Rolls forward in neutral, locks up rolling backwards??

Sorry I took so long to get back on here. The band only has one end that the strut fits. Did you air check the drums mounted onto the pump with it chucked into a vise? I air check every drum twice; once before I take out the piston to find out what happened and then again after it's reassembled.

Thanks, I was going to air check the apply levers but didn't know to air check the drums. Luckily Nothing is assembled yet, so I can still do that.

Dont know if that rearend has adjusters for axles on it like the 8 3/4. But had the same thing happen on my race truck. The clip that holds the adjuster from moving bent, and everytime I rolled it backward it would tighten up and bind the axles. Felt like what you are saying. Worth checking. I almost jumped into my tranny aswell

Thanks for the input! I'm pretty sure I found the problem in a previous post; the drums fell out of alignment when I pulled the pump for an unrelated issue. I didn't tighten the front band before pulling the pump, so everything fell loose. Post 53 shows the tangs of the front and rear drums misaligned, I'm pretty sure that's where I screwed up.
