TO SUMMARISE FEATURES:
Is your pintle ring suffering excessive wear and tear? Your trailer may have its tandem spring setup in the wrong location.
Equipment installed in the wrong location can have a tragic effect.
All trailers have different weights and lengths. Heavy loads must ensure even distribution across your axle load group.
Buy a set of tow ball scales and measure your pintle hook head weight. It must be within the 5% to 7% range for a tandem trailer.
Why are tow ball scales important? Read here.
Without a tow ball scale, the head weight of your coupler is guesswork.
DIY is great but only if you are sure of the installation techniques.
