Clunk Going Into Gear - UJoint?

[JPVortex]

never mind the misfire is probably not the lifter. Long term fuel trims are 25% on both banks. Diagnosed as dirty or faulty MAF. Disconnected the MAF and fuel trims dropped to a much more normal level. Replug it in, they go right back up.

Hey y'all 2002 Suburban 1500 5.3, 4L60e with a 10 bolt rear. Noticed this clunk, particularly when shifting into reverse. Can hear it sometimes in drive as well. Sounds to me like it's coming more from the rear. Hard to pinpoint the source of the sound. Not sure if it's a ujoint that's starting to show its age, the trans mount, the trans itself, or the rear end. Don't notice anything weird when driving.

Sorry for the annoying exhaust sounds and the lifter tick, really noticeable from under here lol.

I have videos here:

Rear end(2 videos):

Front end:

Thanks y'all!

Can you move the shaft when in park on a flat surface. If so ASAP change them.
If you change 1 you change ALL. I saw a guy loose a shaft on the hiway once. Did that thing fly out. Like a torpedo spinning

Seems to be no slop in any of them! Not sure what the clunk is, probably the rest end. Vibration is the engine while driving, ended up not being the MAF. Probably the bad liter causing a slight miss.

You can have bad joints with no slop. They are rusted to H@&&.

That’s true, they’re definitely all original. 200k miles lol.

You can guarantee those needle bearings are bone dry.
