Greetings:
While doing a little R&R on my torsion bars, I found the right one had a couple of interesting “nicks” on it after I had scraped off all the (mostly) surface rust – The “nicks” are about 20” from the hex end and too far away to have been caused by the lateral support bar – Plus, examining the lateral support bar did not show any indication of contact/wear - They are also VERY shallow and can hardly be felt when “scratching” at them with a finger nail – If it had not been for a small amount of paint at the bottom of the “nicks”, I would probably have missed them all together.
Other than the “nicks”, the torsion bar was in fairly good condition and pretty straight when rolled on two edge blocks.

I have some questions that hopefully can be answered….
* Anyone know how our torsion bars were made – Forged or drawn with forged hex ends?
* Is it possible that the “nicks” are some sort of artifact left over from the manufacturing process?
* Any cause for concern? – Is it replacement time?
The left torsion bar was in much better condition with most of the original paint still intact and only some slight surface rust on about 1/3 the bar – Though a close look at the area near the lateral support intersection did show some ever so slight “rubbing” that did little more than take the paint off – A close look at the left lateral support bar seemed to suggest it was caused by a build up of dirt on the top of the bar - As once the dirt was brushed away, there were no signs of any direct contact – The left torsion bar did have a very slight “wobble” though when rolled on the edge blocks.
Thanks in advance for any thoughts you may have on this subject.
