1999 chevy tahoe squeak/scrunch left front

[kyle1!]

My 200k 4x4 LT trim 350 chevy tahoe has developed this squeak/scrunch when you take off from a stop. You can be going straight or turning it does not matter. Changed differential fluid last week and it was mostly clear with no grit that I could feel. Front end is tight after pulling/prying on the various pieces. Runs down the road just fine but the squeak/scrunch makes me think something is about to grenade. Thanks for the help.

likely have various body connection points or subframe areas rusted out.

I have had sway bar bushings make that noise when they dry up.

Have to distinguish whether it is rotational or suspension related to better narrow it down.

Tahoe is not all rusted out believe it or not. I put on a rebuild front end kit at the beginning of summer with new bushings so they are not old. That kit made no difference. I do have some suspension squeaking but I want to say this is rotational. I looked at the driver side drive axle yesterday and it has a layer of crud between the boots that you would have to remove with a putty knife. I can't see a split boot but will crawl under for a better look this weekend. Thanks for the help.

Grease on a boot is a good place to start looking. Also Jack up the front end and give the tire a good shake up and down/side to side to check for worn wheel bearing, ball joints, etc. May have to get a long bar or pipe for leverage.

All the front end stuff has been replaced..ball jts, wheel bearings, end links, tire rod, idler arm etc. It does need a new steering box. It will stick on left hand turns there. I will start with the drive axle.
