Default Quartering LGB Mogul

I have a D&RGW Mogul 21181. It wasn't getting connectivity to the track through the engine, only the tender. So I took it apart and fixed that problem. I have taken it apart several times before to install a DCC decoder and replace the smoke unit with no issues. This time, it is making a lurching motion and driving slow. So I took it back apart to make sure the side rods weren't binding. Now it is worse. I think maybe they aren't quartered correctly. I am also ordering idler gears and new grease with my next order just in case. What is the best way to ensure the wheels are quartered?

OnlyTrains.com has a FAQ about this. From their home page, select LGB Questions, then on the next page select Repairs. Near the bottom of the list is the question "Why does my train lurch down the track"; expanding that FAQ will give you the quartering procedure.

Quartering is 2 things to check. One is that the wheels on an axle have a 90 degree offset. Does not happen very often but can occur if a wheel/s is changed.
Now the gear driven axle/wheel on one side has to be in the same position. I align the screw for the side rod to be in the same position on both. On the LGB mogul the middle axle 'floats' and is only driven by side rods.
