Currently my brother is looking at a 2009 Chevrolet 2500hd 6.0L with 70,000 miles on it, i am in the process of helping him and the other day i took the truck to a friends shop and we spent about an hour going over the entire truck and it is extremely clean barley any surface rust everything is Immaculate underneath, no fluids anywhere and the front end is tight. It however was plowed with. We were able to contact the owner of the truck and asked one why he traded it in and to what extent he plowed, he only traded it in because he wanted a diesel and he also only plowed his driveway with it, which is very believable. A extra perk to is the guy had dual batteries installed. Now here is the only problem, and i am curious if you guys have ever heard of this happening, when i test drove it i went into a dirt/mud parking lot and put it 4 wheel drive and made some turns and pulls and what not to check to make sure it was all good, when i did this there was clicking my thought was cv shafts. So i told the dealer to check it out and there tech just got back to me and said on the driverside, cvshaft/hub there is a lateral support bracket that has developed hairline cracks in the factory welds, and when the torques transfers through this is causing a clicking noise. i am waiting for pictures from the dealer and will post when i get them, but i am concerned this maybe a potential for disaster, i also have no idea what bracket they are talking about. Any help is good help, the previous also stated that he had the oil pan resealed and transmission lines replaced why idk but everything is fine underneath with no leaks so i am not really concerned about those. Thank you very much

Sounds like stress from plowing. Happens to the best of us.

if it is fixed by a certified fabricator that is at the dealership do you believe everything will be ok. Trucks rides great and four wheel works great just clicks so i cant imagine it being a problem. I also have no doubt its from plowing just wondering if it is common.

it will feel like the diff is welded during tight turns. Is it a clicking noise, or tires chirping from the driveline binding?

no no im sorry that was a bad representation of the problem the truck drives fine and feels great but when in four wheel drive there is a distinct loud clicking noise that dealer is telling me to be a weak weld at a cross support bracket. It drives and feels great, the diff is not welded and the tires dont chirp. The only binding i feel may exist is in the cvs but the dealer disagrees. The only thing that is noticeable noise, sorry for the confusion.

Does it click during tight turns in 2wd?

Quick question (sorry about the diversion), is the 2nd battery different from the primary?
(as in when I get a new batt can I just move the old one(still good) to the 2nd spot and get the harness?)

Thanks

i believe people recommend getting two new batteries just so you know the voltages match but i am sure it will still work just have to setup the wiring for it.

I was going to say it sounds like a U joint issue if it's making a loud clicking while turning sharply in 4wd, but if they say it's a cj joint bracket then like beckmand78 said, probably caused by stress from plowing. Would not worry too much, especially if the dealer fixes it and you no longer here anything.

It's probably too late to have any important info here, but IMO it sounds like a CV shaft. U-joints are in line with the truck, so they wouldn't change or create noise when the truck gets shifted into 4WD. The CV joints have "cages" & if some piece of metal is busted, the bearings will no longer perform as they should. Then, that side wouldn't pull when you push the throttle. As far as I know, there is no visible bracket that a technician could see & say is cracked. Now, unless GM added some parts starting with the '07 models, this is the information that I recall from all of my years looking at the undercarriage of GM trucks.

Here is a picture of a CV joint. Notice the ball bearings? If a crack happens in the metal between the bearings, then it could break off & the bearings would fall out, rendering that shaft useless. But, these joints are covered by the rubber CV joint boots to keep dirt/crap out of the grease, so unless the boot is busted & the grease was slung out, the technician won't be able to see it.
