Greasing front wheel bearings

[B.G. Smith]

I have done that but I used 75W90 gear lube.

Interesting...

I cant see how gear oil would play well with the existing grease or seals ....

The " Unit" is sealed , the bearings inside are not so any grease put in through the ABS hole does get into the bearings. Overtime some grease works its way past the seals if there is alot in the unit.

I was leery of this procedure but now realize it works. Had I known I'd never gone with Dynatrac's.

Somewhere long ago I posted a couple photos of an adapter I made from a small piece of aluminum. One hole for the bolt, a Zerk threaded on the other hole, and a small O'Ring. Can't find the adapter any more, I think the neighbor got it.

Ram Man sells an adapter. Good 'ol boy. Sounds like he lives under a flight path.

While I appreciate ingenuity, I think most people can do this with stuff laying around the shop. Thanks for everyone giving tips to save money.

I just use a rubber tipped grease nozzle , available at any auto parts store. https://www.oreillyauto.com/detail/...2130/5727368?q=rubber+tip+grease+nozzle&pos=1

i wonder why one couldn't use gear oil, like is used on the rear axle bearings... if it's a sealed unit...

If the seals keep it in, yes, I think too why not. Oil is the best for the bearings by far.

I've done the same across 4 trucks and never lost a bearing - one has 750k on it

Interesting. My truck is an '02 with the OEM front bearings still in place at 345,000 miles - never been greased. I have been thinking about replacing them, but maybe I should just grease them. Has anyone had any issues with the ABS light coming on after adding grease?

i'd imagine one would have to vent the unit. so thats why grease is used over oil. but i'm not really sure.

Never heard of an ABS issues from greasing the hubs and I know many people who do it.

Just completed the front hub bearing pack, Quick, Fun and Easy. I used a standard grease fitting, flat washer and o-ring. And a hand operated cartridge type Grease gun.

I started to do this on my 03 today, but came up with a few questions...

Does the ABS sensor work off of magnetic impulses?

Do I need to clean off the tone ring so it's visible?

Is the such a thing as putting in too much grease?

 

[crispyboy]

Something I have to add to my list. Question: Any old wear bearing grease or? Thx for the post..

I have been using Valvoline synpower grease. I would use an EP grease with moly for wheel bearings.

I would think so, non serviceable units generally have a type of elastomeric seal and are not designed to be able to vent.

 

[Ozymandias]

Grease doesn't interferewith the ABS, nothing to watch out for on this side.

Amount, yes don't fill it all the way up.
Give it 10 pushes with the grease gun and call it a day.
