Rubber is chosen for isolation, not for location — it is soft on purpose.\u003c\/p\u003e\n\u003cp\u003eThat is fine on pavement. Put real load into the rear end and the bushings compress, the axle moves relative to where the chassis thinks it is, and the truck starts to feel like it is steering from the back. Under hard acceleration the same compliance shows up as wheel hop.\u003c\/p\u003e\n\u003cp\u003eA machined billet arm is one piece with no seams and material placed where the load actually is, and the uniball gives the arm a defined pivot instead of a squishy one.

Tighter and more direct than an elastomeric joint, and the uniball itself is a replaceable wear item rather than something that scraps the arm.
