RGX100970 Watts Linkage Bar Bush Discovery 2 L318

The Discovery 2 L318 is one of the few production vehicles ever to use a Watts linkage as part of its rear suspension geometry, and it is one of the features that makes the platform uniquely capable at controlling rear axle location under load. The RGX100970 is the outer Watts linkage bar bush, the rubber insert that sits within the transverse link eye of the rear Watts linkage assembly. This bush serves as the primary wear interface between the linkage bar and its mounting point, absorbing lateral forces, dampening road vibration, and maintaining precise axle tracking as the suspension cycles. When these bushes wear out, the rear axle begins to move laterally under load, producing handling vagueness, clunking over bumps, and accelerated wear in surrounding suspension components.

This listing offers the RGX100970 bush available as a single unit or as a set of two, giving you the flexibility to replace one side or address both transverse links in a single order. Since the Watts linkage uses two outer bushes, one at each end of the transverse bar, ordering a set of two is recommended when carrying out a thorough suspension refresh.

The bush is a press-fit component, meaning it is designed to be pressed into the linkage eye using a hydraulic press or appropriate bush pressing tool. Attempting to install or remove this bush without proper press equipment can result in damage to the linkage eye or incomplete seating of the bush.

FAQ

Do I need one bush or two to complete a full Watts linkage outer bush replacement?

The Watts linkage on the Discovery 2 L318 uses two outer bar bushes, one at each end of the transverse link. This listing offers the option to purchase a single bush or a set of two. For a complete outer bush replacement on one transverse link, two bushes are required. Ordering the set of two ensures you have everything needed in one go and avoids the need for a second order mid-repair.

Is this a press-fit bush, and can it be installed at home without a hydraulic press?

Yes, the RGX100970 is a press-fit bush and requires a hydraulic press or dedicated bush pressing tool for proper installation and removal. Attempting to drive the bush in or out without correct tooling is likely to damage the linkage eye or leave the bush improperly seated, which can affect handling and cause premature failure. 

What symptoms indicate that the Watts linkage outer bushes need replacing on a Discovery 2?

The most common signs of worn RGX100970 bushes are a clunking or knocking sound from the rear suspension over bumps or during cornering, a vague or wandering feel in the steering at highway speeds, and visible deterioration or cracking of the rubber bush material on inspection. Because the Watts linkage is responsible for controlling lateral rear axle movement, worn outer bushes allow the axle to shift side to side under load, which directly affects handling stability and can accelerate wear in other rear suspension components.
