After I had my 52 for a couple of months the u-joint went out. After I replaced the u-joint I lubed with 90 weight gear lube via the square plug in the rear of the tranny. A pint is good, a quart is better mentality prevailed. After filling the tranny, I decided to check the rear end, and gear lube poured out. So note to self follow the manual. Ya don't need more than a cup or so to lube u-joimt. Jimmie.
