I’m running a HPI 16 tooth hardened clutch bell with a 49T plastic spur on my X4.6. No matter what I do I cannot get the gears to mesh flush with each other. The truck runs great and can do a standing back flip once it’s warmed up! I never really noticed this before and yesterday I did a complete full tear down of the front and rear ends, changed all the fluids in my shocks and diffs, did a full tear down of the engine and transmission, cleaned and soaked every bearing and after I re-assemble I noticed this in the picture.
