Hello Everyone. I am still plugging away at this 94 Cruiser. I have replaced so many parts on this thing It's ridiculous. Short Verison....Something went bad with the front axle. It had impact to the front right of the vehicle. I had the frame measured and thank goodness it is striaght. The Alignment shop thought that it might be a bent mount on the differential housing . Also had a bad U-joint on the Front Driveshaft. Rather than try to rebuild the front axle or the Birfield, I found a set of Locking axles on Ebay. I am most of the way through the front axle Swap. I do not have any switches or computer for the front or rear. My question is can I drive on the front axle prior to swapping the rear and prior to installing ecu and switches. From what I understand there are a couple of gear ratios. So if my rear ratio is different from the Front, I will probably have problems. Is is safe to test it on grass, gravel? How will I know if the gear ratios are different? Thank you.
