Went to the Park it in the Market event at Greenwich market this evening.
I spoke to Stuart from Krazyhorse, who further enlightened me on the events that lead to the poly inserts failing. The main reason is the amount of heat build up in the coupling and not the quality of the inserts.
John.
Thanks for that John. I will try to monitor temperature through the gap where the steering rack passes. I wonder if the temperature build up is due to the round inserts moving about so much and causing heat by friction?
