Took the RV out for the after sway bar installation test run. Heard the dreaded clunk on the first short run. I was making some fairly aggressive 90 degree turns when they occurred. Looked things over and took her out again.
30 miles of back roads, lots of turns and bumps with no clunk. Took her back through the same turns where I first heard the noise and no more clunk.
I did notice that the bar had shifted slightly in the "U" brackets from side to side finding its own center.
Maybe all it takes is a little breaking in for the bushing to settle down.
I am well pleased with the performance of the bar. Much more stable in turns and on uneven roads. Well worth the investment.
Being passed by large trucks is yet to be determined.
