I was reading on ram1500diesel forum that you can grease your front bearings by removing the abs sensor. Since I'm installing an ome lift on the crd, I said it's a great opportunity to check if this can be applied to the crd. It turns out that removing the abs sensor from the hub exposes the portion from in between the ball bearing rings in the bearing, allowing to grease the bearing. I do have relatively new skf hubs, but I still applied some generous amount of grease. This is recommended especially for folks that have good bearings that are not new. The main reason bearings fail is due to lack of grease or because water gets inside creating rust.
So just gently remove the abs sensor from the hub, prying it out bit by bit, apply few pumps of grease, spin the bearing few times and repeat till it is full of geease.
In the below pic you'll see some white Grease that's present still on my relatively new hub assembly.
Just be cautios, if you use a needle nose Grease chuck pull it out when turning the bearing as it will bite a bit on the abs metal ring that's inside of the bearing.
Then clean the abs sensor oring and insert it back gently by twisting it left-right. Once done, chances are that the bearing will outlast the jeep.
