Rear diff / tranny clunk

Rotzilla · Oct 19, 2011

After stopping my 09 would make a clunking noise that would cause to truck to jump. It wasn't very loud or vicious, just annoying when coming to a stop.
Dealer updated some softwear which partially resolved the problem.

I thought this was an isolated issue, however my 11 is doing the same thing.
Is everybody experiencing this?

Don't think I've heard anyone on here having this issue. I'd say take it to the dealership and let them look at it. I'm presuming it's under warranty.

Rotzilla · Oct 19, 2011

Yes its under warranty. I just can't imagine I'm the only person, two trucks two years apart with the same issue. Must be the Co. special. LOL

Maybe its the driver. :********:

Im just playing, hope you get it all taken care of. How many miles have you put on the truck as its a 2011.

dang that's really weird, hopefully they'll fix it for ya

The only odd noise I have (other than shoddy interior assembly) is a popping noise on off camber driveway entries. I'm pretty sure it's the rear coils almost falling out.

My 2011 does not do this, i have less than 3,000 miles though

I got 14k on mine. It's quiet and smooth right now but I'll have to pay attention to it now and see if it's doing anything. I do know there wasn't much effort taking things apart in front to do the HBS level kit.

my 09 & 11 both did it from the day they rolled off the lot.
Haven't taken the 11 in yet.

Gone now pinion bearings or powertrax must have caused it.

Every silverado I have owned did this. GM makes a special grease for it. You pull out the driveshaft and grease the splines on the part of the shaft that goes in the tranny. I do my silverado about once a year and it fixes it.

I will be curious as to what the dealer says.

Since day one I have noticed a clunk. It is strange, not like the GM trucks. After stoping ( like a second or two.) feels almost like someone bumped you from behind. I have turned off the hill assist and nothing changed. I have Know idea what it is.

Look up driveline or axle wrap.

I think I remember a thread about this a long time ago on my old forum, how credible the information is I don't know, but if I remember right, people were saying it was something along the line of the torque converter unlocking that caused that clunk. I know my truck does it every now and them and seems to become more rare of a thing to happen as I put more miles on it. The way I've always described it is like having a bowling ball in the bed of the truck and a second or two after stopping, it hit the front of the bed.

People had said to pretty much ignore it unless it becomes violent and like I said, mine seems to be going away as I can hardly remember when it happened last. But under no circumstances am I saying not to take it to the dealer, it's always better safe than sorry especially when you have a warranty

Just turned 4k and is still doing the same thing consistantly. Oh well. If it pukes its guts I'm still under warranty.

The Gen2 trucks were notorious for this when the Torque Converter Control Circuit was malfunctioning.
