rc18b diff tightening

[evst 360]

I recently (a few months ago) built a factory team rc18b kit. The car is great, but it has one problem. The diffs seem to be tightening themselves. I will loosen the screw by about 1/2 turn, and then they are tight again after a few runs. Has anyone else had this problem? Any help is appreciated. :cool:

hmmm..... maybe your diffs are getting crunchy, meaning need rebuilt. after 2 months those diffs should, try that and see if that helps.
