I have read on here about guys greasing the front hubs on their trucks by removing the ABS sensor and pumping grease into the sensor hole. How do I do this? How do I identify the ABS sensor is it as simple as it's the other line going to the caliper that is not the brake line? How do I remove the sensor to access the hole? It looks like a rubber boot going into the caliper to me...so do I just pull it out? How much and what kind of grease would I use?

Thanks....67k on the truck and just trying to prolong the front end!

I searched and I can only find people talking about it, but not explaining how to do it which causes me to believe that it is simple but I don't want to mess anything up.

 

Well I have never done it, but you need to remove the caliper and rotor, then you will see the abs sensor on top of the hub.

 

The ABS sensor will be the only thing with a wire going to it on your hub.

 

Thanks for the responses guys....anything from anyone who's done this?

 

i don't know if they are the same as mine, but 247000 miles without any extra lube is good for me

 

I done this about 6 months ago after replacing the brakes and rotors. Just like stated above, remove the abs sensor going into the hub assemble. Still in my original hubs after 150,000 miles.

 

I do not see how shoving grease on the outside edge of a sealed bearing is going to do anything. Please school me.

 

By removing the abs sensor you can put grease inside the hub.

 

Speedy,
How exactly do I remove the sensor? Is it a rubber boot? Do I just pull it off? How much grease is correct? I've never lubed anything like this, just zerk fittings and bearings during install.

 

You need an allen wrench to remove it. No boot, it just pulls out. You will probably need a needle like you use to grease the front drive shaft to get the grease inside the bearing housing.

 

Great, more front end maintenance for me to do. Guess I will add this to the list.

Actually I am glad to read this. I wondered about how long that expensive part would last without a grease fitting.

Question - After placing grease in there, does it interfere with the ABS Sensor? How does the sensor pick up movement of the wheel?

 

Here's a pic on my 04.5 2wd.

 

I did mine. No problem with the ABS sensor. I use a grease gun adapter with a rubber cone shaped tip. The area between the inner and outer bearing is not sealed so grease will flow to the bearings. I only added a few pumps of grease reasoning that when ever I'm working on the brakes etc. I'll give it a shot or two, and not blow the seals because over the miles, excess grease will leak out past the seals. A little grease is better than no grease or too much grease.

 

Thanks totallyrad.....you are rad!!! That's exactly what I was looking for. It should be the same on a 4WD, correct?

 

When I blew out my wheel hubs I noticed that these bearing assemblys are not built all that well. I have not yet greased the bearings I have, but I have no doubt that from my observations of the blown bearings that adding extra greese everyonce in a while will not hurt. As for these things being a fully sealed unit, they are from the outside in but will transfer from inner to outer.
