Exactly You need to remove the door, clean and lightly lubricate the
wheel bearings.

Bearings? You are making the assumption his sliding door even has
bearings.

I suspect many doors, out there, are as cheap as mine. No bearings
and the wheel adj blocks are shot (stripped threads in the cheapo alum
adj blocks). You may be better off replacing sed sliding door with a
better one, though it's gonna cost you! I hadda take a 4-1/2"
right-angle grinder and open up the frame to allow the near-broken
wheel adj blocks to allow the wheels to even engage the floor rails.

I'll be replacing it, eventually. Sad! 8|

BTDT. Original builder quality aluminum frame was replaced after 12
years. The Pella was replaced after another 22 years. Now I have a
Marvin that should outlast me.

As others stated, the fix is to repair or replace the wheels. I did
that once on the Pella but a few years later the door rotted internally
where it held the wheel assembly. Best fix is to replace it with
something other than a slider, but this 8' in my family room looks out
to the woods and I don't want to give up the view.
