I went through 2 DC boxes then got the lifetime guaranteed one from napa. 50k and no problems with napa, plus steering effort is reduced. I use AMSOIL fluid in the napa box and last week finally put on a DSS just to keep everything tight.

 

They had some design problems and stopped selling them....maybe 5 months ago. I would call them. Don't know present status of their product?

Well if that isn't comforting..
