Got blue 92s and now my mindys feel great. Started noticing that they were loosening on their own. Idk if any ones posted this already but has anyone tried the dooks shock pads? Wondering if that would help absorb all the rattling that’s making them loosen up.
The loosening on their own is more due to the kingpin shaft moving every time you lean left or right, eg crooks, slappy or other hard movement tricks tend to make the kingpin move more than other more gentle skating.
What I have recommended is tighten the inverted kingpin right down until it cannot go in any more. It is not that far as the threads on the Indy kingpins are not very long anyway, but when it is right in at what I have called "full lock" then the kingpin doesn't move half as much as when it is anywhere else.
The more you loosen the trucks off from the full lock position, the more likely the kignpin will continue to move, which has then been discussed and even quite a few people putting in complaints or claims to NHS who distribute Indy who often don't reply with anything useful, or have said "Just use locktite" or something, as people on here have said in the past.
Using shock pads or similar things will lessen the vibrations through the deck but I don't think they will help much at all with the known issue of the kiingpin loosening off by itself.
It is a frustrating issue though, so trying anything and everything, as per the last 25 pages, you could see if any trial and error methods do work, which would always be welcomed here too.
Given some bushings will work better than others, in any normal kingpin trucks, you can adust the nut minimally here or there to get things just right, but with the inverted kingpin, it is harder to figure that out, often to the detriment of the kingpin loosening on its own or when you don't have it down as far, then you have less clearance as well.
See how much off full lock you have it and as the bushings wear in, you might find that they work well in full lock, so you might not have half as many issues with the kingpin moving.
Those blue bushings are good ones too - had the 92 duro bushings in my trucks for a long time.
* Replied before seeing we had talked about this before, but I am curious to hear how many turns out you are anyway.
