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

Moog Problem Solver K8685
Fleet Vehicle having a rough ride?
Whether you're a driver of police or taxi vehicle, or the everyday driver, when you start to experience shimmying in your front end, extra play in your steering wheel, or uneven tire wear you know it's not good. Here at DST we understand your need to get your ride back on the road as quickly as possible and we're here to help. Moog's part number K8685 is designed for the high demands of the fleet vehicles as well as the daily driver's.


Flaw in the OE Design
The OE design of these ball joints didn't account for the high demands of the fleet vehicles or the demands of daily drivers. Since they didn't account for the demands of these vehicles you often experience premature wear of your ball joint. When this happens the ball joints can actually separate from the housing and cause excessive radial deflection or in other words the side to side movement of the joint in the housing. Once this starts to happen your ball joint can break and that can lead to even more problems and costly repairs.
Moog's Solution
The housing of Moog's ball joint K8685 is made using an advanced metallurgical process, which gives it the superior strength to the OE design. This is what eliminates the excessive lateral deflection in the joint housing. These features were designed with the fleet environment in mind providing a more durable and superior ball joint to the OE design, which also greatly improves the daily driver's vehicle as well.


High Quality Ball Joint
Moog's ball joint K8685 also has a powder metal gusher bearing that, when greased, disperses the grease evenly along the bearing's surface. This makes for a high-quality ball joint for the high demands of these vehicles. Moog part number K8685 also comes with a lifetime warranty that our customer service team here at DST can handle for you should you ever need to replace it. The lifetime warranty helps you buy with the confidence that you'll never have to pay for this part again.

Ive always been an OEM guy.. Until I discovered Moog was better. Case in point, i put these ball joints on an old Lincoln Towncar. Moog actually came in at a lower price than OEM... BUT.. had zerk fittings were original equipment, did not. A no-brainer. The quality is there, the price is there... Im there.

- Question:
- I just purchased a bunch of Moog front end parts and had a question regarding lower ball joints Moog p/n# K8685. These came in box w opened plastic package. I noticed that they had grease in them. Do you normally grease these ball joints? if so what grease are you using? I don't like mixing grease but also have seen others arrive with no or only a small amount of grease. thank you for your time and dependable front end parts!!!
- Answer:
- All Moog greaseable parts are greased after they are assembled. This is to preserve the part while it sets on the shelf. Any good quality grease will be compatible to the grease used in the ball joint after it is assembled.
