I've been noticing more noise lately from the springs that are in the part of the top (above door windows) that meet the corners of the windshield. The noise happens when the body flexes. The springs creak.

Can this be quieted down with adjustment/grease?

Are there mods to reduce body flex in cabs?

A dab of oil on the ends of those springs will silence the twanging noise you sometimes make.

Try a front strut tower brace - I have one installed in my cab - works great.

 

Someone told me that Cabs shouldn't have adjustable shocks as they are too stiff for the body design. Of course, I was told this after I spent a fortune on new suspension pieces of the adjustable nature. Is this correct?
