After my meltdown of my Max4, I have been doing the major maintenance my Raminator with some upgrades. I have been having a hell of a time with the rear diff. After the rebuild, it spins well when you grab both sides and twist. Spinning the gear side diff output shaft allows it to move with a little resistance. When you just try to spin the diff housing side of the output shaft it binds badly.
I have been following the HPI Baja diff videos from Fast Eddy to try to find help, since it is pretty much the same diff.
I did construct the diffs with the flat side of the (new) inner differential washers facing towards the center of the diff on all six sides (rounded sides facing the exterior). I also replaced the differential housing and upgraded the differential output cups to the supposedly stronger V3 version. Using 20k diff weight by team associated, I filled the diff to level with the top bar of the differential spider gear and I let it rest for 30 minutes to ensure I filled it with what I thought was the right amount. Gears look mint. I also gradually tightened the diff case in a star pattern to avoid any warping.
Any ideas? Yes I know this sounds like a rookie mistake and it probably is. My experience rebuilding diffs is with Arrma.
I appreciate all the help.
