USA 4X4

This was the diff oil from that low K JK, both were the same. It might be 5 years old but at 20Km there still really brand new, they need to run/bedded in. Diff gears are usually "lapped" as in run on a machine to help bed them in a little prior to installing. This is why a crown wheel and pinion must NOT be miss matched, they are a matched set and at the same time all the new metal faces will still take a little more bedding in, so change the oil on new diffs soon after install or just run more metal thru them and wear them out prematurely. It’s something no one really considers in a cars... engines, gear boxes, even new brakes and clutch need bedding in. There are procedures to this out there in the web, check them out one day, look after your pride and joy. Do an early service on a new machine or engine/diff rebuild, bed your new brakes in, run your new diffs in. Show some mechanical sympathy. It will benefit your wallet the long term I promise you.
