Maybe you can help me...when I am decelerating around curve and then start accelerating, I have this clunk in the engine. I was told that the drive shaft needed to be lubed but this was done in past and did not help. Any ideas?

Re: clunking noise w/ acceleration
Ya know it sounds like one of the U-Jonts in the front drive line to the front wheels has failed or even one of the driveline U- joints is either Dry and lost its bearings and is worn out,
One of the easiest ways to make sure its not the engine is while driving down a hill put the car in neutral, turn off the engine coast down a small hill and turn to either direction and see if you still hear it , if you still hear it its gonna be somewhere in the drive lines, becareful you will not have power steering or power brakes with the engine off, but you can restart the engine inn neutral at any time . Please let me know.

suggest that you talk with a diff reconditioning specialist center
if you have excessive pinion to ring gear clearance the diff will be making terrible noises not a clunk
what you have is worn side gear washers in the diff carrier and that is not essential to repair unless you get diff noise on turning corners
All diffs have play in the diffs that most people say is pinion /ring gear problems when it is not
the clunk noise comes from engaging a gear and the diff housing reacts to the load ( radius rod bushes , stabilizer bar bushes etc), the side gears take up the clearance, and the
"U " joints or cv joints take any wear
Best advice is--- if all you have is a clunk ( check everything outside the diff first) and the diff runs quiet under acceleration or deceleration, DON'T fix what ain't broken
I would tend to believe it's more likely a worn sway bar bushing or link if it's a rattle or a small clunk, if it's a loud clunk probably a strut, try bouncing he back of the car when parked, if you get the clunk probably a strut if only when driving,turning,braking probably just a bushing on the sway bar
not enough info for diagnosis, Try putting bar soap and check tension of fanbelts for squeaking noise of the belts as a cause. The clunk maybe worn or damaged suspension components, cv joints or even worn or broken motor mounts. Start with these items...
The humming noise could be a wheel bearing, as for the clunking noise does it relate to the brakes at all? If it is with the brakes could be caliper/pad clip maybe the problem. If not brake related possibly it could be a motor mount.
Had similar problem with 2003 Dodge GC. Replaced the parts you mention + rack & pinion, then to fix the now noticable whining noise, replaced power steering pump and pulley. Fortunately was under an extended warrentee at 46k miles.
