Hello, we have a 2130 JD that, while driving, started leaking a large amount of oil out the top. We watched Bundy Bears Shed video which was very informative. If anyone has done this job on the tractor we are at the stage where the big nut is loosened but we can't turn the steering wheel any further than its normal limit to get it to release. Anyone run into this? Would appreciate any advice. Thx
