Q: Choosing the correct side: right or left?

Axles are designated as “left” or “right” from the point of view of the driver, not from looking at the front of the vehicle. Think of the left as the “driver” side, and the right as the “passenger” side, like an automobile. Take extra care to make sure you’re ordering the correct part.

Q: Finding the VIN

A Vehicle Identification Number (VIN) is a unique 17-character string made out of both letters and numbers that contain a lot of information about that vehicle such as where and when it was made.

Vehicles made at the end of the calendar year are often labeled as being manufactured in the upcoming model year even though the two years use different parts. Split year vehicles also use different parts but are made in the same year. In this case you will need to know the month of the manufacture date. Both these problems are typically not apparent, so a VIN can confirm the exact date of manufacture.

By law, all ATVs and UTVs must be issued a VIN. Every vehicle made or sold in the US since 1971 has one. Its location is different between each OEM but can always be found somewhere permanent. Typically, it is stamped on the frame or a metal plate near the frame.

If you cannot find the VIN, try searching online for the location of the VIN on your vehicle or contact the manufacturer and ask them for its location. If you do contact the manufacturer, it's best to ask them to decode it for you. Possible VIN locations include:

  • Left hand side below the motor, but not on the motor as that is a different serial number
  • Behind the brush guard
  • Behind the air filter
  • On the swingarm bearings
  • Near the A-Arm mounts

Q: Tracking a package

A unique tracking number is generated by our shipping carriers to track your package's status from the warehouse to your shipping address. It is generated after the carrier picks the package up from our warehouse. If you provided an email address, this tracking number will automatically be emailed to you.

To track your package, simply type the tracking number into Google, which will automatically determine the carrier and offer to track your package. You can also determine the carrier based on the tracking number format and visit their respective package tracking page. For convenience, the direct links those pages are listed below as well as a description of each carrier's tracking number format:

  • UPS - 18 characters long starting with "1Z" followed by 16 characters
  • USPS - 22 digit number

If you have not received the tracking number after the package has shipped, feel free to contact us.

Q: What are CV Joints?

A Constant Velocity Joint (CV Joint) is one of the types of joints used on a vehicle's axle. A CV joint is made up of the housing, race, cage, and balls.

Q: Inner / Outer Joints

A CV axle includes two CV joints: the inner and outer joints. The inner joint is the side closest to the differential, whereas the outer joint is the one closest to the wheel. The inner CV joint plunges in and out and is sometimes called the plunging joint. The outer joint does not plunge but rotates around to move with the wheel and suspension.

Q: Differences between Half Shafts, Complete CV axles, and U-Joints

Half Shafts

A half shaft only has the outer CV joint assembled onto an axle shaft. The user then must install their original inner CV joint onto the half shaft to make the part a complete axle. Compare this to a complete CV axle that has both the outer and inner joints fully assembled.

Complete CV axles

A CV axle is located between the wheel and differential, sometimes it is incorrectly called a half shaft or drive shaft. A CV axle includes the inner and outer CV joints completely assembled onto an axle shaft.

Q: U-Joints

U-Joint stands for universal joint. A U-Joint is a “cross” shaped joint that is widely used in driveline applications. U-Joints are usually found on almost all driveshafts and on the inner portion of most older CV axles. U-Joints are also called spider joints.

Q: Female vs. Male Splines on U-Joint Axles

A U-Joint axle has one CV joint on the outboard side and a universal joint and yoke assembly on the inboard side. The u-joint yoke may have male or female-type splines depending on the axle. A male splined U joint will have a splined shaft that goes into the differential. A Female splined U joint will have a splined opening in which a splined shaft from the differential goes into. This illustration compares the two.

Q: What are Driveshafts?

Drive shafts are located between the front and rear differentials, or between the differential and transfer case. Depending on the vehicle, it may have one or two drive shafts. 2x4 vehicles will only have one drive shaft, while 4x4 vehicles will have two. Depending on the publication/outlet, sometimes the axle will be referred to as a “drive shaft”, so please take extra care to confirm what part it is you are looking at.

Q: ATV vs UTV vs SxS

ATV stands for All-Terrain Vehicle. An ATV is always a single rider (some vehicles can have a passenger “seat” behind the driver seat) vehicle that you sit on instead of in. You sit on an ATV like you sit on a motorcycle. A Polaris Sportsman 500 is an example of an ATV.

UTV stands for Utility Vehicle. A UTV is always at minimum a 2-passenger vehicle that you sit in, just like an automobile. You have a driver seat and next to it a passenger seat. Utility vehicles are more work-focused vehicles, usually found on farms and ranches. UTVs typically have a bed on the back or other work-related accessories. A Kawasaki Mule 3010 is an example of a UTV.

SxS stands for Side by Side. An SxS is a passenger vehicle that you sit in, just like an automobile. Side-by-sides can come in 1-, 2-, 4-, and even 6-passenger configurations. An SxS is more of a sport recreational vehicle than a UTV. While both have driver and passenger seats an SxS is more aggressive and sportier. A Can-Am Maverick MAX X3 Turbo is an example of an SxS.
