Ok so I have a 2000 5.4L v8 Fx2 and over the past year the driver side wheel bearing has gone bad at least 6 times! I always start to notice the slight squeeking noise it makes right before it goes out & sure nuff I pull it apart and the bearing fall apart!! It's not a expensive repair so I don't mind but why or what keeps making them go bad??? I've replaced front rotors and brakes. Next I'm doing both upper & lower ball joints. Has anyone had this issue? And why only the drivers side?? Also I do need tires & front end alignment. So please someone help me figure this thing out!!!

 

What kind of bearings are you using? I usually stick with national or timkin bearings they seem to hold up better.

 

You may want to check the see what the proper tourque specs are suppost to be (if you haven't tourqued the axle nut correctly). That could cause pre-mature wear.

Also if your running an aftermarket rim with very little back spacing, that also will add stress to the wheel bearings.

We carry the Timken bearings on our website with free shipping.

 

I use national I think and it's properly torqued. Only stock 16" rims. So what else could cause these issues???

 

Are you packing the bearing with grease before you put it in? There is a bearing packing tool that you can buy that is inexpensive or by hand is pretty messy. You need to make sure it is wheel bearing grease and not chassis grease. Also I pack the hub with grease before I put the dust cap on. Proper torque is essential. Tighten it until there is no up/ down play in the wheel then back the nut all 1/4 turn. Make sure you are getting the correct bearing and the spindle shaft is totally smooth. What size tires are you running? Do you do any off-roading? Alignment may be an issue but it would have to be pretty bad, I think you would have trouble driving it straight.

 

Yes I pack them with plenty if grease before install. Like I said I'm in need of a alignment pronto but can that wear the bearing so frequently and why only the drivers side? The alignment has the truck pull hard to the right!!!

 

Idk a about packing them with grease I know wheel bearings are usually pressed into the hub now so you end up buying a whole new hub assembly. Are your tires wearing oddly? As in the inside or the outside? I guess if you have a bad ball joint or something that's allowing pressure to be put on the bearing in odd ways that could be a reason.

 

I had a similar problem with my passenger side bearings. Had one get so bad the bearings themselves got so hot it welded together ruining the spindle. Mine partly from the stock wheels carrying 305/70 tires, but still, everytime it's the passenger side. I have no clue why
