Noise steering drag? Front differential? Auto 4WD

[Doubeleive]

have you checked the front diff for any metal shavings in the fluid?

Why not jack it up and put it into gear? The actuator going into the differential could be making this noise since it does not make noise engaged in 4WD. Could also be a yoke or u-joint but not likely. Where do you live? Maybe someone around here lives nearby and could lend a hand or see how the actuator is engaging via a Tech2???

that's weird usually they can just look it up with your vin number, there are a number of them on ebay if you shop around you can get one shipped fairly reasonable, prices vary a lot on ebay for the exact same part I guess some of these places think they have a gold nugget but others will give a decent price and shipping or even free shipping. you just need to verify the correct part, your local dealer parts department may provide it for you if there not *********. if you want to spend the money there are some places online that sell rebuilt units but there usually not so cheap.

I have a pretty good relationship with the parts department at the local Chevy dealership I spent a lot of $$ there, I will have to stop in and see if they can look it up, I have found they sometimes have a problem finding the correct part even by the vin, like when I needed a Drier for the ac they showed 2 variants and had to guess on what one it took. The LQK is a joke the guy who answered the phone said he didn’t know cars that well (what was he doing working the counter at a junk yard?)

Have you grabbed the flange from the front diff and moved it back/forth in/out to see if there any play? You may need to unbolt the half shaft from the flange on the driver side in order to feel any play as the half shaft is going to support and apply pressure which would give a false hope of everything being tight.

When I changed the hubs I tried both sides I didn’t feel any excessive play si has to be inside the diff

That’s not uncommon. There are two options for accumulators regarding our ac systems and unfortunately unless your familiar and can identify the differences then itll be 50/50 shot.

I had the same issue with other parts also like the Keyless remote I forget the other parts that we had to guess on I’m hoping the differential isn’t going to be the same so I probably have to find the id tag on it and photograph the RPP sticker in the glove box, I hope the front diff wasn’t changed before I owned it I know they have two different gear ratios used one for towing one for light duty use, if they put the wrong one in and used the 4WD I could have messed it up inside! I can’t figure out the vehicles history everything looks like new it even has the original exhaust that’s odd for a 01 with 270000 miles!

the number you called is probably answered by LKQ they have a nationwide database (or consortium) for all participating junkyards, the junkyards provide a list of what they have in stock to LKQ and what they want to sell it for, then when someone calls in they try to sell it to the closest person which is why sometimes when you call in they will have different prices from different locations but it sounds like whoever you talked to was a rookie.

Probably the staff at my closest lqk never was very helpful and I never saw them on the phone! Once I found a YukoI wanted to pull till parts from I saw blood all over the interior I told them and the desk clerk got nasty because I brought it up in front of everybody it looked like someone was shot in it and they put it out for parts, so I really look before I reach into any vehicle at this yard! It should have at least had a biohazard warning on it, the women just said real nasty “we follow all laws“ what ever that means? It was bad the drivers seat was covered in blood and there was splattered on the passenger seat the vehicle was not wrecked! I only saw something like this once before when I worked for a towing company in Florida that had a contact with the sheriff and FHP, when someone took themselves out in there car and I had to go get it, I remember the smell this vehicle in the lqk had the same smell but faint so someone or something died in it!

Here’s a GoPro video of the noise, you have to ignore the steering pump at slow speed and the buzzing (Its the wind vibrating the GoPro case) and wait till I’m on pavement the stone drive masks the sound,you can hear the clunks and such as I slow down and speed up, it sounds like the bearings in the cv axle or hub but it’s not they are new! Anyone recognize this it has to be in the differential!
