GSP CV Axles

March 17, 2022 through the end of March 2022, GSP is offering RockAuto customers an exclusive 10% instant manufacturer rebate on their entire selection of CV Axles. Since 1985, GSP has been a leading manufacturer of automotive driveline parts. Their CV Axles incorporate premium-grade materials, undergo rigorous quality-control testing, and are made to OE specifications for precise fit, form and function.

CV Axles, or constant velocity axles, transfer power from a vehicle's transmission to the wheels. This allows the vehicle's suspension to articulate and the front wheels to turn. It is important to know the symptoms of CV Axle wear to ensure safe vehicle operation and maintenance. Common symptoms include:

  • Clicking sounds when turning
  • Excessive wheel / steering vibrations
  • Grease on wheel / suspension components


Whether you drive a 2008 Chevrolet Silverado 1500, a 2013 Nissan Rogue, or a 1997 Honda Civic, RockAuto has CV Axles for your vehicle in the "Drivetrain" category of the catalog. Simply add a GSP CV Axle to your cart to instantly save 10% on RockAuto's reliably low prices. Do not delay, this offer ends March 31st, 2022!

Repair Mistakes & Blunders
Repair Mistakes & Blunders

As a college student in Colorado back in the 1970s, I was very much into cars and became somewhat of a "shade tree mechanic." My dad had a friend who owned an AMC Gremlin and he relayed that the red "brake" light on the Gremlin's dash just came on. Having just replaced the brake master cylinder on my car which had the same symptom, and with no further research into what may have happened, I confidently offered to replace the master cylinder on the Gremlin. Funny thing though, with the new master cylinder, bleeding the brakes did not result in a firm pedal and that light stayed on!

That is when I started asking questions. I learned that the light came on after they hit a big pothole. I pulled the left front wheel to find the impact had dislodged the brake shoes which allowed the wheel cylinder to simply expand unabated and the resultant pressure differential from front to rear set off the warning light. Lesson learned; take the time to get the whole story.

Do Not Wait Until Your Rear End Starts Sagging
Tom's Story

Do not wait until your rear end starts sagging to learn how your vehicle's air suspension works. Everything from late-model Jeeps to Teslas may have an "air suspension" pressurized by an Air Compressor, but system design and components differ significantly between models, option packages and model years. Inspecting your vehicle's particular suspension and looking at the replacement parts available for it under "Suspension" in the catalog will help you understand what maintenance is possible and what repair options are available. They all help improve vehicle ride height and ride quality, so the words are often used interchangeably, but there are actually major differences between air shocks, springs and struts:

Air shocks, springs, struts and conversion kit
Top to bottom: Air Shocks, Air Spring,
Air Strut, and Conversion Kit

Air Shocks replace conventional rear shock absorbers either as an aftermarket upgrade (ex/ 20-year-old Dodge Grand Caravan) or original equipment (ex/ 10-year-old Cadillac Escalade). Vehicles with rear air shocks usually have conventional steel springs. The air pressure in the shock absorber is adjusted by the driver and/or computer to better maintain ride height and comfort when the vehicle is loaded. (Air shocks are typically included with "adjustable" shock absorbers for specific vehicles in the catalog.)

Air Springs replace conventional steel springs with OE air spring bladders (ex/ Lincoln Town Car and five-year-old RAM pickups). Air springs may even improve the ride of an empty truck by reducing jouncing. The vehicle usually still has conventional shock absorbers that should be replaced as part of routine maintenance (usually after 50,000 miles (80,000 km)) to help maximize the life of the air springs and other suspension parts as well as restore braking, handling and ride.

Air Strut is just "Strut" in the catalog because like a conventional hydraulic strut, they do the job of spring and shock absorber while also providing suspension structure. Air pressure in individual struts can often be adjusted independently by the computer to optimize handling, braking and ride. They tend to be relatively expensive since they fill so many roles in the suspension system. The Tesla S and newer high-end SUVs, trucks and cars frequently have air struts.

Suspension Conversion Kits are also available under "Suspension" for many vehicles in the catalog to help customers who want to replace an air suspension with conventional hydraulic shocks/struts and steel springs. A suspension conversion kit can cost many hundreds of dollars less than replacing leaking/failing air struts, air compressor, etc. The kits also provide a solution if replacement air suspension parts are no longer available. Some owners just prefer hydraulic instead of air suspension because of their driving style or how they use their vehicle; make that luxurious Lincoln handle more like a Police Interceptor!

David's 1997 BMW 528i
David's 1997 BMW 528i

This is my 1997 BMW 528i. I bought it April of 2020 to use as a daily driver while performing some extensive work on my other car, but I learned very quickly that a 1990s BMW might not have been the best choice for daily reliability. I have since replaced rear axles, rear shocks, driveshaft mounts/joints, pretty much everything for the steering system (reservoir, fluid lines, rack rebuild kit, tie rods, boots), oil pan gasket, valve cover gasket, oil filter housing gasket, timing cover gasket, several cooling hoses, and a plethora of various seals and bearings to keep this thing functional.

I love it. My wife hates it. It is a perfect car and well on its way to being the reigning RockAuto parts champion in my driveway.
