Did I try the AE spring and nut combo? Yes. Did it still loosen? Yes. Was the diff loosening to a point where its noticeable? A little. Did I wanna keep trying to make something work? Why bother?
I had the same problems with my plastic AE diffs and my SD diffs. I've asked numerous times for SOME explanation of why HPI decided to go with the design; with NO answer...
Care to explain why that design was chosen?
My best recommendation is to keep the diff as tight as possible without locking it up completely. The downside is that you'll have to keep tightening after every run.
I must be one of the lucky ones since the only thing that I did was use the AE diff spring when I assembled it and the diff has stayed nice and tight yet smooth and I have raced the car approximately 5 or 6 race days.
I did, however, use the Accer ceramic diff balls, but I do not think that would be why the diff is staying tight.
Just food for thought.
