I really appreciate your attempt to help, but as you recall from many
previous posts, pinging is a problem cured by higher octane fuel. I run 89
octane and the only time my Dak pinged is towing my trailer in hot weather
up hill. I added a bit of 'high test' and that cured the problem. I'm sure
if a 180 thermostat was the cure, Chrysler would put them in the truck from
the factory. My 89 Sundance pings unless it gets 92 octane and it was
just tuned (plugs, rotor, cap, wires, scoped etc.). I suspect as well as
load and temperature, the changing formulation of gasoline from summer to
winter also affects it. My 78 1/2 ton, my 78 3/4 ton and my 77 Plymouth
Volare all pinged on regular gas. They all ran fine on higher octane fuel.
There were all SUPPOSED to run on regular gas.

Thanks for your suggestion, but as I indicated in my post, my dealer
serviced the E brake
and beveled the brake shoes under warranty. He also checked that the brake
was operating as it should in his shop. The cables are free. I'm sure the
mechanic has read the repair manual :)
Sometimes someone on this list (remember the intermediate shaft and mirror
wind whistle) has had the same problem and knows the exact cure. This is
helpful, particularly if my dealer hasn't had the problem before.
