# How do you adjust driveline angles?

## How do you adjust driveline angles?

Place a spirit level protractor on the driveshaft about halfway between the transmission and the Differential. Read and record the angle shown on the protractor scale and note whether the driveshaft points up or down at the front. Record the angle as “3 degrees up” or “2 degrees down,”etc.

What is the recommended operating angle of a single cardan U joint?

The number one rule of single cardan or u-joints is the sum of all the operating angles of all the u-joints in a shaft must equal to 0°.

### What is an acceptable driveline angle?

Driveline angles should be equal to or within 1° of each other. When checking driveshaft angles, be sure all tires are inflated to their normal operating pressure.

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 the operating angle of a double Cardan joint?

Since there are two joints, the operating anglecapacity of the double cardan joint is twice that of a single cardanjoint. These are the type of CV joints most commonly used on driveshafts connecting a transmission or transfer case to a rear or front axle.

What is the you joint operating angle on a driveline?

U-joint Operating Angle: This is the angle formed between the two yokes connected by a cross and bearings. It may be a simple or compound angle, depending on the geometry of the driveshaft.

## Which is better a double Cardan or single cardan drive shaft?

Many people mistakenly believe that a double cardan or C.V. type drive shaft will allow for greater operating angles than a conventional two joint or single cardan drive shaft. This is not true.

How do you measure the angle of a driveline?

Place a spirit level protractor on the driveshaft about halfway between the transmission and the Differential. Read and record the angle shown on the protractor scale and note whether the driveshaft points up or down at the front. Record the angle as “3 degrees up” or “2 degrees down,”etc.
