replacing drums
 

so i'm replacing the internal drum hardware as needed on my xj, but does anyone recommend replacing the housing/assembly? Is there any reason to or am I just over complicating things.

Are you speaking of the backing plate that attaches to the axle upon which all of the hardware is attached?

No I am talking about this

Just like a rotor, they have a minimum thickness that when reached they should be replaced (I don't know the number off the top of my head. They also are advisable to replace if the braking surface is significantly grooved, pitted, or if the drum is warped, internally tapered, unbalanced, or has run-out (is out of round in some way).

They don't wear out easily, and you probably do not need to replace them, but only you would know after having inspected them.

That is the brake "drum". If the shoes have worn in so there is a lip left on the outer edge, takem both in to be checked-turned. Regular "box" auto parts usually have a lathe in back, or can tell you where to go.

Just wanted to add to Jordans info. The drum will have a "max dia" spec cast on the outside. The drum can be turned smooth and round on a lathe and used if it's under the max diameter.

Comparing your cost for that, with your cost for a new one is a thought.

Thanks for the help guys !

Here is a tip.

Replace one side at a time. If you are unsure of how it goes back together just look at the other side.
