Clunking when taking off

[Saucy_Walnuts]

So my 03 Yukon 4x4 has developed a clunk when taking off after taking my foot off the brakes. It happens 1-2 seconds after. Ive checked everything i can think of nothing feels or sounds loose. Ive checked calipers, everything steering wise, torsion bar cross member mounts, trans mount (its wore but sound isn't coming from there. It sounds like its coming from.the front), CV axles. Bearings, Ujoints, shock mounts, steering shafts to the gearbox, all the rear suspension parts. Ive smacked everything i can think with a hammer and even had my wife drive up and down the driveway. I can't figure it out. Its driving me crazy. Lol anywhere else I should check?

I had a dry slip yoke that needed greasing. At first I thought it was a pinion bearing so had my rear end rebuilt. Yay parts cannon!

It sound like this?

Similar but its just a single clunk. Not multiple. I did just replace my front shaft. I greased it. I may need to grease my rear shaft. And it does not do it on bumps. Only after hitting the brakes.

I had a clunking noise when accelerating. Ended up being a broken rear u-joint cap.

Does your truck have front differential mounts? If yes, that is probably the source of your single clunk noise.

Probably a u joint worn or trans mounts bad.
