On my 79 FJ40, when i take it out of 2wd now, the front drive shaft doesn't fully disengage. It grabs every other rotation like and makes a terrible clunking where it isn't catching. If i put it in 4wd, it doesn't make any noise and acts right. I am wondering if there is a way to adjust/replace the sleeve or if it may be something in the shifter? Any help would be amazing, driving around in 4wd around town isn't too fun with no power steering
