Came across another thing to get AW/JL Tjets to run smoother:
The front axles are practically a brad nail (you all know this), but closely examine the surface near the nail head. It should like like this:

But I've noticed several of my cars' axles look like this:

you can imagine the hopping that little bulge is causing when a car is running, you can feel it when you hand-spin the axle.
But you can grind down that bulge with a nice grinding stone (like one of the Dremel attachments) and make it smooth like the first figure above.
After grinding off the bulge, the cars all ran much smoother, a couple cars that hopped horribly while running at a decent speed are now very smooth, much to my delight.
Sorry, but the editor won't let me center the 'nail heads' properly, but the 'axles' are placed right.
