Quick Answer

You Asked How do you tell the difference between 1310 and 1350 U-joint?

Size and strength. The 1310 series joint is what you would expect to find stock in most Jeep or small trucks. A 1350 series joint/shaft is what you might find in many full size trucks. While it’s not 100% accurate, you could say that a 1310 is a “half ton” joint and a 1350 is a “one ton joint”.

How strong is a 1310 U-joint?

Most racers upgrade to the bigger 1350 U-joints for more strength. According to Spicer, the 1310 joint is rated at 400 lb-ft of continuous torque (down the track) and 800 lb-ft of short-term torque (launch at the line). The 1330 has the same size caps as the 1310, but the U-joint cross is the same size as a 1350.

What does a 1310 U-joint fit?

This allows you to mate a larger (or smaller) U-joint to the other. For example, you buy a new driveshaft that comes with 1350 weld-in yokes, but your car has 1310-sized yokes for the transmission and rear differential.U-Joint Sizes.

Series Width Cap Diameter

How much torque can a 1350 u-joint handle?

The 1350 U-joint is rated for 2,200 lb-ft (minimum elastic limit) of torque.

Do they make U-joints with different size caps?

Yes they do sell Ujoints with different size caps on each end. I had to use one when I bought a different driveshaft for a 1984 chevy truck that I had.

Are CV joints better than U joints?

A constant velocity (CV) joint does essentially the same thing as a U-joint, only better.

What is the difference between a 1350 and 1410 U-joint?

1350 joints are found in 1-ton trucks and use the wider body of the 1330 joint but with larger trunnions and caps. 1410 joints use a wider body but the same-size caps as a 1350 joint, making them perfect for high-horsepower, high-angle applications.

How much power can an aluminum driveshaft handle?

An aluminum driveshaft will support up to 900 lb-ft or 900 to 1,000 hp, making it a great lightweight choice for most muscle cars. However, it is not as strong as steel, so some custom driveshaft shops do not have twist guarantees on aluminum driveshafts.

How do I know what size U joint I have?

You will need to measure from the edge of one snap ring groove straight across to the edge of the other snap ring groove. For U-joints with outside snap rings, you will need to measure from the edge of one u-joint cap straight across to the edge of the other u-joint cap.

How do you identify universal joints?

How to measure yokes and u joints

What happens when u joint fails?

A bad u-joint can cause a clunking sound or jerkiness while driving, particularly when letting off of and pressing the accelerator. A bad u-joint can also cause vibration at certain speeds, emanating from the center or rear of the vehicle.

What is a 1350 yoke?

The forged 1350 steel pinion yokes are designed for Spicer 1350 series universal joints, forged for maximum strength, precision machined, heat treated for toughness, built with U-joint-style joint retainers, and available with the appropriate nuts, washers and u-bolt.

What is a 1344 u-joint?

QU40758 Greaseable S44, AAM 1344, or 3R Series Driveshaft Universal Joint for many Dodge and General Motors front or rear driveshafts from the mid 1970’s to current. QU40758 is a hot-forged, alloy steel, greaseable u-joint with nitrile rubber seals. You will find this u-joint used in both CV and non CV applications.

Where is Spicer made?

Spicer incorporated the Spicer Universal Joint Manufacturing Company in May 1905, shortening the name to Spicer Manufacturing Company in 1909. In 1910, the company relocated to a site adjacent to the Lehigh Valley Railroad and Bound Brook in South Plainfield, New Jersey.

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.

Do all u-joints have snap rings?

After a little more research, I found out that aftermarket u-joints do not come with selective snap rings! I had always purchased aftermarket u-joints. As it turns out, all u-joints are not equal.

What does the U in U-joint stand for?

Universal joints allow drive shafts to move up and down with the suspension while the shaft is moving so power can be transmitted when the drive shaft isn’t in a straight line between the transmission and drive wheels. Rear-wheel-drive vehicles have universal joints (or U-joints) at both ends of the drive shaft.

Why is it called a universal joint?

The term universal joint was used in the 18th century and was in common use in the 19th century. Edmund Morewood’s 1844 patent for a metal coating machine called for a universal joint, by that name, to accommodate small alignment errors between the engine and rolling mill shafts.

Are U-joints and ball joints the same?

A universal joint is like two perpedicular hinges gunged together… so anything connected to it can move to point in any direction, but can’t rotate (I’m not sure if that’s the right word for it). A ball joint is effectively the same, but the object can rotate.

What is a double cardan u-joint?

Double Cardan is a term used when describing a one-piece driveshaft with three (or more) universal joints.

Why is there a double cardan driveshaft?

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 series is a 369 u-joint?

Fitment U-Joint moog-369 fits these vehicles: AMC Ambassador 1967 thru 1974. AMC American 1968 thru 1968. AMC AMX 1968 thru 1980.

Is an aluminum driveshaft worth it?

The Advantages

Typically, switching to an aluminum shaft will mean reducing the weight by anywhere from 10 to 20 pounds. This decrease in weight benefits the engine as well, as weight is magnified when it needs to rotate, just as driveshafts do. The less weight that needs to be rotated, the easier it is on your engine.

What is a common cause of torque related driveline vibrations?

One of the most common cause of driveline vibration are worn U-joints or slip splines, out-of-balance components, yokes out of phase or misaligned angles, approaching critical speed range, and yoke ears that are not concentric with the splines.

What does an upgraded driveshaft do?

Upgraded aftermarket driveshafts have the extra length, and strength, needed to accommodate these changes. Another reason to upgrade your driveshafts doesn’t have to do with lift kits at all, but engine power.
