iavanu viotu, take readings in empty condition. Sè si faci quandu carricu, take readings when loaded. When it is necessary to measure driveline lengths, measure from joint center to joint center

If vibration persists after adhering to manufacturer’s specifications, contact the manufacturer’s representative.

    • angle, XL. Take reading either from machined surface of axle housing or pinion bearing retainer. This angle must be within one degree of the transmission angle.
      • esempiu: If transmission angle reading is 3 degrees down to the rear, the rear axle angle should be 3 parallel of su.
  2. Tandem nc o veìculi cù Mancusso Ausiliari

    • Take reading from joint of front tandem axle or auxiliary joint. This reading should be within one degree of transmission angle.

    • Pagliacci,, lettura di angle, giuntu a Tandem XL arrière, or axle to rear of auxiliary. This angle must be within one degree of transmission angle.

Limiti Joint Angle Rossi (pattu)

articulazzioni Universal hannu un angolo massima travagghiatura, secondu u tippu è cunfizzioni. Hè cunsigliatu chi l 'àngulu di travagghiatura signu di assemblea giuntu tempu ùn trapassa 8 livelli di drivelines principali più di 40″ longu. Per drivelines principali sottu à 40″ l 'angle, massimu ùn trapassa Length (L) divisu da 5. (Stu limitu ùn dumandà à interaxle drivelines.)

esempiu: Per un 35″ driveline, the maximum joint working angle would be 35 pluma 5 o 7degrees. This working angle must not be exceeded.

Place protractor on driveline to obtain angle of driveline from transmission to axle. The difference between the driveline angle and the joint angle is the joint working angle. For instance, siddu la trasmissioni hè 3 parallel of falà, and the driveline angle is down 7 scaleddi, the transmission joint working angle is 7 Minus 3 o 4 scaleddi.
U fundale Tandem, o strutture ausiliari, take readings in the same manner, comparing the universal joint angles to the driveline angle to which it is attached.

Take readings between transmission and front tandem axle, or auxiliary. Take readings between axles or between auxiliary and axle.
