Hi,
on our recent Lap Around Victoria I managed to have a moment, that if it had happened a few seconds later would have been quite a different outcome, caused by a steering arm breaking. It was a hairy ride for a little bit until the Moke came to a stop. There was a lot the that happened to find a replacement and get going again which took up pretty much the whole day that I will share elsewhere.
This is the broken steering arm that normally connects the steering rack to the swivel hub. You can see from the break that the there are shiny bits and darker rusted bits in the cross section which indicates there has been a fracture in there for sometime before the eventual failure.
As for a potential cause there was one idea put forward that it is caused by the common type of ball joint breaker being struck with a hammer which has merit. I have only seen two other arms fail on Mokes and if we exclude the Moke that drove into a rock wall heading up to the Lookout at Tamworth the other one was on a similar corrugated outback road,not the road itself, but potentially the amount of driving on outback roads each Moke has done.
While others went ahead to find a replacement arm this bush mechanic fix was quite impressive not just in that it managed to do 30km on a rough corrugated road but by the number of people that provided from their own experiences the different ideas that eventual became this splint. The nut on the tie rod end was removed and the bolt on the swivel hub was loosened and a piece of fencing wire was looped around each end. A 10mm spanner was then slipped over the tie rod end and the nut fitted, the fencing wire was then twisted and the nut tightened to pull it all together. Then four hose clamps were used to hold it all together.
An unpredictable thing to drive, ending up off the edge of the road more than a few times, but it did the job to get us much closer to the highway for the fitting of the replacement arm.
