Fullmaxx Posted September 20, 2015 Report Share Posted September 20, 2015 Just bought a 2005 Silverado SS AWD with 128,000 miles. Previous owner has already replaced the driver side axle twice thinking the first one was bad as well as the bearings. Also changed the fluids and additive. He stated that he has not heard this tapping noise for several months. As luck would have it I heard a tapping noise as I turned into my subdivision tonight. Sounds like someone tapping a hammer on a solid piece of aluminum. It only did it like 4-5 taps and then quit as I straightened the truck up. Any suggestions.

Downeast Johnny Posted September 20, 2015 Report Share Posted September 20, 2015 Welcome to the site and congratulations on finding your truck. From your description it sounds like the noise is happening while you are turning. The first thing that I would check would be the drivers side hub. Best luck.

Doughty08 Posted September 20, 2015 Report Share Posted September 20, 2015 Try to do it again and see if it does it under acceleration turning or just while ur coasting and turning. Try and power break it and see if it does it and let us know Quote Link to comment Share on other sites More sharing options...
8hnpSS Posted September 20, 2015 Report Share Posted September 20, 2015 is it only when turning? could be the steering shaft clunk issue that plagues these trucks. Quote Link to comment Share on other sites More sharing options...
Fullmaxx Posted September 20, 2015 Author Report Share Posted September 20, 2015 Thanks for the input guys. It did not do it while power breaking it. I also did a turn into the subdivision under acceleration and it would not do it. Yesterday when it did it turning into the subdivision it was a left turn and coasting.

Downeast Johnny Posted September 21, 2015 Report Share Posted September 21, 2015 Jack the wheel up off the ground, grab hold of the tire and jerk it side to side and top to bottom. See if you van detect any slop in the hub. Quote Link to comment Share on other sites More sharing options...
Fullmaxx Posted September 22, 2015 Author Report Share Posted September 22, 2015 No play in the wheel. But it did it again today when I hit a bump in the road. Quote Link to comment Share on other sites More sharing options...

Fullmaxx Posted September 22, 2015 Author Report Share Posted September 22, 2015 The noise did it again today while going down the road 3 times pretty close together. It also seemed like bumps in the road triggered the episodes. I was able to determine that it was possibly coming from the rear end of the truck. It's almost like the limited slip is trying to engage. The truck has 128,000 and still has original reared diff oil. I picked up some new oil today from the dealership and plane on changing it tonight. Any other suggestions? Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted September 22, 2015 Report Share Posted September 22, 2015 If it is triggered by bumps I would crawl under the truck and give everything a good look over for shiny metal. (Could be you've got a bad shock or sway bar bushing). Quote Link to comment Share on other sites More sharing options...
Fullmaxx Posted September 23, 2015 Author Report Share Posted September 23, 2015 (edited) I ended up changing the rear diff oil tonight. While I had it on the rack i did notice the passenger side bump stop was missing. Nothing else was out of place or any noticeable damage to anything. Double checked to make sure the front wheels had no play in them. It made the same noise while driving home.

Doughty08 Posted September 26, 2015 Report Share Posted September 26, 2015 How did the fluid look? Quote Link to comment Share on other sites More sharing options...
Fullmaxx Posted September 29, 2015 Author Report Share Posted September 29, 2015 It was black. Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted September 30, 2015 Report Share Posted September 30, 2015 No chunks or anything to lead u to believe it could be the rear end? Just know when spider gears start loosing teeth it pops when turning but if it's when going over bumps mainly then I'm at a loss brother and like said before look for shiney metal where parts could be rubbing together. Let us know what u find Quote Link to comment Share on other sites More sharing options...
Fullmaxx Posted September 30, 2015 Author Report Share Posted September 30, 2015 Nothing but dirty oil. No metal shavings either. I'm just going to hammer down and it will show itself one day for sure. Thanks guys for the suggestions. Quote Link to comment Share on other sites More sharing options...
