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 aluminium control arms right? You wouldn't fool anyone here at DST if you said yes. The OE suspension on this chassis utilizes an aluminium knuckle and control arm which requires a uniquely designed ball joint. In order to prevent damage to the aluminium 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 aluminium.
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
With all of these specific requirements, you need a part that can solve these corrosion, failure and installation problems.
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 aluminium 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 aluminium arm.
