There was a loud clunking noise in back of truck, sounded like something loose. Looked, could not locate it. Finally found the issue after about 3 weeks. The bolt was broken off pin that goes through a gear and kinda wore hole where pin goes through. Was able the get a new bolt through the pin to hold it in place. Temporary fix. Kinda lost as to just get a used rear end or have rebuilt at cost of about 1600 dollars, which I do not have laying around. My understanding is a common issue with this. Too bad GM will not take care of the issues on them if know about it and recall them to fix the issues. Can break cause major accident or death?

Bought this 07 chevy classic brand new, complained to dealer about a whining noise in rear end they said it was normal, 3 months later whining is louder. dealer still says normal. at 52,000 miles a loud clunk not under warranty, now few days later grinding noise and rear end went out, took it to mechanic on trailer he said the rear end had no grease in it and the outside looked new with no signs of leak.

This truck came from the dealer or manufacture with no rear end grease. Now i'm stuck with 850.00 rear end replacement and 450.00 labor.

Bought the truck new from Bob Howard Chevrolet in Edmond,OK

clunking sound when I come to a start or stop. Sometimes after I come to a stop, about 2 or 3 seconds later it feels like someone bumped my rear bumper. I called the local chevy dealer and he said the slip joints are probably dry and need to be greased. I think these are sealed bearings?? It's still under warranty so i will have them check it out, but from the sound of similar complaints, it appears they can't do anything about it. Besides all that, the truck runs, shifts, and brakes just as smooth as can be. Hope they come up with a fix for this.

Bought the truck brand new. At a few thousand miles began getting a clunk when stopped. Had the truck in to dealer 7 times in the last 5 years to have yoke serviced with high temp grease. Transmission had to be pulled and seals redone at 12,000 miles. Clunk and stabilitrak failure light came on at 82,000 miles, 5 months out of warranty. Problem internal to motor, number three cylinder required replacement of cam and all lifters for $3800.00 plus $57.00 to relube the yoke. Now under 12 month 12,000 mile repair warranty on motor work. Own classic cars and fair mechanic, always ran mobil one in it after break in and service3d it didn't want to tackle the 5.3 L AFM motor as my daily driver and I have a day job. Very disappointed with this continual flaw/issue that they will no longer fix or address. Paid $40 grand for the truck so I will continue to drive and fix it, but disappointed in GM lack of acknowledgement and fix of design flaw.

I have the same complaint, feels like being rear ended, loud clunk, etc. I did some research, and found on another website that a man took his truck in and what a dealership did to his 07 Silverado had nothing to do with his rear end, yoke, or trans. Me being mechanically inclined thought for sure it would be definetly be all of those problems, but this suprised the hell out of me! They told him that it was actually his cam shaft, specifically lobe #4. Keeps breaking off and causing his engine to "foul up" especially when slowing down, gearing down when coming to a stop. They had replaced the cam 3 times under the warranty, but the problem still had exists. Soooo, this tells me that there definetly WONT be a recall anytime soon, and when the dealerships tell you that they are "greasing up your yoke", and sometimes even doing it for free, its because they arent even doing it at all!!! It is just a coincidence that your problem doesnt happen between dealership "greasings", believe me, I have never had my driveshaft, yoke, trans, messed with and just sometimes this clunking will happen, sometimes can go months without an episode. Either way, GM knows it is an Engine issue and not a Trans issue, therefore way too expensive, so they are trying to keep quiet. They need to take care of this ASAP or alot of loyal customers, me being a 12 yr old customer, will start buying elsewhere. IE Ford, Chrysler, but never foreign, thats not the answer! I have alteady dealt with my 02 pontiac grand am gt intake manifold gasket issue and that went bad, GM is a poor excuse for a car company.

I own a 2007 Chevy Silverado and for the most part have had very few problems with it except for one thing. Stop at a stop light and a few seconds later the truck lurches forward slightly and a thud is heard in the rear end. As like others have said, it feels like someone has ran into the back of you. I have had it back to the dealership 3 times for the same issue. I was told that this is a known engineering issue with the slip differential and no fix has been issued yet. Each time the dealer has lubed something (not quite sure what to this day) which has required removal of the drive shaft and several hours waiting for it to be completed. The dealership has done this at no charge each time but I am being told that this is not covered under the 100k drive train warranty and next time I will be charged. They did it this last time as a customer satisfaction issue since I am out of the full warranty period. The lube that the dealership does seems to last about 15-20k miles so it looks like I'll be trading it in before it starts up again! A shame....it's been a good truck otherwise!

Just bought a used 2007 Silverado. Had the same clunking noise after driving it for a week. GM said the same thing about the lube, added it and it went away. Now I see this problem is going to a continued problem.

Interesting thou, the mechanic at the dealership said this year was a problem and their is a fix but it would cost. So GM knows that it is a problem and should repair the 07. Wish someone could start a lawsuit against GM. GM doesn't pay me for the work hours lost going to the dealer.

Have taken it to the dealer twice. First time they said they couldn't find any problem, After complaining and taking it back they said they knew exactly what the problem is they get it all the time. They greased the yoke with supposedly special grease. Fixed it for about four months . Feels like someone bumps you on the rear end when you are stopped and slightly let up on the brake. Sometimes taking off there is a loud clunk like too much slack in transmission. Next time I talked to dealer was told "remember this is a truck it is supposed to make noise"

I bought a 2007 Chevrolet Silverado w/only 45,000 miles on it. It is still under factory warranty for the drive train. At about 47,000 miles it started making a clunking sound in the rear end. I took it to the dealership. They greased the yoke and the noise went away. Around 2,000 miles later the noise came back. Took it back to the dealership and they tell us that GM says that this is normal. They greased the yoke again. To make a long story short, I have taken the truck back three times already and I get the same response"It's Normal." I have called GM's customer service line and got the run around. I don't understand how this could be acceptable. If that is normal, I don't want anything else that GM makes. How many years has GM been building trucks? Looks like that they would know that that isn't normal!

I have been a loyal Chevy owner for 40 yrs. and this is the biggest piece of crap Chevy that I have ever owned. From day one, the rear end/ drive train has a clunk on takeoff. Have had it in shop 4 times and ready for #5. Sometimes you can just let off the brake and it feels like you've been rear ended, when the slack takes up. I am so pissed off, I'm ready to trade for Toyota Tundra. It has 31,000 miles and it's time for these SOB's to fix this truck! They haven't seen my wrath until my next visit!! Get madder just talking about it.

Should have went with the Toyota...............

This Is my second time with rear end clunking today it is as dealer service.I got the same run around about this issue take out drive shaft lube it with grease and good bye.It freaking joke 6 months later same problem.It GM nuts it sounds like to me it is it,s a bigger problem than was it is.To keep cost down they drive shaft out lube it and have a nice day.I think it is the gears in the anti slip but they are not telling anyone.Because cost factor would cost to much to repair under warranty.They might give you a story that the rear end fluid broke down.What does damage to the rest of the drivetrain that rear clunking.Not good we should all get together and file a class lawsuit against GM.To repair vehicle or replace I only have 16,500 on OD
