What should front pinion angle?
5 to 5.5 degrees or higher is normally enough, with larger tires not needing as much caster angle for good return-to-center as smaller tires do.
What is an advantage of a double cardan joint?
The real benefit to a C. V. (double cardan) drive shaft is smoother operation at higher operating angles and longer life. The C.V. assembly works by intersecting the joint angles at the center pivot point and delivering a smooth rotational power flow or surface velocity through the drive line.
What is pinion angle Jeep?
Pinion angle simply refers to the angle of the differentials pinion in relation to the driveshaft. To get a range of opinions, we spoke to several well-known and respected chassis builders about pinion angles.
What should my driveshaft angle be?
1 to 3 degrees
Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration. If your angle is larger than 3 degrees, you must make sure not to exceed max driveshaft RPM as shown on this Spicer table.
How much pinion angle is too much?
typically over 1 degree. More than 4 & you have the opposite effect of too much wear due to excessive movement & the potential for increased vibration. 1-2 is probably an ideal range. Keep in mind performance applications tend to run more angle due to the suspension flex under hard acceleration.
How do you know if pinion angle is off?
So what symptoms would lead you to identifying bad pinion angle? Drive train vibration at speed, wheel hop and universal joint fatigue/failure are all good indicators. These things can come out of no where with suspension bushing failures, engine and transmission mount failures or even leaf spring fatigue and wrap.
How much drive shaft angle is too much?
Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration. If your angle is larger than 3 degrees, you must make sure not to exceed max driveshaft RPM as shown on this Spicer table.
Is 5 degrees of pinion angle too much?
Here’s an illustration of what things might look like with too much angle, it’s exaggerated for effect, but imagine that’s 5 degrees on each end. So, with too little of an angle you’ll wear out your u-joints, but too much of an angle you’ll wear out your u-joints and end up with some nasty vibrations.
How does a double Cardan drive shaft work?
The double cardan assembley has a centering mechanism that keeps the angle between the U-joints correct, allowing them to completely cancel out the speeding up and slowing down and spin the drive shaft at a constant speed.
What should the pinion angle be on a jeep?
Unfortunatley, our world isn’t perfect and the needle bearings inside a U-joint need to move to stay lubricated. The pinion angle must be 2 degrees below the drive shaft in to cause the needles to move and be lubricated.
What kind of CV joint does a 4 wheeler have?
The double cardan type is the CV joint with the two U-joints at one end that is so popular with 4 wheelers. The caged ball type is similar to a CV joint in a front wheel drive car or a birfield from a Samuri or Toyota front axle.
Why is the pinion pointed paralell on a CV joint?
In a perfect world the pinion could be pointed paralell with the drive shaft when using a CV joint so that all four caps on the lower U-joint will spin in the same circle to prevent the single lower U-joint from speeding up and slowing down as it rotates, which would cause a vibration.
