Front hub bearings

[NIsaacs]

I only have 75K miles on my 07, so it’s getting time to worry.

326k on my '01 oem's, so sleep well RV

That ain’t grease making it shake, it’s flat spots on the tires.

Naa,,,, its the grease I've had 3 separate set of tires on the truck, TransForce, Toyo CTS, and Now Michelins LTX Defender. they all do it, the Toyo CTs were replaced with the Defender do to vibrations..

 

[CoastyAV8R]

Just grease them, Some does leak out past the seal just wash it off, I have sooooo much grease in My hubs in the winter on ice packed roads the steering wheel shakes until it warms up ( About 2 miles) or on clear pavement, Some grease at 75/100K miles and have reported 300K plus on OEM bearings.

So that's the ABS sensor hole eh? How often do you grease the bearings via the ABS Sensor hole?

 

[TCDiesel]

O about 50-75K Miles after the first when New. Yep that's the ABS Hole, it will take about 30 Pumps per side and I will mention this again it will burp out some ( after driving) just wash it off at the self serve car wash ,I did mine back in 2013 and we had some pack ice roads this year already and sure enough it still good BC it shake's a little when cold and icee road. The 2013 currently has 38K miles. My old 2003 has 260K miles on the replacements.

O I see what you mean, BC its been sitting and Yep that will happen.

Yep, it's really bad when it's -40 or colder.........load range c's will thump along for 10-15 minutes before they build enough heat internally to become round again.

Reminds me of some old bias ply 38" super swampers I had on a Toyota...that truck didn't get run over the winter months but I remember hopping in it in 20ish degree weather and wondering if my fillings were gonna come loose before the tires smoothed out

 

[cricha]

any particular type of grease to use when putting grease in through the sensor hole? I've always used a moly hi-temp grease on wheel bearings. is this compatible with whatever the factory uses?

 

[Ozymandias]

Yeah sure, there isn't much grease in it from factory, just a tiny amount.
I used regular wheel bearing grease for brake disc hubs.

 

[gsbrockman]

When I replaced the bearings in my 2014, the curious in me prompted me to remove the ABS sensors and look at the amount of grease in the new SKF bearings. They were what I considered more than adequately full, and the grease inside them was of a blue color. The grease would remind one of the grease supplied in a CV boot kit used on front wheel drive cars.

 

[JR]

The problem is, among others, CV joint grease is typically a No.1 NLGI grade and not suitable for wheel bearing use....unless your on the north slope.

FWIW, wheel bearing grease comes in multiple colors and does not indicate performance. Initial color is nothing more than helping the user identify a correct or incorrect grease.

I never once indicated that anyone should go out and purchase a quantity of CV boot grease and install in these style wheel bearings that are used on RAM HD pickups.

I was only trying to [be helpful] let the membership know the color of the grease that was in my new SKF bearings in color comparison to the grease in CV joint boot kits.

 

[Ozymandias]

Good to hear that SKF still build quality replacement parts.

My brother’s 03 2500 Hemi went out in 100K, he now owns my 04.5 (see sig) it now has 140K with OEM uni bearings. I guess it’s a hit and miss kind of issue.

Not only this, also the bearing and the way it is made surely evolved over the last decade.
When the Gen3 started it was a new design for a HD Truck, nowadays its the standard design and they learned over the years going by.
Same as the CR Design, then new and a lot of problems, today it works flawless.
Today we see the issues with the DEF System, and they will be gone in a couple years.

Stop it....stop it, I say....with all of this common sense.

had a hub bearing fail @ 21k miles sounded like a brake lath during a hard right turn into work road 1 day, daily off road driving on rocky railroad right of way had vibration and fresh tires alignment new truck rough roads caused failure, dealer replaced both under warranty, had a rattle could not find it was the bearing going away

Must be nice! definitely is not covered under the 5 Yr powerptrain warranty! $800 for two new hubs after spending $2K to come home from overseas (Military) to spend time with father in law after quintuple bypass surgery.

But I still won’t give up my RAM!

 

[Cummins12V98]

I think I would pursue wheel bearings being covered by power train warranty. I do have 100k max care so one way or another I’m covered thru 100k.

 

[JTMATTEL05]

I thought they would be too. Chevrolet covers there’s so I figured so would Dodge/Ram. And I went to the website that explains the warranty and it specifically states it does NOT cover the hubs. I was not a happy camper
