New front end noise?

[02suburbanZ71]

Do you have a floor shifter for your 4WD? I had that same type noise on a other truck I had and when I grabbed the floor shifter to see if that was making the noise I felt it in the shifter, and when I moved it to the right or left cant remember the noise went away so all I did was slightly bend it over some and never had a problem.

No its auto trac [emoji19][emoji19] i wish it was floor lol

I got it back from the transmission shop and they said they cant locate the noise- even on a 4x4 dyno. They said it might be the front diff but im NOT throwing parts at it. What do i do? I have had it at 2 different shops 4 times. HELP lol they have no idea what it is

At that stage, I'd just run her till something busts. At least then you'll know exactly what it is. Sounds like a wise-assed comment, but it's true, unfortunately.

 

I've had a bad bushing or bearing in the front diff since 45-50k miles that wiped the seal out, so it slings gear oil everywhere by the spinning CV. Been waiting for that to grenade on me on a -10° day, while stuck in 2' of snow ....

 

The incessant clunk I've got (since new) at light pedal during the 1-2 upshift has been getting much louder as of late. 73k on the clock now. I'll be shocked if this thing makes it to 100k without exploding.

 

I miss my 40 year old cars that I didn't even give a second THOUGHT about getting me where I need to go. I guess this is what they call ... "progress" ...........

Drove the car 60 miles to downtown chicago to tramcar transmission. They are the best shop in the chicagoland area. Went on a test drive. We both drove and he noticed something too in the front. He said it sounded like the front diff was loose or front diff had play. How is this related to a grind whirl noise only in 4th gear? They are going to investigate and call me this week
