I don't think mine even have lockwashers. If i do they are totally flat.One more safety comment... Lock washers are not sufficient for the bolts holding the half shaft flange to the stub axle flange... Get some saftey wire or french locks.
I used 2 sets of poly cusions, one on top w/ a washer and locknut and one on the bottom, they sandwich the spring. Ride height is adjusted by moving the 2 cusions up or down. You can compare the spring on the bolt w/ the springs in the valve train, at a certain rpm those will float. The same will happen with the leaf spring, ride on a very rough road with a high susp. frequency and it will start to exhibit that type of behaviour. Of course, this is more an issue with softer springs and the road would have to be pretty rough.
As for the lockwashers, they will work if you use loctite. That's what I do sometimes, those french locks are a pita and impossible to get here. Wirelocking all those bolts? YAAAWN!! that's no fun at all.
Ok, I've had a set properly torqued with new lock washers loosen in less than a thousand miles. How can this be? How about a failing Ujoint.I don't think mine even have lockwashers. If i do they are totally flat.
But what do i know. I only have 400,000+ miles of driving experience with my car.
I get the resonance frequency of a spring thing...
Are we really operating in a range that would come close to even a harmonic? (I dont loose any sleep over this one :laughing: )
Second, dont leaf style Semi-eliptical springs have a natural damping term with the friction of the springs on themselves? (as apposed to mono leafs) and since each leaf is a differnt length you would think some of the terms would cancel or at least keep things from resonating.
The double and triple valvespring thing... Beehive Springs? (exept the swallowing a valve thing...)
are you going to be one of these worry warts? I'd be worried about all those custom panhard bars and end links coming apart.Ok, I've had a set properly torqued with new lock washers loosen in less than a thousand miles. How can this be? How about a failing Ujoint.
No Lockwashers & Locktite is ok but I prefer a visually verifiable locking mechanisim.
(400,000) Some times it's better to be lucky than good.
