The bolts sheared off, the drum fell on the inside of the rim and gouged it deeply, the rim sheared and took off... Just felt a bump, the car's rear swerved wildly for a few seconds (I first thought that the trailer had a puncture or a problem with a wheel), then a long screeeeech and the wheel overtook us as I was steering the whole thing to the berm.
Now, here comes the African miracle: that was 3pm, 50km from Kampala, having left the extreme North East of the country a day earlier. Our original plan was to reach town, have a shower, and head for the Swiss Consulate for the National Day party. Obviously, the plan's timeline was going to be revised...
I made a few calls, got the number of the right guy with the right parts, and got my driver in town to go and fetch another car, the parts and a "fundi" (closest thing to a mechanic around here). By 6pm everything and everybody was on location and we were on our way to town with the second car and the trailer. We changed clothes on the fly in the car, and arrived just an hour or so late - which is being pretty punctual by local standards.
And when we reached home by 11pm, the Cruiser was in the yard, fixed.
Try that in Europe...!
