Durga help, Thanks

[sam mansell]

Hi everyone I am new to this forum and have recently purchased a Tamiya durga that has a Novak 7.5 GTB and run all orion 3200 lipos. I have also purchased a few upgrades: TRF 501x damper set, DB-01 slipper clutch, front and rear aluminum suspension mounts, and CVD's. Any way i have recently run into a problem with it, after every run the front diff loosens up really bad and sometimes doesn;t even last the whole race. The car is new to me and if someone could please help me out that would be great.
Thanks
