I have two issues 1) I have a click/clunk in the steering mainly when I make a left turn is this the steering column or something worse and 2) my speedometer works only part of the time ex I could be driving it is at the correct speed then all of sudden is is stuck on zero????

there are probably small plastic lock pins that take up the slack in the column
these break of when a heavy pressure is applied to the wheel either by the drive or in an accident to allow the column to collapse
the fix is a new steering column
check the steering column for failed "U" joints or flexible connections
Take it to an accredited specialist steering shop for a proper diagnosis

check for loose steering box / rack. Check all steering ball joints and suspension joints. have a steering specialist shop check it out as steering problems border on safety

this might help:
Here is the Technical Service Bulletin that maybe of help, worth looking into but can't guarantee that it would fix your problem Steering - Steering Column Clunking When Turning TECHNICAL Bulletin No.: 01-02-32-001P Date: November 25, 2009 Subject: Clunk Felt/Noise Heard From Steering Column, Steering Gear and/or Front Of Vehicle During Turning Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft As Directed) Models: 2001-2004 Buick Regal 2005-2008 Buick Allure (Canada Only), LaCrosse 2000-2008 Chevrolet Impala 2000-2007 Chevrolet Monte Carlo 1998-2002 Oldsmobile Intrigue 2004-2007 Pontiac Grand Prix Supercede: This bulletin is being revised to add the 2008 Buick LaCrosse/Allure. Please discard Corporate Bulletin Number 01-02-32-001O (Section 02 - Steering). Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver.
1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle. 2. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. 3. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. 4. Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk/noise condition. 5. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction. Correction DO THIS - Replace the intermediate shaft DON'T DO THIS - DO NOT lube the intermediate shaft Replace the existing intermediate shaft

your clunking is probably caused by a bad steering u-joint or knuckle at the bottom of the steering column.(at rack and column)

I have had that problem with my wifes car,i called a mobile repair guy to come out and tighten something in the steering column,cost me about $50

sounds like a rack and pinion issue or your steering column joint and or bearings are spent. Call a chrysler/dodge dealership, ask for service and see if someone is nice enough to list off some possible causes to your steering column sounds

there was a service bulletin for a steering column clunking, but a clicking might be due to a torn cv boot located on your drive axles. If it is the cv boot then there is sometimes grease that leaks onto your front rims if enough gease leaks.

The probably lubed the intermediat shaft conenction. The loud poping noise could be from them not sitting the boot back correctly. Inspect your boot. As for the moaning noise Only thing I can think of is a hydraulic noise.

The clunk as you describe could be one of three problems, the steering lower column, the steering gearbox or the constan velocity joints.
The lower steering coloumn viewable from the engine bay below the brake unit has a rubber coupler which breaks and can cause the column to lock up, the steering gearbox which the column mounts to can also fail inside, fiunally the c.v. joints break and will cause intermittant binding of the steering, you need to goto a car park and drive the vehicle full lock left and right and have someone listen for the clunk, if it is coming from the wheel area then its the cv joints.
I would start there, hope this helps
