Hi, I bought an old 2008 duramax 3500hd 4x4 crew cab dually as a farm truck. I'm having trouble getting it registered properly. I believe it was a salvaged title and someone swapped a 2500 SLT body on the 3500 frame. Now my GVWR doesn't show it's heavy enough to be classified as farm use in my jurisdiction. Can someone tell me what the GVWR of this truck would be? From my research I think it's around 13,000 lbs. Thanks, Tobin

Nice looking Truck. I like the white wheel well trim instead of black. What colour did you paint your rims? I have an elevation so mine are all black. I find they don't contrast well in certain light and look cheap.

I can't see it being transmission related because of the audible change that occurs in V8 versus V4 mode. My tick is 10 times worse and more noticeable in V4 mode. Its almost like the some of the valves are of activating when they should be shut down? I also get the noise when pulling hard with a trailer sometimes in V8. i might try a heavier weight oil next oil change.

Mines been happening since month 8 of ownership. I’ve had all my AFM collapsible lifters replaced. Sorry guys but it didn’t change a thing. i have 70,000km on it now and it’s 2.5 years old. It’ll be driven til it’s sold like this. It’s not worth wasting anymore time.

Are you still satisfied with the steering shaft seal repair to solve the ticking V4 noise? I've had mine in multiple times and it's getting very frustrating! New fuel pump, new AFM lifters, and nothing fixes it.

could this vacuum pump failure be the ticking noise a lot of us are hearing? http://www.gm-trucks.com/forums/topic/193570-2014-chevrolet-silverado-1500-engine-failure/page-4

I did this last week and love it. unlock the doors with the fob now and the bed lights up! so easy. how did GM not have this option available in the vehicle settings. literally night and day difference!

Yeah, i'll try leaving my AC off for awhile and see if i notice a difference. In canada now we don't need AC, but i have a habit of just hitting the Auto HVAC button.

Isn't the AC compressor on the lower passenger side of the motor?

That is true. that is exactly where mine seems to come from.

Yeah, i've always thought exhaust too. but mine only happens now and then. that makes me think of the valve timing.

That is what mines sounds like as well. I can rule out the fuel pump and lines. I've had this all replaced and no difference. My AFM valve lifters have been replaced as well.

I can't stop trying to determine the noise in my motor at certain times. Since they replaced the AFM valve lifters, manifold, fuel lines and DI fuel pump, I'm starting to narrow it down to the variable valve train or the oil lubricating it. It only happens sometimes, under certain loads. that's why i'm leaning to the noise happening at certain valve timings. Since the seems to run fine, just has a loud knock sometimes, I'm wondering if this thin 0w-20 oil is too thin and causing these noises. When i start my truck in the morning the oil pump makes that groan that some people hear. Is anyone running 5w-20, 0w-30 or 5w-30 oil instead of the recommended 0w-20?

I think my engine is ticking again. i've come to accept I've got a lemon of a truck. What a disappointing experience this whole thing has been. Sounds like there are multiple major issues with these trucks. My first brand new GM vehicle and I won't be rushing back. I've had lots of good used trucks from them. $50,000 and it makes we want to .

My truck was in the shop 2 full days and the parts were $1896. Thank god for warranty.
