Front wheel bearing hub assembly

Front wheel bearing hub assembly

PostBy: gaw On: Fri Mar 07, 2014 10:22 am

I have a 2007 Hummer H3 that started making noise in the frontend. Last night I lifted it and found a lot of play in that wheel, today I plan to remove the wheel and take a closer look. I fear it could be the bearings so the question is this. What brand wheel hub has anyone here had good luck with as a replacement. The AC Delco is about $200 and would be same quality as what just wore out if in fact that is what is wrong. I can get a Timken for just over $150, country of origin unknown. I found cheap aftermarket replacements starting at about $70 most likely coming from China.

I am leaning towards the Timken if that is what I need unless anyone can talk me out of it.

Timken is good. We replace a fair number of the bearing/hub assemblies on the plow trucks. You may have a local bearing/drive shaft shop? Your local parts store will usually offer two price points. The lower being the china cheapo and the higher
being the good one. OEM are fine, but pricey. Get the good one if you are planning on keeping truck.
Many will lube bearing once a year or so as pm. Usually a chain oil is sprayed into bearing threw abs sensor mount while turning hub. Just a coating, not too much or you will get funky abs readings. Good Luck!

If it's like the rest of Chevy's/GMC's trucks, might as well do both now. The other side is only miles behind. :roll:

Well the right wheel had so much play it felt as though it was about to fall off. After removing the wheel it didn’t feel as bad because of the lack of leverage but the slop in the hub is noticeable even shaking it just by the studs. I did the same on the left side and found play over there as well, only about half as much but any movement is unacceptable so it looks like I’m in it for two front hub assemblies.
I think I will give the Timkens a try and save about $90 for the pair. The originals made it about 85,000 miles which I guess is about average or a little less. It seems that so much of this type of stuff starts to fail at or near that magical 100,000 mile mark, at least this is how it seems to go for me.

That is tight quality control standards. :lol:

Interesting, never heard of that before. What do you have to lose though? It would be simple to do when rotating tires, an extra 10 minutes.

On today's vehicles this "lube" is useless. ABS rings are usually on the drive axle, which is external to the bearing.
Most bearings are sealed hub assemblies, and or, rarely ever incorporate the ABS ring.
Look it up on line. I'd go with Timken, or mexico/other, but never china. Seen too many failures/poor quality of Chinese parts.
I've got a few China stories.

Timken is my vote. Done a few and always trusted Timken quality when I had a choice.

We are running ford rangers and jeep wranglers, 2005s and up 4x4s-no external abs ring, sensor plugs into the hub it self. Pull it and you have access
to the bearing surface. The "unserviceable" part can now serviced. No clue on GMs as I have never
owned them.

I did both sides on my 1999 Silverado last summer. I had a bad code that said both wheel speed sensors were bad. I read on the truck forums that it is best to just replace both bearing assemblies, they come with new sensors. They were the original assemblies with 120k on them. I bought them from NAPA. They had a cheap and a better one. I bought the better one that the shop I go to recommended. You will need a socket that is something like 32mm and a good torque wrench. I read that the torque specs are very important. No guessing there. Check the forums.

I was employed by Timken in Canton, Ohio during the eighties. We had a Plymouth Horizon at the time that needed front wheel bearings. I was able to purchase them at work and replaced them myself. As I recall, I had to get a local shop to do the press work for me. I don't think that you could beat Timken quality.
