redtin 0 #1 Posted July 2, 2011 Hi Horsemen Any idea if there should be washers under the four diff bolts on a old C series box I have just boxed up and then thought oops should there have been, as it just had the locking nuts and looked as if it had never been down before I only have numbers on the box so unable to identify it's 1 1/8 axle Thanks for any reply Dan Share this post Link to post Share on other sites
daveoman1966 3,762 #2 Posted July 2, 2011 Schematics show a flat washer under the head of the bolt, but not on the nut end. You should also use Blue Loctite on threads / nuts...even with the nylok nuts. I've seen these separate before. I've also opened virgin diff cases with blue Loctite on threads. Just wipe off excess.
