06 h3 100k miles grinding, groaning clucking in floor on drivers side

[Happy Hummer]

As stated in title.....
06 h3 104k miles
Gf's. ..lol again ugh!

First what works:
Drive 1 2 3 & reverse
4 hi... 4 hi lock .....4 lo
Brakes were thoroughly cleaned, replaced last summer.
Shocks were replaced last summer.
Transfer case actuator replaced last fall.
Transmission fluid filter, gasket & fluid changed last year.
All fluids check full and clean.

Symptoms:
Just started today.
Grinding rotational rubbing sound under h3.
sounds similar to the noise one gets with stuck caliper but no signs of such a problem.
There are signs on dampness from trans weeping fluid again but fluid is full. This is the same as before we changed the gasket and filter. Probably loose bolts or dry gasket.


104k miles I'm wondering where would be a good place to start to diagnose this trouble.
Loud enough to clearly hear in cab of truck but intermittent.

Thanks as always

My first guess would be the CV joint on the front drive shaft.
If I remember right is on the transfer case end of the shaft

Check to see if the heat shield from the passenger side of fuel tank has come unstuck and is rubbing on drive shaft. Happened to me last week and took a few min to spot that. Otherwise, CV or wheel bearings are my guess.

I'll check the heat shield although inspection from under vehicle early today showed no loose parts. Will look again.
Any other thoughts as to what it might be.

Get tires off the ground and get under it while it's in D.
Possibilities. From drive slip joint, CV axles

And drum roll...... the winner is front left passenger hub. Gf decided to take it in for inspection and that is what they recommended be replaced. There price way to high. I reccomended she drive home slow and will replace next week. Have to order the part and wait for delivery. Well lucky this aint my 1st time at this rodeo.

Update:
Old hub and all associated hardware removed today. It's a bit of a stinker but it is doable.
Part should be here soon.

My hub is busted too. I've been saying on hear for the last few months I'm going to get around to replacing it... has anyone tried these out? http://amzn.com/B00LFL862C I could do both front hubs with these for the price of one timken...

We chose Timken.
Got it in today. FedEx dropped it early afternoon. Already installed. Oil changed and new filter.
