That said, there's a bush in the eyelet that bolts to the
lower arm that the arb attaches to.
If it's never been replaced, it may tighten things up.
Poly replacements are available.
There are a couple of mount rubbers where the central part of the arb meets the front subframe that could feasibly be upgraded too.
From my own experience, if the eyelets have never been replaced, they're likely to shear off while you're trying to unbolt them..
