Can painted trucks/flaws in the paint be a significant cause of pivot issues? I’ve got a pair of Thunder 151 Teams with black powder coated hangers. Last pair of non-raw trucks I owned were Trackers on my first board about thirty years ago so I have pretty limited experience with how they may break-in differently than raw/polished.
When I first set these up, the hangers were super stiff in the pivots. Ridiculously creaky, occasionally with a pronounced “click” when tilting past center-point. First, just to make sure it was the pivot, I swapped out the stock glow-in-the-dark bushings (I know. I got these bad boys on clearance) for some stock thunders off a pair of 149s, then Bones mediums, and then, most recently, some Thunder blue 95 bushings from a truck rebuild kit. The issues persist regardless of the bushings. Wax shavings or speed cream in the pivot cups helps for about ten min but they still feel a little jittery as they lean and then the squawk comes back fully.
I swapped the stock pivot cups with Thunder replacements from one of the truck rebuild kits and there is no difference ultimately. Before I get into non-Thunder pivot cup replacements, I’m curious if anyone has thoughts on what’s going on with the powder coating on the pivots and if they’re just going to perpetuate the issue regardless of what pivot cup bushing is in there: (These are two sides of one hanger pivot)
The wear on the end of the pivot began first, the stuff on the sides has developed more recently. It’s apparent to me that the cups are being compressed enough to allow metal to metal contact on hard turns; the lip of the pivot cup bushings are flush with the baseplate.
Should I try to strip the paint from the pivot of the hanger to see if just smoothing out that surface helps? Will a harder pivot cup bushing solve some of this perhaps? (I’m like 210ish lbs so I know I’m part of the problem.)
For reference, my best-feeling truck setup right now is a pair of polished Thunder 149s with stock pivot cups, Thunder 100a hard black bushings w/ stock washers. Kingpin nuts are usually flush on back and a little looser than flush on fronts.
Any advice would be greatly appreciated.
