Hi, first post here. I would appreciate some guidance before I tear into this thing too much. I have a late 90s max IV that has had a gradually worsening issue where the left stick requires more and more effort to operate and finally it has gotten to the point where I just can't steer the vehicle (not to the left at least). The gear shift seems to work OK and the right stick operates pretty well. Is a T20 rebuild in order? What is the specific issue that causes this? Thanks in advance for your help, I've found this forum to be really informative.
