I had several Morris Minors in my youth.

The front suspension wheel supports consist of vertical steel castings (a long kingpin) with a threaded top. A sort of brass or bronze trunnion fits onto the threaded part allowing the wheels to pivot.

This type of suspension is notorious for failure but not quite as you might expect. Even with regular greasing, microscopic fragments of steel get embedded in the brass and then work abrasively on the threaded steel casting. On failure, the brass trunnion appears to be in perfect condition, but the steel threads on the top of the  kingpin itself are almost completely worn away. Trunnion pops off, wheel collapses..... ! It wasn't just Morris Minors. 40 years ago cars at the roadside with front wheels at strange angles were a common sight!

King Pins, Links, and Trunnions, OH MY!

Of all the people I have come to know on BW, I believe only one knows what I really do (DID) while the Sun is shining.

Back in 19-dickety-aught, I was an engineer and owner of a prototype engineering firm.

One of our specialties (multiple patents area) was in the suspension of our equipment -specifically said king pins, links, and trunnions!

and... NO, Pounchy -NO FAILURES, catastrophic or otherwise! 😂

Jaff Trunnion - a Dickension character and Engineer/Owner of an Industrial Revolution foundry & machine works, manufacturing linkages, swivels and pivoting mechanisms (pat. pending) for all manner of steam driven machinery and mechanical contrivances.

Sounds about right!😂

Welcome aboard!

I just traded my last A8L this past month! 😠

I keep trying to send photos, but have been unsuccessful doing this for BeoWorld.  But since this thread keeps coming back, I can't resist posting.  

In the past couple of years I've been hard at work on a book about high-performance driving and auto safety, and this has enabled me to build up a nice little collection of cars (for research, of course, of course).  So, without photos:

A 2006 Honda Element (for lugging around BeoLab 5s, of course – I can fit 5 of them in nicely, plus a dolly).  

A 2002 Audi S6 Avant Quattro with some reworking, a little rortier exhaust system (useful for going to the Symphony in Boston when its snowing – or even when it's not)

A 1995 Mitsubishi 3000GT VR4 Spyder (Mitsu's twin-turbo AWD 4WS lil' monster with a retractable steel roof – they only made 800, for fun!)

A 2005 Morgan Aero 8 (the new aluminum Mog with a 4.4 BMW V-8 and gorgeous-sounding side pipes – pure essence of car!)

A 2011 Mercedes C63 AMG with the development package, for track days (to study hooliganism in the field).  

And I just test drove a new Morgan 3 Wheeler, so if I can just lose 30 lbs  .  .  .   

Thanks for listening!

Aero and Avant for me!

What a diverse lineup! A little bit of everything! Well done. 🤒
