This thread isn't about your radius rods or a sprint car, it's about adjustable strut rods on a Mopar. I frankly don't care what your sprint car does, it's not relevant.
After 70k miles of street use the strut rods on my Challenger still don't make any noise. Over 30k miles on my Duster, no noise at all from the strut rods. And it's not because I'm deaf, I hear the spring sliders on the rear of my Duster clicking occasionally. And I could hear the heims on the UCA's of my Challenger clicking when they wore out.
The adjustable strut rods on these cars shouldn't make any noise. If they are, the heims are worn out and need replaced.
Are you sure it's the strut rods? If you have installed poly LCA bushings you may need to lubricate them better. What did you install with the suspension rebuild?
