  • Moog fulfills their warranty through their individual dealers. That means that in order to receive warranty support, you will have to refer back to the original dealer you purchased the part from. Be sure to check the dealer's warranty support before you buy the part to make sure that they will properly support the warranty. If a dealer will only refer you back to the manufacturer in order to receive warranty support, then you may not actually have any warranty at all.

    Part of our warranty process includes reviewing evidence of the defect provided by the customer. This is easily accomplished by providing video or images of the defective part so our staff can verify the claim and move forward with the warranty process. This removes the necessity of shipping the part back to our facility at the customer's expense.

    WARRANTY:

    Moog Premium Steering Components carry a Limited Lifetime Warranty. Moog R-Series Control Arms, Hub Assemblies, and Knuckle Assemblies carry a 3 Year or 36,000 mile Warranty (whichever occurs first). And Moog CV Axles carry a 2 Year Warranty. Above warranties are based on customers who own a car, van, SUV or light truck (less than 8,000 lbs. or 3,625 kilograms).

    Moog warranties their parts to be free of defects in materials and/or workmanship during these timeframes as measured from the date of purchase.

    If a Moog part should fail due to materials or manufacturing defect while under warranty, we will provide a replacement of the part upon return of the defective part.

    Limited to ONE replacement during guarantee period

    Wearable RUBBER parts are not covered under warranty (Dust boots, bushings, bump stops, etc.)

Moog Control Arm Bushings

Controlling Comfort and Steering

If your vehicle is suffering from early tire wear, handling issues, or loud noises under the chassis, you could be dealing with worn OE control arm bushings. Designed to attach the steering knuckle and wheel assembly to the vehicle, your control arms are a crucial part of your steering system. The bushings themselves absorb impacts from the road, smoothing and quieting your ride.

Worn Rubber Bushing

Long-Term Performance and Long-Term Coverage

Moog crafts each of their bushings to either meet or exceed OE specifications. While the OE bushings might sag or rot away, Moog's control arm bushings are there for the long haul. Moog backs this up by covering all of their control arm bushings with a lifetime warranty handled in-house here at DST.
