How much should it cost to tighten front stabilizer links?
If loose this means they’re worn out unless someone has had them apart and failed to tighten them. There is no tighten to them.
I don’t think they can be tightened. They are not adjustable. They are links; solid, physical links. They connect one part to another. There is no adjustment that I’m aware of.
I just bought a pair of them for a total of $16.35
