Got my 4R back on the road after a rear axle seal saga. New bearings, seals, diff breather, shoes, brake springs, drums turned. 6 cans of break cleaner to clean the gear oil. But now it makes a god awful scraping soundcwhen i drive, i think the backing plate got bent slightly and rubbing on the drum. I'll fix it tomorrow and do the front rotors and pads too. I got a mityvac bleeder but it didnt work very well, air gets in through the bleed fitting threads and makes a stream of bubbles.
I spent about an hour trying to decide how to route the diff breather extension so it would have enough to flex, but not kink or have low spots, and not rub against stuff or interfere with anything else.
