05 250 recon help!!

New here and this is an amazing site to find info but can’t find this. I have an 05 recon that a buddy let me work on. Needed new valve guide and had a bent valve. Well the rear end is also locked even in nuetral. When we pushed it into his garage 6 months ago it rolled just fine. Already pulled rear breaks off and didn’t help. Any info is appreciated! Thanks!
