Default Tahoe Rear End Noise

Please help....I've got a 2005 Tahoe that over the last couple of months has developed a "clunking" noise that seems to be coming from the left rear of the truck. The noise only happens when accelerating from a dead stop or when coming to a stop. It only occurs at speeds less than 15-20mph. Here's the kicker, the noise may happen 5 times in a day or may not happen for a week straight. Nothing I do seems to be able to reproduce, also, 2 separate mechanics have looked at the truck and can't see anything wrong.

Anyone have any ideas as to what this could be, the noise is beginning to drive me crazy.

Thanks in advance

Is it a Limited slip differential?

Sorry, I should have said that is 4 wheel drive with traction control. Haven't had any issues with the truck in 4X4. I've checked all the u-joints and they appear to be tight.

Try a quick fluid change in the rear end and use the GM additive for Limited Slip!

I had a similar problem that I spent months trying to diagnose, than we pulled the rear apart and found a missing tooth in the ring and pinion.

Turns out I had a bad seal and dropping the boat in at the launch did me in. Entire rear was full of rust. Dropping the fluid like mentioned above will certainly give some indication of water.

I wouldn't put much stock in the "left side noise". These things are hard to pinpoint where the noise is coming from with all the acoustics under and around a vehicle.

Would a drive shaft slip joint cause a very loud noise that almost feels like the bottom of the truck is going to fall out? It is the strangest thing b/c once you come to a stop and start again the truck won't make the noise.

Could be a sticking brake caliper/slide. does one wheel get hotter than the others? If so, something in the brakes is dragging.

Not sure if one wheel is getting hotter than another. There really seems to be no pattern or ability to duplicate the noise. It is getting progressively louder and louder. I'm to the point that I just want whatever it is to break so I can fix it.

The problem might not happen when at a stop light. Unless you come to a stop, put it in park, release brake then put it in drive again.
Unless you do that, the worn joints, slip yoke splines and gears, etc. might all stay "loaded" until you go on the green again.

I agree with Mike B.....Sounds like you have a tooth missing from either main gear or pinion gear.... espicially if it has rhythm to it when slowing down or speeding up..I would take to a mechanic and actually have them drain and look at your gears in back if one is broke parts should cost about 300.. labor maybe 3-500.....I would take it to a good transmission shop (they usually do a lot of rear end work too) Usually not too difficult of a fix.... I would stay away from the stealership unless you still have a warranty. Pulling a boat is bad on rear end gears....mostly getting it out of the water from the ramp...It's almost a regular fix if you pull a boat long enough or have a high hp car. Mine was occassional but when it would do it....you knew it!

Thanks for the replies...I did have a bad left axle seal that was replaced about 6 months ago. Wonder if this could have contributed to anything.

Slip joint may be it. There was a TSB on crossmember clunking, but that's more up front. I lean towards maybe they didn't put enough of, or the right fluid in at the time of the seal replacement.

Leaking axle seal..had to pull the axle. Requires pulling the clip inside the differential to remove the axle. Removing the axle requires disassembling some brake stuff. Could even be loose lug nuts.

mine has done it since i bought with 60k miles- now at 190k and still does it. I was told to pack enough grease into the drive shaft and it would go away for awhile, but never bothered.

I have noticed that sometimes if I hit a bump or a pot hole at slow speeds it will begin to make the clunking noise. If I speed up the noise will disappear. Could this be the slip yoke? Sorry for all the questions, I'm not very familiar with these parts.

Lube your slip yoke. Problem solved. I've had this issue on every tahoe i've owned. Drop the driveshaft and lube the slip yoke.

Chevy has multiple TSB on this. A dealer can do this in 10 minutes if you don't want to. Super simple.

I talked to a dealer today and an independent mechanic and both said that the slip yoke is a non-serviceable part that can't be greased it has to be replaced b/c it is a sealed unit. Is this correct?
