The torsion bar is made from cryogenically tempered spring steel, and is highly stressed due to the 90 degree twist that it has to go through every time the door is opened or closed. Any scratches or corrosion pits (even microscopic pits) can lead to fatigue cracks in the bar, which will eventually result in failure of the bar in fatigue. The bar should be thoroughly cleaned with a fine scotchbrite pad or stainless steel wool, but not regular steel wool. The iron particles in steel wool will create a corrosion cell very quickly, if they are imbedde din the material of the bar. The cleaned bar should then be painted with a good rust-inhibiting paint, or treated with a rust inhibitor such as cosmoline, or something like it. BTW - replacement of the bar is no big deal ... BUYING the replacement can be, as I understand it. --- In dmcnews@xxxx, RJRavalli@xxxx wrote: > How worried should I be about slight signs of torsion bar rust on my driver's side that I have been recently noticing?
