Anyone else experience this issue I'm having? Something seems off for this to be my second wheel bearing failure in 10 yrs. Geez

Are you trying to show the grease on the CV shaft? Yeah, I went through a couple hub bearings. They weren't Timkens though. They were cheaper brands that were given to me as spares. You also need to make sure you keep up on the torque on the axle nuts.

 

[BLOWN9646]

Yes, showing the grease on the axle. It was a Ford bearing used but think I may have found the issue. My irs isn't center correctly (a previous owner did irs bushing upgrades), and i was using incorrect wheel spacers on the side that sticks out further, and believe the wheel wasn't seated on the hub!

Anyone got a part number handy or brand recommendations?

The wheel shouldn't affect the hub bearing. The only thing affecting the hub bearing is the nut not being torqued properly and coming loose.

I'd suggest Timken. I believe the cone style is the correct style. Not the ball bearing style.

Ok. I had to put the wheels back on to make a visit to the doc. I'll report back later when I get home regarding if the axle nut came loose or not.

Tight as it was years ago when I put it back together with a new oem axle nut. 250lbs/ft

Poor rear alignment could cause premature bearing failure too. What do the tires look like?

 

[BLOWN9646]

Tires are done, was ready to be swapped. Rear alignment is off, car drives straight

You got your monies worth out of those tires. Only time mine look like that is when I burn them down during a burnout. Not from mileage.

 

[BLOWN9646]

Yeah def got my monies worth on these nitto r'$. Got one more set in the basement from eBay purchase a few years ago. Can't find em for that price I paid anymore these days, think it was around $450/pair

I don't know. I think your alignment guy is pretty good given how smooth your tires are. He might want to look into bodywork.

I wonder if your bearing is like mine when it tried to kill me. After almost putting my car into a wall I pulled the wheels and inspected everything, but everything seemed good and tight. Finally one day I spun the axle nut off and the bearing fell out in pieces. Somehow the nut was keeping everything in place and made it seem good when moving it by hand.

I would get the alignment checked when you get hew skins, looks to me like the rear could be toed in a little, insides are worn more than the outside, it would still feel like it drives ok but it can wear tires and possibly overload the wheel bearings. Worth the money even just to eliminate the alignment as a cause

Yep. Same thing happened to my IRS on the passenger side. I thought I had a torn boot until I pulled that side apart. The nut was still holding 250 ftlbs too.

Here's the shitty part. You need to be prepared for the hub to be trashed. The hub is most likely moving around inside the bearing and will show signs of galling.

The press fit between the hub and bearing is extremely tight and any wear on the hub will allow it to move and eat bearings. You can also destroy your knuckle if it's really bad.

Currently FTBR is the only place you can get hubs if you didn't know. There is also a few YouTube videos of Bruce talking about this same issue FYI.

I'd pull out the shotgun and do both sides like I did. My drivers side showed no signs of a bad bearing. When I pulled that side apart that hub was also walking in the bearing.

Here is what I found when my IRS came out.

You can clearly see the bearing was trashed.

Here is the passenger side hub I saved, the drivers side wasn't much better. You can clearly see the galling.

Exactly what mine looked like about 7 yrs ago when I took the knuckle and new bearing to ford to press

Here is what I found when my IRS came out.
