97 gmc sierra making a loud humming noise!

Recommended Posts

When I accelerate it gets louder. 30 to 40 mph is the worst. I almost don't hear anything at 60. It is definatly coming from the front. I just had the tranny rebuilt a year ago. Any thoughts? Thanks guys

Depends somewhat on the quality of bearing you use. A premium one is about 200 at Napa and the standard grade one is about 125 . Add 150 or so labor depending on where you take it and it should be 275 on the bottom end and maybe 400 or so on the high end.

You never said if this is a 2 or 4 wheel drive, If its 4 wheel drive make sure both hubs are locked out. If one is locked in the other out the dif. will make a real loud hum. If its a 2 wheel drive the above posters got it pegged.

Thanks magyver...it is 4 wheel drive. I have put over 100,000 miles on it and never replaced bearings. I sure hope it's not something to do with dif. Mine is push button 4 wheel drive so how could one lock and the other not?

Does it make the noise all the time, or only in 4wd?

If it only makes the noise while in 4wd then it is possible it is a bearing in the front differential, if not then again the hub and bearing assembly is the most likely.

I'm not quite sure what you are asking about one locking and not the other.

When the veical is changed from 4 wheel drive to 2 wheel drive the front hubs in center of the rim, or wheel unlock, the axle, the dif. and the drive shaft do not turn then. The hubs lock and unlock automaticly. After a period of time rust and dryed grease will freeze one up and it will either be locked in or unlocked all the time. When one is locked and one unlocked the diff. will be spinning 2 times as fast as normal. We had this happen on a trip up north, the oil in the diff. got so hot it started to smoke before could figger out what was wrong. It got so hot it ruined the seals in the diff. I changed the auto hubs to manual lock outs.

What you are saying can be true of older vehicles that used manual or auto locking hubs. There are however no manual or automatic "hubs" on this vehicle, the locking and unlocking occurs in the front differential.

Both front axles are live and turning all the time, but do unlock from the differential.

    • Thanks big d, I wanna give it a shot as well!!
    • The recipe I sort of followed said to cook it for 15-17 minutes at 350 but it took about 25-30 minutes to get the potatoes done even though I sliced them thin.   It's worth a try. We do a shrimp boil sometimes when we go camping with a group. I do it in the turkey pot and follow the recipe from Old Bay seasoning w-e-b-s-i-t-e except I like to add some chicken as well. It is very good and everyone loves it. 
    • How long and what temp did you cook this? Looks really good I want to give it a try now.
    • Chops, brats, asparagus, onions and mushrooms in the foil and a little Malbec
    • Shrimp boil in foil packets on the pellet grill. Potatoes, corn, Andouille sausage, shrimp, lemon slices, butter and Cajun seasoning. I usually use some Old Bay in my shrimp boil but I was out and didn't know it until I started putting it all together.      
    • Hello from Sunset Lodge!

      In Minnesota, walleyes and pike have been found using crank-baits on the south side of Oak Island.  Walleye have also been caught pulling spinners in 26-30 feet using gold and green.
       
      In Ontario, walleye have been very active using pink and orange jigs on the breaks of reefs or casting shallow crank-baits in 8-12 feet by rocky shoreline points.  A good mixed bag of smallmouth and pike have been found with the walleye as well.
       
      Musky fishing has really picked up with lots of fish over 40+ inches.  Fishing sand and weedy bays near rock reefs have produced well using buck-tails, small crank-baits and top-water baits. 

      Until next week!

    • Looks like a great summer time meal! 
    • That was my wife taking a Snapchat vid of the kids, my daughter took that picture..  steak night is probably my favorite night, but taco night is a close second lol
    • At the all-star break and man did I blow it with the predictions lol.   Other than Rosario and Escobar not really much to get too excited about.   Nice home-stand before the break but its already been a big disappointing season. Of all the late 90''s  teams that were just awful and then the recent  90+ loss teams repeatedly over and over, this years team has to be the most frustrating of them all. Definitely a regression.   Buxton/Sano I dont want the team to give up on them but good grief. After some progress last year I think everyone was expected big things from both of them. I would say give up on them but players like these always go on to shine somewhere else when the Twins let them go.   Mauer has been ok, nothing great but good to see him back hitting again after his stint on the DL.   Morrison dug himself too big of hole to get out of with a terrible start at the plate. A few signs of power but not enough.   Dozier is losing millions with a bad first half. So much for him signing a big deal somewhere else and the Twins getting something for him if he is traded.   The new pitchers Odorizzi and Lynn haven't been great. Gibson has been better than expected but too bad he cant get any run support he has pitched well all year. I like Berrios, good young pitcher still making improvement. Its too bad Santana hasn't been able to get back up and contribute yet.   I hope they don't make any foolish decisions and trade and try to make a run. They don't have a chance at the wild card and even though Cleveland isn't completely dominating I don't see the Twins overtaking them in the division.
