It would be interesting to know.
May be if there is no sign of too much play or other wear and tear one could say if it aint broken don't fix it.
Gavin, Trapeziums do not need services, only care.
However, if you feel there is some play or you want peace of mind, google Trapezium Developments in Roodepoort, they will be glad to assist in any way.

Gavin you said it. Put ur mind at rest. Although good we should sometimes not worry about things that can go wrong until it happens. Earlier in the week I stumbled upon the thread on thrust bearings on the jacks. After I serviced my 4 jacks I asked myself if there is no damage to the threads then they should work effortless. I found I could turn all of them by merely having a long socket on the wurm head.
This means by modifying to add thrust bearing is perhaps something we do because we CAN and the effort would be less but not something worth the effort to change.
Please guys don't stone me it is just myself thinking a bit.
Glad you are sorted, at least, now you know from the manufacturer what is acceptable.
I was looking at the forum to see if there is any spec on the trapezium since I have had mine also for approximately 12 years, never needed servicing, but also not knowing what the spec should be, thanks to the forum we are now informed.
However fate decided for me in that the one bottom bush on the right were lost during my recent tow. I am now in search of the so called famous Trapezium developments but the phones does not work, the E-mail does not get responded to, does anyone knows if they still exist, moved or have they just like many good companies disappeared.
If so would anybody know were I could source spare parts for this highly effective stabilizer, or get the unit serviced?
