Tips for Installing MOOG® Compression-Loaded Ball Joints

Designed for Durability

Equipped with a patented integral dust boot and a patented bearing design, MOOG’s compression-loaded ball joints are engineered for strength, durability, long life and easy installation. For the majority of MOOG’s compression-loaded ball joints, use a C-style clamp for easy installation. However, for a handful of parts that are challenging to install, MOOG has developed a new tool to aid in installation. No matter which method you choose to use, follow these helpful installation tips to get the job done right.

Updated Designs for Easy Installation

In the past, MOOG’s compression-loaded ball joints had a step and distinct flange that required the use of an adapter to press it in place. The latest MOOG designs replace the step with a rolled area that can be pressed into the housing. With this design change of the housing and the more robust amount of metal, you can safely press the ball joint into the housing without changing the preload on the stud.

Using a C-Style Clamp

There are several different press tools available, including large and small C-style clamps. When using either size of C-clamp tool, adding a pin and some adapters from a master ball joint press kit to the setup will help you get the ball joint properly installed. Check service manual to make sure you get the right clearances.

Standard Ball Joint Press Setup

A typical cup-style installer is hard to keep on center when you start to push the ball joint in. To maintain a flat surface, instead use an adapter over the housing and a shallow adapter at the other end.

Once everything is set up, tighten the assembly down, center up the pieces so the ball joint is pushed down and straight. Drive it down so the ball joint is flush with the housing.

Large Ball Joint Press Setup

Using a newer style of installer with a larger receiver hole and longer jaw can also benefit from the use of a driver and receiver cups. Attach a small driver to the pin, put a large diameter driver on the rounded surface of the ball joint and place a receiver cup in the bottom of the clamp. Put the upper adapter on and position the C-clamp over everything. Tighten the screw, making sure that everything is straight and drive the assembly until it is flush with the housing.

Using MOOG’s New Installation Tool

In MOOG’s true Problem Solver spirit, it took feedback from the field and developed two new parts to aid in the installation of compression-loaded ball joints. These new parts are designed to be used with specific MOOG ball joints that are challenging to install, but they can be used with any MOOG compression loaded ball joint that features the MOOG patented integral boot.

The new tools work by custom mating to the spin edge giving installers a better landing area for classic press tools. This perfect mate helps to install ball joints straighter and with less risk of slipping off the parts than classical tools have.
