Rear brakes sticking?

Get your rear end in the air and pull your drums and show us what you see.

I would think it's likely the thud is unrelated and part of the drivetrain or axle wrap, especially considering it sounds like from what you said the brakes are staying dragging not just sticking then disengaging once started moving. Have you ever greased the slip yoke? Very common on these, mine was pretty dry at 150k. Quick, easy and cheap can't hurt to do it.

 

no, but i don't see how the slip yoke is going to effect the brakes dragging. my front brake pads do make a clacking noise when switching from reverse to drive or drive to reverse. i'm guessing they are just shifting around the caliper. need to grease those up too. my main issue is the brakes dragging.

 

What I'm trying to say is your thud/clack/whatever noises when unloading and loading the drivetrain in different directions may not be from your brake pads. But if you're convinced that's the only problem/cause then just fix your brakes haha

 

Probably a sticking cable. My left rear cable got a cut in the sheathing from the bracket on the leaf springs, dirt and water got in there and it would freeze up in the snow. I would un-stick it by grabbing the cable and pulling on it and flexing it around

 

ok, does a slip yoke cause the brakes to drag? does it slow down the truck? does it cause the drums to overheat?

 

No, those are two separate issues with similar but different symptoms. For the brakes issue take it apart, lightly lube the shoe to backing plate contact points and properly adjust the brakes while they're cold. While doing that inspect for a stuck cable to the drum and cable sheathing for damage, if you see rust on the cable(s) going into sheathing or damaged sheathing(s) replace the cables. If nothing found brakes may have become over adjusted

 

good advice. i know they disconnected my rear brakes lines when replacing my rear diff under warranty recently. I'm wondering if they didn't bleed them or didn't bleed them properly.

 

I'd more so investigate for a pinched cable/line knowing that, also why not return to them to sort this out if it happened following the repair?

 

Seen some of you were asking about the "axle wrap" nonsense. I have a 2006 and live in Canada. Corrosion caused a leak in the transmission cooler line. Eventually enough fluid was lost that the transmission could no longer downshift when stopping. Shortly after coming to a stop, enough pressure would build to shift the engine. That is what caused the jump forward and ever since I drained/refilled my fluid to the proper level, it NEVER happened again.

As far as the brake sticking issue goes, I've dealt with it too. You likely have some dirt in the hose that the parking brake cable runs thru.
