Have you checked the wheel hub bearing assemblys for play? Common issue on these trucks my first guess would be one of yours has gone bad.

Need to change the power steering pump on my 09 silvy 5.3L. It is leaking and whining during acceleration. Any particular brand you guys recommend? OEM? I'm reading mixed reviews on the cheap refurb units a lot of people saying they are noisy. Thanks for any input! Sent from my SM-N975U using Tapatalk

So I'm about to change the oil cooler block off gasket on my 09 5.3 Silverado. I have the Felpro oval gasket. One of the sides of the gasket is raised more than the other. What is the appropriate orientation? Does the raise point towards the inside of the block off cap or toawrds the block? Thanks! Sent from my SM-N975U using Tapatalk

Yeah as mentioned above sounds like your bulbs aren't seating well. Also check the condition of you connectors really well. I know several people including myself have had problems with these trucks burning up the low beam connectors. Not sure if it is a short somewhere or what but I've been through several. I would have the same issue sometimes they would decide to work and other times they wouldn't.

Yeah sorry haven't updated. Grease was on wheel side. Got CV axle replaced and tires rotated and no change. At this point I'm fearing something is going on with the diff. I will take you advice for checking the diff and post results. Sent from my SM-G965U using Tapatalk

Did you check the connector that plugs into the bulb really well for damage? I had a low beam go out and thought it was the bulb, switched it out and still didn't work. Then I took a good look at the connector and realized something had caused it to burn up and it melted. I don't know what the heck caused it but I spliced in a new connector and haven't had anymore problems. You say you have a little bit of power to the socket so this probably isn't the issue but I would give it a good look if you haven't already.

No I haven't heard any clicking/clunking while turning but I have noticed on a couple of occasions I have the sensation of something clicking in the front end through the gas pedal but not while I was turning so maybe not related IDK. Usually while I'm driving straight at lower speeds. I'm gonna get it checked out to be sure. Hopefully it just needs to be cleaned and have a new boot installed then packed with grease.

Actually might have found my issue. Was looking at front end and noticed drivers side cv axle shaft was black and had grease all over it where it had blown out. Passenger side shaft was clean. You guys think this is the likely source? Sent from my SM-G965U using Tapatalk

Yeah I thought it was the hubs I have just had both replaced and it didn't go away. I will check out the ball joints however as the truck has 140k and has never had ball joints replaced to my knowledge. I'm not hopeful it is in the tires as I have owned many sets some wearing unevenly and have never heard any noise like this coming from tires. Sounds more mechanical in nature but maybe I will get lucky.

As the title says I have a loud humming in the front end of my 09 silverado 4x4 which is at its worst between 45-55mph and upon deceleration. It seems to be coming from the front left side of the truck as the noise is not as audible when sitting on passenger side. It is not really that noticeable at other speeds. I chalked it up to wheel bearings and replaced both to no avail. I am going to have my tires rotated today to see if noise changes position. I have noticed scalloping on some of my tires but didn't attribute it to that because I have had worn tires before that have never made noise like this or this loud. It is a fairly high pitched hum/whiring noise. Tires are 285/65/18 bfg a/t 2s. I will post results after rotation today but do you think it could be a tire? If it is not a tire where do I got from here? CV axles or front diff? Could anything related to the braking system cause this?

Well I have a bad wheel bearing/hub assembly in my 09 Silvy and I'm probably just going to go ahead and change both of them out. Seems to be a lot off different brands out there just wondering what you guys have had luck with? I was thinking AC Delco or Moog those are obviously a little more pricey. Any other brands you guys like to use?

Ended up being the junction box. Swapped out and back in business! Actually don't even know if old one was bad. Had some corrosion or crap on one of the pins might have been issue. Just changed out while i was at it. Thanks for the pro tips! Sent from my Pixel XL using Tapatalk

I didn't get the chance to check this out yesterday will be doing it today. Thanks for the info!!

2009 Silverado and neither the brake nor turn signal lights are working on the taillight of the drivers side. I have tried changing bulbs to no avail. I have also checked fuses (all good) and inspected wiring to the best of my ability (no noticeable damage). Turn signals on headlamp work but hyperflash. Any other common areas of failure that might cause this? A switch or some type of relay etc somewhere? Any input is appreciated.
