I have a 2003 Chevy trailblazer also. I replaced the bearings and had the noises still ..4wd does not work.. Found out it is the differential. Part is cheap however very labor intense. I dont even have 100,000 miles on the vehicle. I will never buy a GM product again....Hope this helps everyine.

Just got 2003 tb V8 with 86,000 mi back from the shop. Had loud growling noise from front differential with large amount of metal in fluid, an on-going problem since 35,000 mi. Had shop install salvaged(Junk yard) diff, 550$ for diff and 900$ to install. Growling gone but now sounds like wheel bearings are going. Have I traided one problem for another? Also, no heat from rear heater, rear Air and fan work fine. Any ideas.

I am having the same problem, my 04 trailblazer is making that siren noise and its annoying. I took to the dealer and he said it was the shaft and it should be replace or I'd end up on the side of the road one day. If this is happening to so many of the 04's could this be a manufacturing problem and maybe we need to go to Chevy. This problem is going to cost me $2000+ and I am not happy about that.

I have a 2005 trailblazer with 50000 miles. I have owned over 40 vehicles in my life and have been a GM fan all my life. After owning this vehicle with all the problems I have had I will try very hard not to buy another GM in my life time. I have a speedometer that tells me the wrong speed, a fan switch that only has 2 speeds, A rear hatch latch that would not unlock and now an annoying howling from either a wheel bearing or differential. Pissed off? Yes. I do though have a Car Cert Bullsheet. Obama should have let them crash and burn.

I have a 2006 Trailblazer with around 40,000 miles. I'm hearing a clicking noise like there's a stone in the hub cap, but I know its not that. Is anyone else hearing that kind of noise and do you know what it is?

My 2003 Trailblazer 4wheel stoppedd working, turned out the actuator was not moving far enough to engage 4 wheel. I had an excellent machanic who instead of selling me an expensive repair, made a shim on the actuator and it has worked perfect, for under a 100 dollars. Am still struggling with thumping noise tho in front end, not in budget right now to have looked at; never mind fixed!

I have a 2004 Chevy Trailblazer LS 4x4 and I have this noise coming from the right front tire which I thought was just the plastic piece over the tire well flapping in the wind because it's broken but the car is at the dealership as of yesterday and he calls today and says it is the bearing carrier assembly inside the axle which at the GM parts warehouse is $2300 without labor. Anyone know where I might can find a used part still in good shape? I can't believe after reading all of these post that everyone is basically having the same trouble and all within around the same year vehicle. This really sucks.....

too the last 2 messages,i have my 2004 trailblazer in the shop now with same problem. Its been a good vehicle and has only 62,000 miles. Carrier bearing which is a major operation itself. my total bill will be about 2400.00 but that includes a couple other issues not related and thats with a used carrier bearing. i am getting a 12 mo 12,000 mi warranty with it which is good. new one would have been alot more. sounds like its an issue with this vehicle.

Please replace both wheel bearing hubs, they come as a complete kit with the abs harness wire and is about a 2 hour change to each side. The noise can seize and lock your wheels up and is very unsafe, especially during this winter season.
If you'd like to make sure that it is your wheel bearings, just lift the front end of your car up. Take both of your hands and place them 12 o'clock and 6 o'clock degrees, then tug and pull and see if there's any swing. If the wheel moves, the bearings are out of place. The ball joints can also cause the wheels to move as well so be sure to check your upper and lower ball joints and grease them back up as needed.

Dealer told me this is normal for the brakes and sway bar link. I bought this new. I take good care of my trucks. Gmc rep says so what more or less anyway. They don't care. I also have has to replace the rubber around the rear plate, left tail light, molding on driver left side where controls are at. Strunt on rear lift window. Scared to keep it...
I got smart went back to a Ford F150. Been there for a little over a year now. Chevy doesn't care or do I.

i have an 06 trailblazer with extreme noise on the front end. metal in oil and oil smelled burnt from the front differential. i have read that the differentials are some what bullet proof. the passenger side cv shaft i pretty dry as well. when put into 4x4 the vehicle had a drag so bad it would actually stop the vehicle. i almost have the differential out and then plan on opening it up to repair what i hope will be an easy fix. any comments would be greatly appreciated???

I just had to have the front differential rebuilt in my 04 TB w/60K miles. $2300. (including 10.5 hours labor). The mechanic said it was a nightmare to work on. Dealer here does not even stock the parts, so an independent shop had to do the rebuild. They informed me that an updated bulletin calls for changing to a lighter weight synthetic gear lube. The original lube was too heavy to keep the differential lubed. (Maybe this is causing all thse failures. Also I am told that even in 2wd, one front axle turns. (Maybe explains why some of thse letters are about intermittent noise from turning left or right. By the way, the front differential is hardly bigger that your fist. (Not what I would consider adequate for a truck). Good luck with all your TB's out there.

05 trailblazer 80000 miles has a growling in front end thought it was worn tires, so i replaced them with a new set of generals. still have the noise. almost sounds like a jake brake when deccelerating. so has to be the wheel bearings, right? WRONG!! i replaced the wheel bearing assemblies still have the noise. It must be a cv axle or the front differential. GM is crap and ive owned them all my life. I dont have the $$$ to sink in ti this junk pile. Toyota here i come!!!
