I was able to fix the inner tie rod problem with a little of patients and 90 bucks for the parts. When I took it in for the front end to be aligned the drivers side was only off by 1/4 on an inch.

That was a good suggestion by Molson. Also, if you have been doing a lot of heavy hauling, have them check the strainer, which could be a problem as well.

This is for the front: Removal & Installation

1. Remove 2/3 of the brake fluid from the master cylinder.
   
2. Remove or disconnect the following:
   
   • Wheel
     
   • Caliper. Suspend the caliper from the frame with mechanic's wire. Do not allow the caliper to hang from the brake hose.
     
   • Caliper mounting bracket bolts
     
   • Caliper mounting bracket from the steering knuckle assembly
     
   • Brake pads from the caliper mounting bracket
     
   • Clips from the inside ends of the caliper mounting bracket and discard
     

1. Install or connect the following:
   
   • Clips to the inside ends of the caliper mounting bracket
     
   • Brake pads to the caliper mounting bracket
     
   • Inner pad (1 wear indicator)
     
   • Outer pad (2 wear indicators)
     
   • Caliper mounting bracket to the steering knuckle assembly
     
2. Perform the following procedure before installing the caliper mounting bracket bolts:
   
   • Remove all traces of the original adhesive patch.
     
   • Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.
     
   • Apply red Loctite®272 to the threads of the bolt.
     
3. Install or connect the following:
   
   • Caliper mounting bracket bolts to the steering knuckle. Tighten the caliper guide pin bolts to 74 ft. lbs. (100 Nm) on 15 series or 80 ft. lbs. (108 Nm) on 25/35 series.
     
   • Caliper
     
   • Tire and wheel assembly
     
4. Refill the master cylinder to the proper level with fresh brake fluid. Pump the brake pedal slowly and firmly in order to seat the brake pads. Burnish the brakes as needed.

Normally the engine operates at 195F, if you did not replaced thermostat with another one at 185F. If the temperature has a tendency to rise up, the reason is a partially obstructed cooling system or/and a bad thermostat.
The first part of the cooling system that gives up is the heater core, because the coolant flowing channels are thin. You got a good advice but not the best one. It is the time for a coolant flush in your car. To do do it right then you need time. Plan ahead for a week end. With a cooled engine, start as your friend advised you with the heater core hoses. Disconnect both of them, but the dirt has to go out of your car, so with a garden hose back flush it and let the dirt to get out of your cooling system. After you will get clean discharge, it is the time for coolant bottle, remove it, discharge the used coolant and clean it. The third to come is the radiator. Open the drain cook, or disconnect the lower radiator hose, and disposal used coolant properly. Now open the radiator cap and flush with water the radiator till discharge will be clear. You think that you are done? Not yet. There is half of old dirty coolant trapped in the system.
Install everything, and connect all coolant system hoses, radiator, heater core and coolant bottle. Now you have to run your car with water. Fill out the cooling system with distilled water, start engine, turn on the heater high, and run till upper radiator hose get hot. That means the thermostat opens.
Let the engine to cool down, open the radiator cap, and draining cook or lover radiator hose and drain everything. You can use flush detergent if you wanted at this stage, but flushing with detergent will add 4 more hours, because detergent is colorless and you have to guess how many fill and drain processes do do to get rid of it. I do not do it, but if your cooling system is very dirty you have to do it. After the last drain, fill the cooling system with concentrated antifreeze and 30% distilled water. The reason is because it is more water trapped inside the cooling system. The goal is to reach 50/50 concentration. You need a coolant tester to find this. Start the engine and add coolant til radiator is full. Install the radiator cap and bleed the system. After driving you car for a day or so, let engine to cool down, open the radiator cap check the concentration of coolant with the tester and add antifreeze or distilled water as necessary. It is a good idea to replace the thermostat while flushing the radiator. This procedure has to be done every 2 to 3 years. It is up to you to decide to use RED GM Dex-Cool or GREEN Prestone antifreeze.
In all my cars I have replaced Dex-Cool with Prestone, but I flush the system every 2 years, and I never had a cooling system problem in all my cars.
