What happened to torsion bar suspension?
The Minor remained in production largely unchanged until 1972 and was replaced by the Morris Marina which also used the torsion bar-lever arm damper system for its front suspension—one of the last new cars worldwide to be introduced with the system and which remained in production until 1984.
Do torsion bars sag?
Torsion bars definitely can weaken. Typically it is the passenger side that does it more often and that is likely due to the heat from the exhaust/catalytic converter. About the only way to tell is if your adjusting bolts are almost all the way in.
Are torsion bar keys bad?
The keys just drop down the location of the torsion bars. They also have an adjuster bolt to raise & lower them. Most mechanics don’t recommend cranking on the torsion bars, as it’s hard on the alignment.
What causes a torsion bar to break?
There are too many reasons why a torsion spring gives up to answer this, but long use and over use are typical reasons. Others are poor heat treatment and or draw back, a flaw in the metal, or a bad alloy mix.
Why dont cars use torsion bars?
The major con of torsion bars is they don’t work as well as other systems. This is due to their simplicity: If a suspension system isn’t complex enough, it can’t handle bumps as well. The other con is that cars with torsion bars don’t handle as well.
Will cranking torsion bars hurt?
Craning up the torsion bars to get the truck back to stock ride hight does not hurt anything or wear out cv joints prematurely. Cranking up the torsion bars to above stock ride hight can wear out cv joints prematurely.
Do you need an alignment after cranking torsion bars?
Yeah, the cranking will require an alignment. If the bumper shows significant sag then it may be contributing too to an alignment. It’s not an immediate need but something you should not let go too long without addressing. Give the truck time to settle with the addition of the bumper and the new crank.
