i recently bought a used drivshaft for my75 dodge b300 from a junk yard, drove for a week or so no problem then i noticed a fluid leak and found my extension housing bushing had walked its way up the yoke as did my seal, this bushing was about 3 inches or so out of the trans,, so next step is removing the extension housing to inspect for damage but i cant get it out ,, got it loose it moved back bout an 1/8 inch and will move left and right a lil bit but wont pull straight out...................... what am i missing?is there a snap ring or something i need to remove ????,,, i dont see whats holding it back , please respond ,,,
