I just got done replacing the pivot seals and re-sealing the bi-speed box. I started it up today for the first time, put it in drive and I feel a bind coming from the front end. The front wheels would just lock up. Just to double check, I jacked the rear up and gave it throttle, rear wheels spun fine. I don't know whats wrong with it. I did all of my testing in 2WD. I don't dare want to try putting it in 4WD to see what happens. I don't know how this could be messed up because before I sealed everything up, I spun every thing by hand and it all turned freely. I had bi-speed turned off when I did this, well at least I think I did. How much of a range of movement should the linkage arm for bi-speed move? It doesn't appear to move a whole lot but it feels and looks normal. I feel somehow where the driveshaft connects to the axle is bound up. Also, I replaced the roller shaft assembly and the new part was smaller but my dealer told me thats how it should be since its and updated design. Any advice?
