Gentlemen the Husqvarna NZTR pivots are repairable. They have replaceable bushings. Like most of us I have been just replacing the these but lately I ran into trouble as they are staying on extended b/o everytime I order them from my distributor. So I decided just to try installing bronze bushings. Well this when I found they already had bushings installed. So much easier to install the correct bushings.
Well It took me a month to get in the correct bushings from a supplier but they do fit as well as the original bushings. The original bushings are TSI10PT16Z and I am using 10TH16 bushings. Replacement cost nearly a third of the RH pivot and even less on the LH pivot as it is twice the cost. Now I'm referring to my cost of S4.28 including shipping for the bushings which I change the customer 6.58 each (13.16/ pr) which a lot less than the $46 retail for both pivots.
