Performance Parts / Replacement Parts

The driveline encompasses all the components that take power from the transmission and send it to the wheels that drive your car or truck. This includes driveshafts, axles, CV-joints and U-joints, transfer cases, differentials, and wheel hubs. Driveline parts are generally stout enough to last if the vehicle isn’t abused, but if you hear clunking and whining and feel vibration, you may need to check out our selection of driveline replacement parts.

Front wheel drive axles are also known as “halfshafts”. These shafts transfer power from the transaxle to the wheels, and because they must deal with steering as well as suspension movement, couplings that can handle greater angles are needed, called CV-joints. There are several kinds of CV-joints but all are housed in flexible boots packed with grease. It is this boot that commonly fails. Once the boot breaks, the lubricant is lost and the CV-joint usually fails shortly afterward. We can supply you with your choice of repair solutions, from replacement boots, to joint and boot kits, to complete axle assemblies.

The differential takes the power from the driveshaft and transfers it to the wheels via axle shafts. The driveshaft is connected to a pinion gear, which drives a ring gear attached to the differential case. The case contains pinion gears, and side gears splined to axle shafts that together allow the wheels to turn at different speeds when turning a corner. Differentials are generally durable components, but the bearings on which the pinion and differential case rotate can wear causing noise and clearance problems. We can supply all your repair needs including rebuild kits, case assemblies, and ring and pinion sets.

Wheel hubs are the interface between the drive axle and the wheel. The hub is splined to the axle shaft and has a flange with studs to which the wheel is attached. The hub bearings are the common wear parts. When worn you may hear a growling or humming noise that may go away when you turn the steering wheel back and forth while driving. Older hub bearings had to be removed and installed with a press and fixtures, but most new vehicles have unitized hubs that are replaced as an assembly. Regardless of the vehicle or type of hub, we have the replacement parts to make your vehicle quiet and safe again.

    Wheel Bearings: Descriptions of Bearings, Races, Seals, and Hubs
    Wheel bearings are as old and important as the wheel itself thanks to their ability to allow free rotation without the damaging effects of friction and wear. In this article, we’ll define and discuss the individual components so that you are better informed when you are ready to purchase replacement wheel bearings, hubs, seals, and components. We’ll also cover the differences between “wheel bearings” or “axle bearings” mounted at the wheel itself along with “axle shaft bearings” located further inboard along axle shafts. “Bearings” are actually the small round pieces that spin within a bearing assembly. Even though bearings come in a variety of shapes, they all serve the same basic purpose.

    The Difference Between A Transaxle And A Transmission
    In this article we'll look at the differences between a "transaxle" and a "transmission". In short, a transaxle performs both the gear-changing function of a transmission and the power-splitting ability of an axle differential in one integrated unit. A transmission performs the gear-changing function only, delivering power via a single output shaft at the back of the unit. Although both perform gear shifts in the same fashion, there's often confusion about these two terms because the word "transmission" is sometimes used as a blanket description to include transaxles when it should not be.

    Auto Parts: Dealer vs. Aftermarket
    The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.

This part isn't visible to the eye, however very easy to install.
