Headtube or headset sticking ?

G'day,

When I push forward on my bars with the front brake on hard the
steerer/headset/head tube sticks. When I pull back it releases then sticks
on the frame side.

How can that be fixed ?

It's done it for a while but I'm not sure which part to lube. The headset is
a needle bearing sealed cartridge and there are 3 stem spacers at the top.
I've tried tightening and loosening the stem retaining bolts but it seems
lower down near the bottom part of the headset.

Help me with my sticky clicking bits please !

Oh yeah, it's a threadless stem going into a set of Marzocchi Z.2's

I've got the same problem with a ringle headset and a psylo.

To tighten a loose headset, you need to loosen the stem bolts on the side
of the stem. Then tighten the bolt that goes through the top. Then do
the stem bolts up again.

If you've had this problem for the last two years, then there's a
possibility that you've flared your headtube.

It's the top part of the aheadset that's slipping, the cup that attaches to
the headtube. It's moving about 1/2 a mm or so. Can that be tightened if the
headtube is still square ?

I haven't ridden my MTB for ages since I got the road bike hence the reason
for the same question 2 years apart.

Ack !, I should add I've tightened the bolt that goes into the star nut so
much the seal on the headset is bent out of shape. Headset still moves under
stress.

The steerer has about 1-2 mm clearance at the top and the top cap isn't
rubbing on it as far as I can tell.

The headset is all one unit. You tighten the whole thing rather than just
the top or bottom sections. There should be no back and forth movement in
the headset at all, and should be easy to tighten.
