I have 2 Walthers Proto SD60's, love them, then for Christmas, I received 2 Mainline SD60's, they look great minus a few details, but the body of the locomotive is very wobbly compared to the  trucks. When it starts to move, it rocks back and forth, LOTS. Is there a way to tighten up the trucks?

Wondering if anyone else has noticed this and if there's a way to fix it?

Truck gearbox clips vs frame

Dear?? (SD90), Suggest taking the shell off, and checking the tolerance/distance between the bottom edge of the truck gearbox tower clips (the things which keep the trucks in place when the loco is lifted from the track) and the top edge of the frame that the clips bear against. I have noted some P2k/Walthers diesels modified with styrene shims between these pieces so that there was less slop distance, and thus less room to rock... (shades of "3-point suspension" a la tuning a freight car?) I'd also check the driveline for any binding or rhythmic clicking. Even a mech with "sloppy" truck<>frame mounting should stay reasonably stable unless some out of balance torque force is moving it about... Happy modelling, Aim to Improve, Prof Klyzlr
