Did it have telltale wear marks before you had them chromed? If they were very old then the wear you see now would have been completely through the chrome. If you haven't changed anything else you might have tightened them a bit out of true. If the stanchions slid straight into the triple clamps without you having to tweak the top clamp to get them in they are most likely straight, the way to check is with two straight edges (steel rulers) as far apart as possible on them (as they sit in the triple clamps), one near the top and one down the bottom, an eye check across the two edges will easily show up the slightest discrepancy.
Any time I assemble a front end (even a wheel out) I fit everything - callipers, axle bolt, pinch bolts - just nipped lightly up, then take the bike off the stand and bounce the front end hard a few times against the front brake, to let everything sit where it wants to, then tighten it fully. I would try this before I start stripping it down. If you do decide to strip it, check if the sliders are very free to slide up and down the stanchions with everything attached to them (wheel, guard etc all tight in place) without the springs in place and the oil drained.
A slight weave sounds more like over tightened headstem bearings, or worn ones, but could of course be many things.
