I was wondering if I can safely use stock drive shafts on my '84 4runner with no lift and a flat belly? I had to pull the rear because of a bad u-joint and it seemed like it had plenty of spline left, but I am wondering about the joint angles. Will the joints be fine or should I shim the rear axle? I drove it about 6 inches in the garage on the front shaft and it worked, but that is far from real world. The pinion seems to point up quite a bit, plus it has a double cardian (sp?) joint on the t-case side, but I have never pulled the shaft so I have no clue how long it actually is. Oh, I only raised the rear end, didn't mess with the front engine mounts if that helps any. Thank you for your help.
