[DML] Re: Modified Trailing Arms For 1/2" Bolts

Actuator arms on C Band satellite dishes used HEIM joints for several decades. That's where I first encountered them.

Since a car is built to a certain price-point to satisfy a market niche you cannot over-engineer it. You almost never see Heim joints in cars. They show up mostly in race cars and aircraft. The rubber bushing is supposed to be compliant and absorb the bending stresses. As we all know it can but only up to a point. Besides, the rubber joint would isolate the frame from the trailing arm better than a Heim joint and not transmit vibration and road noise. Too bad they used a split bushing tube inside. If they went with a welded tube with a thicker wall it would have held up better.
