New shocks went onto the front axle today.
We have been experiencing a bouncy ride (up and down).
Gillig part number 53-35885-000N which is Koni part number 881458SP2
This is an adjustable shock
How to adjust Koni shock
The problem is neither Koni or Gillig could tell me what the adjustment should be. Koni suggested it should be full soft and then go from there, (if not happy take it back off and adjust it firmer).
When the old shocks were removed I was unable to find what they were adjusted at, the adjustment mechanizem seem broken (these were stock replacement shocks). The old ones were shot! Next to no damping of movement.
I took a stab at it and went full firm and then backed off on full rotation and then enough to line the mounts up. (firm is clockwise) There are about five full rotations of adjustment.
I have been on a short highway test drive and the ride seems much better.
