Think I have a bad wheel bearing. Moog or Timken?

First off, apologizing for the long post. Not even sure if this needs to go in this forum (couldn't decide which one to put this in).

Who makes the better front wheel bearing/hub replacement? Moog or Timken? I always thought Moog made the better suspension/steering parts and Timken had the better bearing components.

I think one of my front wheel bearings is out or going out. What do you think? Here are my symptoms.

1. Getting a squeaking/metal on metal sound
2. Does not happen until I’ve been driving for about 10 minutes. If I stop somewhere (grocery store, etc) it won't do it for about 5-10 minutes after I start driving again.
3. Was not happening every time I drove but getting more consistent (and a little louder)
4. Usually starts around 15 mph and can hear it up to about 35/40 (noise loudest at 25-30 mph). Anything after that the road/wind noise seems to mask the sound
5. Noise post pronounced when driving straight. When making a sharp left turn the noise goes away. I did a zig-zag pattern in my neighborhood at about 25 mph and the noise went away whenever I made the left turn and came back when going straight. Making either a right-hand turn or right turn doing the zig-zag pattern, the noise is still there.
6. There is no play with either front wheel but I have read that a bearing could still be bad even if they are tight.
7. Definitely sounds like it is coming from the left side of the truck. If roll down only the right window I can't hear it, but can hear it very clearly with the left window only down.

I was reading that you can test which one it is by turning while driving. If the noise goes away when turning left, it’s your right bearing. If it goes away when turning right, it’s your left and that it is taking the pressure off the bearing. Is that true? I would think if you turn left and it goes away, you take the weight off the bearing since the truck leans more to the right and puts more pressure on the right bearing.

Sorry for the long post but wanted to get as much information out there as possible. What are your thoughts? Bad bearing?

I just replaced both passenger and driver side on my wife's yukon. I went and bought the ac Delco Oem wheel hub assemblies and they have timken bearings.

oems are Timken

 

I was going to ask if anybody knows who the OE supplier is for the AC Delco hub assemblies. Rockauto has the Timkens for $113 and the AC Delcos are $209. Looks like I'm going with the Timkens especially if they supply AC Delco with the hubs. Why would I pay $90 more for the same bearing/hub assembly?

I picked up some Valvoline Durablend grease for when I get to do my hub replacement but then realized I have a can of the GM grease (Part# 12345879). Should I use the GM grease or the Valvoline?

Is the GM grease a good grease or would Valvoline be an upgrade? The manual says to use the grease on Front Axle Propshaft spline.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
