Ok I have a 96 ranger 5spd. The little plastic piece on top of the gear shift nob that tells you the shift pattern is loose and is making a very loud noise. Its so loud that when I first heard the noise I thought for sure something was loose behind the dash. I finally narrowed the noise down to the gear shift nob. Well the bad part is the the entire nob is not secured to the shaft securely because of the thread patter on the shaft not the nob is broken off. So my question is can i somehow replace the nob? or do I have to replace the whole shaft? Or any other way? Thanks in advance!
