jack it up,put on jack stands at the frame
run the t-bar adjuster down to release the tension on the t-bar
remove the clips at the end of the bar in the cross member
mark the bar for referance so it clocked the same way when you re-install it..
slid the bar out toward the back of car,it will come out of the lca pivot
grease up both ends of the bar and re-install it
you might want to spray some kinda of oil on all the rubber bushing while your at it,they will dry out and squeek also
I have had ball joints do the same so lube it up
if you adjuster bolt is all the way off the bell crank it should come right out...but...
some times they can be a little hard,so use a shop rag and wrap it up good and use a set of vise grips to clamp on the bar..now hit it with a hammer to drive the bar back some then out
they make a t-bar removal tool and can be made up with some scarp and thinking..all it needs to do is clamp it with out nicking the metal bar
good luck and be safe with the jack stands,chock the wheels in back and set the brake
