MOOG parts come greased from the factory, but should also be greased at the time of installation. After installation, MOOG recommends greasing these parts at each oil change for the best service life.
Out of grease? No problem we've got you covered with this Lucas Xtra Heavy Duty Grease tube refill.
Save time, rather than pressing out your old ball joints, replace the whole arm with Moog's value-driven front left upper control arm with pre-installed OE style bushings.

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.
Moog Premium Steering Components carry a Limited Lifetime Warranty. Moog R-Series Control Arms, Hub Assemblies, and Strut Assemblies carry a 3 Year Warranty.
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.
Moog's problem solver ball joint includes a metal gusher bearing and grease-able design for durability and long life.
Moog Problem Solver: Lower Ball Joint K80141
OE Design Flaws in your Aluminium Arm
A selling point to you when buying your Crown Vic or Grand Marquis was its aluminum control arms, right? You wouldn't fool anyone here at DST if you said yes. The OE suspension on this chassis utilizes an aluminum knuckle and control arm which requires a uniquely designed ball joint. In order to prevent damage to the aluminum knuckle, the ball stud taper on the OE ball joint doesn't wedge into the receptacle like a common ball joint. Instead, the ball joint uses a steep taper cone and a Belleville washer locknut to keep the ball joint securely in place. Also, the taper cone, housing, and washer are coated to prevent galvanic corrosion which happens when uncoated steel comes in contact with aluminum.
OE Replacement Design Requirements
That being said, it is very important to select a replacement ball joint that follows these strict OE design criterion. Otherwise, you won't be getting the proper function or longevity. There are many suppliers who claim to have a good OE replacement, but you need to make sure they aren't offering parts that:
- Utilize a taper cone, housing and nut that are uncoated
- Provide a taper cone as a separate piece making installation very difficult
- Use a flange nut instead of the required Belleville washer nut (the flange nut can loosen during service, resulting in ball joint separation or the stud breaking
Problem Solving Engineering
Moog's problem solver line has a solution for you. Moog's problem solver parts target factory defects or poor original design, replacing them with a better more durable part. The K80141 is a lower ball joint for a 2003-2011 Ford Crown Victoria and Mercury Grand Marquis. Moog's problem solver ball joint includes a metal gusher bearing and grease-able design for durability and long life. The forged housing, unlike other OE replacements, is coated to prevent that galvanic corrosion that is common in an aluminum control arm.
Other Problem Solving Features
Also included in the K80141 is a built-in, and coated, taper cone allowing for easy operation. The supplied locknut features an OE-style Belleville washer for secure installation. And just like the rest of the pieces, the nut and washer are coated to guard against corrosion. Moog includes a very steep taper with this ball joint, taking a lot of the stress off of the aluminum arm.
