What is proper driveshaft angle?

Table of Contents

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 angle should a rear end be?

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).

Why is there a double cardan driveshaft?

Some drivelines use a “double cardan,” or constant velocity (CV), with two joints at one end (typically the transfer case) and a single joint at the other end. The two joints split the angle, allowing for greater angularity. With this type of driveline the pinion should be pointed up at the transfer case.

What is the max angle for AU joint?

Universal joints have several unique features that make them ideal for a variety of applications. Most significant is the ability of the universal joint to operate at high misalignment angles. Operating angles up to 15 degrees are not uncommon.

Do universal joints work at 90 degrees?

It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint.

How do I choose a drive shaft?

There are many factors to be considered when selecting a driveshaft. They include the type of shaft material, diameter, thickness and length, yokes, and U-joints that are properly rated for the task at hand.

How thick are drive shafts?

According to Raymond, the common driveshaft thickness is . 083-inch wall, so despite what we know about chassis tubing where chromoly is stronger and can therefore be thinner, driveshaft tubing is produced at a more standard thickness due to these critical manufacturing tolerances.

How much angle is to much for a drive shaft?

There’s not too much of an angle, roughly 2 degrees on each end, but still enough of an angle to keep things running smoothly. Measuring Angles. One of the things we wanted to get cleared up with Dick is when to start considering your driveline angle and the resulting driveshaft operating angles. When to measure, and how to measure are crucial.

How to measure driveshaft angle?

Place the unit on the first slope (Slope A) and allow the reading to stabilize approximately 10 seconds.

Push the “Alt Zero” button.

The display will read 0.0° and the “Alt Zero” button indicator will flash.

Move the unit to the next adjacent slope (Slope B).

What is good operating angle for drive shafts?

– Suspension changes caused by: worn bushings in the spring hangers, worn bushings in the torque rods incorrect airbag height – Revisions in components of the driveline – Stretching or shortening the chassis – Adding an auxiliary transmission or transfer case in the main driveline – Worn engine mounts – Raising or lowering of the vehicle

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 pinion angle affect traction?

A wrong pinion angle that binds things up will cause traction problems and if the angle is changed so that it would relieve the binding then that would actually change the way the cars hooks, but that is the only case where a pinion change with out changing anything to do with the suspension would have any affect.

How does pinion angle affect suspension?

Two degrees of pinion angle on a street car—regardless of the type of rear suspension being used, is the norm. This can lead to binding of the u-joints as the suspension reacts, and will hurt traction. To check the pinion angle, the vehicle needs to be sitting with its weight on the tires, at normal ride height.

Does ride height affect pinion angle?

The operating angles do change when the rear suspension is lowered or raised. This is because the position of the pinion relative to the transmission changes. Changing front ride height or installing taller or shorter tires, front or rear has zero effect on the operating angles.

Can you explain how to set and adjust pinion angle?

Single Carden Driveshafts -. Measure the angle on the transmission yoke (or flange),and set the pinion angle on the axle 1*- 2*degrees lower.

Double Carden Driveshaft -.

Driveshaft Angles -.

U-Joint Angles -.

Pinion Angles (SIngle Carden Driveshaft) -.

What is proper drive shaft angle?

How to measure drive shaft angles?

Begin by putting the weight of the vehicle on its springs.

Then push your transmission yoke all the way into the transmission.

Next,back it ¾” to 1” (or to your desired running position).

Now take your measuring tape and measure from the center of the U-joint cap hole in the slip yoke to the center of where the bearing attaches to the frame.

How to determine correct pinion angle?

Place an angle finder on the bearing cap and take note of the reading.

Rotate the driveshaft 90° and repeat step one.

Find the difference between the two readings and this will be that u-joint’s working angle.
