Had a strange vibration at about twenty mph in the Ford Maverick. Ummed and ahred and decided that a U/J had seized. (Split propshaft with C/V joint at front, centre bearing and U/J and another U/J at the rear diff.)
Sure enough, the centre U/J was solid! Fortunately Yankee engineers usually use clamps to hold one pair of spiders in place so not too hard to split the prop-shaft, although the C/V out of the transfer box was a bit of a struggle.
What a bastard trying to get the old u/J off the prop!!! I have never, ever had one where the bearing case was rusted solid to the spider. It was so bad that I had to cut the needle roller case off first.
Now, a real miracle! I looked in my new spares box and there, was a brand new, still in it's box, Land Rover U/J and miracle of miracles it was the right size AND it had a grease nipple! Utterley amazing.
All ready to put back together and instead of being scrapped it's back on the road in all it's V6 splendour. I love Yankee trucks.
