I had a 68 loaf in Alaska - had the CV's greased, and later at some point in time was cruising down the road when I started getting a popping noise in the rear and before I could get slowed and stopped all hell broke loose. There was a heck of a banging in the right rear. Not much warning. When I got stopped, I looked underneath and found all the bolts out and the axle hanging down on the right side. I flagged a car, got a lift and ultimately got the thing back running again.

After that episode I determined I was not going to have bolts come loose again, so I drilled crossways across the bolt heads and after the bolts were installed, I strung a piece of stainless steel aircraft safety wire through those holes, so that the wire was aligned in accordance with aircraft maintenance safety protocols and the bolts were pulled by the wire in a tightening direction. I was determined those bolts would never come loose again - and they didn't. Years later, with my 85 GL I encountered the same problem. And I applied the same fix - at least on the tranny stub axle flange end of the axle. But i found that the newer van had a box construction swing arm where the outboard stub axle flange was buried in the swing arm box. Pretty awkward to safety wire the bolts there, so i subbed a bit of Locktite on the bolt threads. That seems to have worked. Never again had any trouble.

Just some tales of CV woes. Take it for what it's worth.

John Rodgers 88 GL Driver
