I have two early 1980 land cruisers up on blocks for several years. Want to take them off the blocks to toe them to a new location. Was checking that the rear wheels on the cruisers rotate easily before I take them off the blocks. I find that the rear wheels on one rotates freely without the rear drive shaft rotating while the other cruiser rotates with some difficulty with its rear drive shaft rotating. Maybe if i could disengage the drive shaft from the rear wheels it would free wheel more easily. I would appreciate advice please on how I can disengage the rear driveshaft rotation from the rear wheel rotation. The gear shift lever in both cruisers is in neutral. Maybe its something simple, but I just dont know how. Please advise, thanks.
