Q: The upper rear shock mounting
keeps coming loose on my 1960 300. I retighten but it comes loose
after a few hundred miles.
|
|
A: A common problem on 1960-64
unibody cars. Remove plug in trunk and remove nut. After shock is
removed, remove the shaft and install a tight fitting (I.D.) thick
washer over the shaft. Install shaft so that the washer is on
underside of body. Reinstall the shaft, tighten nut in trunk and
reinstall shock.

|
Q: My 1961 driver’s seat is
very “lazy” when pivoting out. Any help?
|
|
A: First, check the spring
tension. If weak, replace it (a hardware store item). Remove seat,
clean Nylon rollers and track, lube with lithium grease. If Nylon
washer is missing on top of frame for pivot bolt, or worn, replace
(a hardware store item) and lightly lube.

|
Q: I am getting many different
answers as to what lube to use in my 4 speed A833 transmission.
What is correct?
|
|
A: Chrysler service
bulletins designate “automatic transmission fluid.”
This fluid should be type F or FA. This fluid should also be used
in all cast-iron 727 and 904 transmissions. Do not
use Type A Suffix A, or any Dextron or Mercon.

|
Q: I installed heavy-duty turn
signal bulbs and my turn signals flash very rapidly. What’s
wrong?
|
|
A: You must use a heavy-duty
flasher unit to get proper turn signal flashing. Since more
current is used to flash heavy-duty bulbs, the flasher has more
resistance, hence, slower flashing. Heavy-duty flashers are
available at all parts stores.
|
|
Q: My steering wheel always wants
to turn slightly to the right on start up. Why?
|
|
A: The control valve on top of the
gearbox is out of adjustment. Loosen the two bolts and readjust
without engine running until you find the correct position, and
restart car until corrected.
|
|
Q: When I put the transmission
into gear there is a “clunk” sound from the rear end.
Also a “clunk” going from drive to reverse and
visa-versa when the car is at idle.
|
|
A: That “clunk” is in
reference to excessive rear axle clearance. For both standard and
Sure Grip, axle end play should be .015 to .020 for each axle.
|
|
Q: Driving on the road during down
shifting or up shifting, it sounds like the transmission is
hitting something.
|
|
A: It may well be. The
transmission insulator (mount) may have separated and allows the
transmission to “jump” up and down on the cross member
and also hit the tunnel in the floor. A left front engine
insulator (mount) could cause this if it has failed.
|
|
Q: Can a stock tachometer from a
1960 fit into a ’63 or ’64 300? Or visa-versa?
|
|
A: Yes, but a 60-61-62 tach must
have a 200 volt supply to illuminate the face and needle. (A 60-62
power pack is required). A 63-64 tach can be used in 60-62 cars
but needs a hookup for a light bulb to illuminate the face and
needle. The cable is the same for all years with a mechanical
tach.
