Do you mean the diff itself is hard to spin or the spider gears inside? What weight diff oil are you using.

Are you sure its shimmed properly? Uneven shimming will bind up on you

Sorry I meant grease I'm not sure the weight but its the same as the diff grease that's on tie ring gear but Ik its not the shimming cause there's still a tiny bit of play they were fine before until now and I think its in the spider gears somewhere. The output cup is hitting the metal rod the spider gears go on(sry don't know name) on the inside of the diff

Did you by chance leave out the gasket? I have done this before and it caused the same problem.

It actually was the gasket it was hitting the gears inside because it was torn up so I got a new one. But is there anything else I could use to keep a seal on the diff besides the foam or whatever type of material gasket they give u?

I guess you could make your own rubber seal. I have never had issues with hpi's gaskets leaking. It's a good idea though to replace the gaskets every time you open up the diff.
