Here's a challenge ! If you don't know how to do it right, you'll
spend a lot of time (and experience hair loss), break some tools or, worse,
break some parts (drum, studs, etc..) There's indeed a "trick" or rather a
DO NOT : use a classic
3 jaws puller
and put the jaws on the edge of the drum: you will
Why ? The rear drums of the mopar have a
"drum-hub" assembly. The wheel studs or bolts are crimped
into this assembly. The drum also is riveted to the hub so you must
remove the whole thing, hub AND drum. Another problem is that the hub
has a conical (tapered) slip-fit which is an excellent fit but also the
hardest to remove. Note that the cone is 2 " long and, perhaps the drum
hasn't been removed for years ...
to ? You must find the "right tool": a special puller which was
used in the '50s-'60s on Mopar but also on other brands (Packard). It seems
that Napa or other aftermarkets store have it but beware, you must buy (or
rent) the strongest you find. Look also at
come up for sale at times. Note that I've made the one you see on pictures
for me and my Mopar's friends
You must be
patient and strong ....
Loosen the axle nut (2
or 3 turns) but DON'T REMOVE IT, it's a safety factor !
Install the puller on
the studs or bolts
Tighten the puller with
a long extension or with a hammer, depending which puller you have.
Take a big hammer and
heavily strike several times the end of the puller (mine was made for
Repeat 3 and 4, take a
pause, a beer, a cigarette etc..
After several 3-4 tries
you'll hear an explosion with some smoke (brake dust), the puller will
be loose. You've won ! The drum now rests on the axle nut.
Remove the nut and pull the drum (don't loose the axle key). Without
the axle nut the drum-puller assy. would be thrown through the space
(or your legs..).
In desperation : sometimes you'll
spend several hours before the drum pops off so don't worry, after a while,
repeat 3 and 4 steps.
You can also heat the hub
near the axle. But don't heat the axle itself
Another trick (but the car
must be driveable): do the # 1 step then drive the car 1 or 2 miles (with
some curves but not at high speed..). Then follows the 2-3- ... steps
look at the inside of the hub and drum assy.
Other infos from
mailing lists after i posted the URL of this page:
Remember to release (Back off) the
adjustment of the brakes before removal of the drum. Sometimes, if badly
worn, there is an interference between the drums and the shoes. (Joe)
I think that this method would also
apply to drum removal prior to 1957. Maybe someone with a '30s model can
confirm. I am sure that '40s Chryslers were the same. I know that my '55
and '56 also require the same method. (Paul)
During the holidays I posted a request
for info re: finding the proper puller for my 58 DeSoto. Several members
JC Whitney puller for $28.99 ... I bought it and it worked great, and
it is a great price, as well! (Bryan)
To whom it may concern i recently went
to the local Auto Zone near me and bought a 20 dollar puller that worked
perfect on the 60 Plymouth i recently bought.They also told me i could
return it for a refund if i didn not want to keep it.. Needless to say it
fit over the hub the studs and all so i kept it. (Jack)
(...) By the way...another reason for
leaving the axle nut in place: when tightening the center screw, the axle
end is often damaged, causing problems with the threads for the nut. By
leaving the axle nut loose, when the drum pops loose and the nut is
removed,the threads are nicely restored . (Mike)
I use an impact wrench, the one that
looks like a gun. This seems much better than a hammer, and always works
well. Also: put grease on the threads of the center part so that when you
are spinning the center with a hammer, it goes easier!!! There
should be NO oil or grease put onto the spindle before you re-assemble.
If there is lubricant, the woodruff key (square metal rod on axle) will be
broken off by the car's power after time. Re-assemble DRY.
