LJDB 103 Posted November 4, 2017 Hey guys went to change my gear set back to the original 2.92 and can't get any load on the pinion bearings. The car is a 1977 te cortina with a 0578 housing. In this housing Iv had 2.92, 3.23, 3.45 and 3.7 in it at some stage or another through different engine combinations. The original gear set is the 2.92 the same set I'm trying to refit and doesn't have a collapsible spacer like the later diffs, it has a shim. I removed the bearings from it along time ago and suspect there should be a another shim under the main pinion bearing. Can anyone confirm this. All the other gears I have changed used have been from e series cars and use a collapsible spacer. Share this post Link to post Share on other sites
