Putting in lockers and 4.11's and don't want to break 'em.

Don't use phosphor bronze. Phosphor bronze is attacked by the extreme pressure additives in diff oil.up2nogood wrote:Yes pls, was nearly going to give up on this...
Where's you get the phosphor bronze from?
Leaded bronze is an alternative that is good for bearings. The strongest of the readily available bronzes is aluminium bronze (has superior mechanical properties to phosphor bronze). The reason aluminium bronze is not used as often as some of the other bronzes, is that it requires good lubrication - something that should not be a problem in a diff.

most of the good GL5 gear lubes should be yellow metal safe so it shouldn't be a problem. My understanding is that few blenders use un-reacted sulphur (olefin sulphide) these days, which is what reacts with bronze/brass/copper.Bush65 wrote:Don't use phosphor bronze.

this is from a blender on another forum
The Sulfur and phosphorus EP compounds in the older formulas would stain and corrode copper alloys of brass and or bronze.
Today's modern EP additive packs contain chemicals called "metal deactivators" and corrosion inhibitors which keep the copper alloy metals from corroding; I.E, they "buffer" the EP package and prevent copper alloy metals from corrosion while allowing the EP package to protect the gear teeth and bearings.
