I have a 8 3/4 sure grip that came out of a 74 pick up, it feels like there is something stuck in it. It will only spin part of the way around, can these be rebuilt or is it junk?
if its a bind in the gearset you should be ok...but the cone type sure-grip is a non-rebuildable unit, although you can take it apart if there is some other trash stuck in it.
You can rebiuld the cone type. I cant find the article now but you just need to machine the outer face of the cone I believe.035. I think it was in high performance mopar mag a few years bck.
