Ok, so I don't really do diffs or gears. I'm not afraid to go into them, but the need to rebuild or replace gears in the dealership has not been high in the last 10 years, and I do mostly drivability stuff.
But the Explorer's rear needs a rebuild. The pinion bearings are loud (no play yet) and I suspect I have a suspect carrier bearing in the diff.
By chance I happen to have a gear set for it, I just need bearings and an install set. My concern is that I have heard horror stories from other otherwise competent mechanics, who can rebuild diffs, that pertain directly to repeated failures at rebuilding the IRS version.
Are they really that bad to do, or is there something that makes it drastically different than doing a solid 8.8?
