Loose shock? or loose headset?

My 90's model Marin mountain bike is converted to a threadless headset by the previous owner. A new to the bike but used front shock is installed. Something jiggles over small/little bumps, but not big bumps. The front end assembly functions correctly over everything except small/little bumps in the road.

Is there a test to determine which is causing my problem, the headset or the shock?

Loose headset detectable several ways, but simplest is to stand over the bike preferably on pavement, lock the front brake (pull caliper maximally) and push-pull the bike
forward and backward a bit. A loose headset will be obvious with a clear movement of the fork in the head tube. Rattle is (probably) coming from the shock some where,
but push pull everything in the front: brakes, shifters, wheel rim to check for loose QR clamping etc. Some times the apparent source of a noise is not the real source.

It's in the shock then. I hoped it is coming from the headset because that would be so much easier than disassembling the shock to find the problem inside. I've never disassembled a shock to rebuild it before.

What kind of fork is it?
The really cheap ones are "never" right, not even from factory.
Mid- and high range units tend to be rebuildable as long parts are available. There are bushings that keeps the telescoping action aligned that sees some wear.

That't the big if, just about all the mid-high end fork manufactures from the 90's no longer exist in the form they did back then (buy outs like Rock Shox & Manitou) or gone out of business (like Marzocchi with Fox buying the remnants) and unless you are willing to hunt spares for most fork spares from then are very hard to find/non-existent other than dust seals.

It's a Manitou Axel 80mm. An 03 or 04 model. It's not original to the bike.
