The Mad Modder
I totally agree with u
Dont know, never hear of these clips?
its very common to wearout the drive cups like in that pic, honestly that is mild.
I sure some of the other guys will chim in.
Its all about run time, for each wheel rotation there is two spots where the dog bone pins slides accros the cup (Vertical position TDC & BDC)
over time this wears out the dogbone pins as well as the cups, then as it gets worse, it starts to hammer back in forth inside the drive cup.
And trust me if u hammer and rub something it wears down real fast. all it takes is about 100h or run time, maby even less for off road cars. u can put grease on there, but if dust and dirt get in the grease, it turns it into a cutting compound and have the oppsit affect.
I hear people saying well mine has not done that, I say u havent been driving it long enough
