My rearend went out in my Tahoe. So I bought a used one from a guy. I got mine apart and when I tried to install the new one I discovered the bearings are bigger and it won't fit. Does anyone know if I can get bearings that will fit in my race but has a larger diameter inside the bearing? The guy I bought this one from won't give Me my money back so I want to know if there's any way I can still use it. Any help will be appreciated
