RE: [Chrysler300] Burt’s Comments/ 57 Torsion bars

["'Terry & Andree Hoeman' tehoema@xxxxxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Interesting experience from long ago.

I grew up a ford guy since parents always used them-and remember my first experience with a MoPar.  I was in front yard and late 50's Plymouth came down the street and stopped in front of house due to broken torsion bar from bump a block away.  Car was near dragging bumper on street and had to be towed away.  Not a good introduction to MoPars!!

If I hadn't married a gal whose father was MoPar parts man would probably still be doing fords.. Scary!

Subject: [Chrysler300] Burt’s Comments/ 57 Torsion bars 

One of the things Burt spoke of at Keith’s home, was the suddenly discovered stress corrosion of 57 torsion bars at the end sockets . I know of this first hand , as going around a rotary ( Massachusetts bad idea) at very high speed as a passenger “ up on two wheels type thing “ in 1960 , in a 57 plymouth the highly loaded  one snapped , putting 4 of us into guardrail . Totalled the car . Had same  thing  happen to me in a 51 ford at same place , ( steering box tabs broke off box at frame  bolts in those ) — maybe it was just me at 17. Or debugging designs! 
Burt described packing them with heavy grease when they found this out (  a line of corrosion encircles the bar at the mouth of the hex socket , due to salt rust etc . ) That raises stress , like a notch leading to failure . Being a spring in essence , the steel skin  is highly stressed there. 
I loved how he calmly described this . Failure in engineering in new designs happens , somewhat normal , life testing  3x expected use is the only way to find obscure things — but spraying it with salt probably not part of it , that year. Bet it is now. We forget that “ torsion aire “ ride was a major suspension and engineering innovation , a part of the 57 cars .. lots of new parts never used before . 
I am working on a 57 dodge , and I know later years ?58 59 May have rubber boots for this , 60 does . Is it at both ends of bar ? When did boots start ? Do they fit 57 ? Because I never saw a failed one , seeking info on this . Bad surprise awaits if not addressed , and the older the car more likely to happen . Pack with heavy grease at least . Bar interchange ?? 
When it snaps wheel goes way up into fender hits upper stop , iF in a curve at high speed can lose control .
Good thing to bang around , prompted by  the meeting with Burt .  
Thank you Burt !
