Re: 1992 U300 turn signal / cruise control lever replacement suggestions needed

(speaking from hazy memory here)
The fixed metal turn signal lever is a simple straight rod, roughly 3" long and 3/16" diameter. Has a hole that receives a roll pin, which locks the plastic cruise control assembly in place, after it slides on the metal rod.
The metal rod does not extend far enough into the plastic cruise control assembly, resulting in a very weak joint. Kind of like a knife where the tang of the blade is very short, making for a weak connection between blade and handle. When you put pressure on the turn signal lever all the force is concentrated right where the securing pin is located, resulting in a tendency for the plastic to fracture at that point.
The repair process entails filling the inside of the hollow cruise control body (in the area where it mounts on the metal rod) with J-B Weld and then sticking it back on the rod to set up and cure. I also reinstalled the roll pin in mine to help strengthen the connection. Once the epoxy cures, the assembly is significantly more robust. Although, like nitehawk, I also make a practice of gripping the stalk close to the steering column when activating the turn signals and high beams. This hopefully reduces the strain on the repaired joint. My repair has held up just fine for 8+ years (knock on wood).
