Steer tire fighting turns, delayed reaction. Why?

Hi.
Thank you you all for your insight and advice.
Before I get put on blast for bad maintaince I just want to air my side. I do have a greese gun. But when I dug it out of the barn and filled it. I didn't know there is a difference between a tubed and tubeless greese guns. So my tubeless greese gun now has a tube in it preventing greese from flowing. What I have been doing is scraping the greese out smearing it on the fifth wheel. And I'd hope to do this Untill the tube was empty.
I didn't worry much about the 4 or 5 greese fittings. Under the truck as they where just greesedd about 2 weeks ago..
The big however comes into play. When I had left last week I did not greese the fifth wheel, and it was about 75,300 on the cat scale. I was running behind and figured I could buy the bags on the road.
I have since bought 4 and used two. What a world of a difference. I new the fifth wheel had to be greesed. But I didn't know what a non slick fifth wheel would do. As soon as I read that comment I new I messed up.
My plan for the greese gun is to get home next week and just pull out all the greese. So I have the gun with me. Even tough there is a tube in it, I put some greese in the top of the gun and use it under the truck. I hadn't since the oil change several weeks back. I will now be doing this on a semi weekly basis. For the first time in my five years out here, I was nervous do to something mechanical and not something mother nature conjured up. It was scary turning left but still going straight. Thanks to every one who repield and helped.
On the flip side I know have new brakes all the way around, new drives. And will have new steers and alignment this up coming week. Wish I would have shopped around thou. What would be a decent steer tire for decent money. I just replaced the drives with what was on there. After it was all said and done. The man said you could have saved 250- 300 atire had I gone with yoko instead of Michelin.

 

Can I just replace this rubber, or is it a whole bar replacement job?

 

I will check both firestone and Hancock. Thank you.
Checking the torque bar on you tube and Google it looks to be a easy yet time consuming project. I'm gonna call new England truck center and them to price the part monday.

 

No worries on understanding the way I talk. Only my mother and my wife get it most of the time. When I type it comes out more clear. Untill I get in a hurry. Between a mind that won't sit still and auto correct. It may take me 15 mins to type a 3 sentence response. You've helped before and I'm sure you will again. Thank you.

 

For future reference what causes that bushing to slide or the torque rod to slide off the bushing?
