Earle BryantVerified owneron MST CMX Front motor kit

While I’m so thrilled MST has provided a CMX conversion kit… I’m a bit disappointed with the fact that they had the incorrect bearings in the kit so I can not complete my assembly. After coming to the transfer case portal of the build, I noticed two incorrect bearing sizes that kept me from finishing the T-case. I figured maybe I installed them in the transmission by mistake, so I took everything apart and studied everything carefully. Only to find out two bearings have the incorrect inside diameter to fit over the idle shafts in the transfer case. Outside diameter is correct, inside is not. I’m currently waiting on bearings I have to buy to finish.
