What degree do you set pinion angle at?
According to Currie, the average car crafter should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram).
What should my front pinion angle be?
The two round circular flats on either side of the differential cover are perpendicular to the pinion angle. You can rotate most angle finders 90 degrees until the angle it indicates is the pinion angle. The front pinion angle should be the same as the driveshaft angle.
What should pinion angle be on lifted truck?
On rear axles with a double cardan-style ‘shaft, the pinion and driveshaft should ideally be at a 0-degree operating angle at ride height.
Can wrong pinion angle cause vibration?
Pinion angle is one of the most important considerations on a lifted vehicle, but sadly it is often overlooked. The wrong angles can lead to horrible drive line vibrations, as well as premature failure of U-joints, driveshafts, pinion bearings and even transfer case output bearings.
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.
Should pinion angle be up or down?
It should be pointing upward towards the front with the vehicle sitting at ride height on a level surface. At least 1-degree and ideally not more than 3-degrees up.
How much angle should a driveshaft have?
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.
What is positive pinion angle?
If the rearend is nose up and its angle is less than the angle of the driveshaft, subtract the rearend angle from the driveshaft angle. For example, if you have a rearend angle of 5 degrees from vertical nose up and the driveshaft is angled up at 3 degrees, you have 2 degrees of positive pinion angle.
Why does the angle of the pinion always change?
The angle constantly changes as the U-joint rotates, causing the driveshaft to speed up and slow down as it rotates. This represents a standard driveshaft setup that is done correctly. Note how the angle of the pinion is paralell with the angle of the transfer case output.
Where does the pinion go on a 4WD?
The pinion should be pointed into the driveshaft rather than paralell with the transfercase output on this type of setup. There are two common types of drive shafts used in 4wd vehicles, standard driveshafts with one U-joint at each end and CV drive shafts. CV stands for Constant Velocity.
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 should pinion angle be on leaf spring?
Currie always strives for 2 degrees of pinion angle on a street car regardless of the type of rear suspension being used. With a leaf springequipped car, the differential movement isnt nearly as controlled as that of a four-link suspension, so more angle may be needed to prevent the U-joint from hyperextending beyond zero degrees under load.
