Re: Eaton Posi rebuild
I've been meaning to pull the cover and look for other issues like broken spider gear teeth or something.
I haven't been able to observe personally from outside the car but bystanders who noticed the popping when it was first built said it appear the axle was twisting then popping to unload like what happens with a car with a spool? It occurs in situations where the car is only slightly trying to turn, such as real wide curves on the highway.
The car is used for both and the original Eaton served me very well for nearly 10 years with no complaints. And yes, after a couple years I stopped using the additive in it.
I have 1 bottle of GM additive and I think the 2nd bottle was the Ford equivalent. Seems to work when the fluid is fresh and again got better when I very first added the 2nd bottle of additive.
