adam-__- Posted September 15, 2008 Report Posted September 15, 2008 (edited) Hey guys, I've just purchased a welded diff centre for my car and I think I've run into some problems before I've even started. My car's currently running a standard open borgwarner diff with 3.9 ratio and the welded center I just bought is the 4.1 ratio'd one from the automatics. What I'm confused on is whether or not I can use the 4.1's center with crown wheel in my manual housing which still has the 3.9 pinion? In other words, can I put a diff centre which has the 4.1 crown wheel into a housing which still has the 3.9 pinion gear in it? Or will I have to change the pinion gear to the 4.1 ratio one for this new locked center to work? Cheers, Adam Edited September 15, 2008 by adam-__- Quote
Redwarf Posted September 15, 2008 Report Posted September 15, 2008 No. Use only matched crown wheel and pinions. Can't mix and match. Quote

philbey Posted September 16, 2008 Report Posted September 16, 2008 Haha. Try it. Will be funny. Hypoid gear sets are all matched correctly, you definitely cannot mix and match like Dwarf said. Quote
