Bravo 3 UJ's - Play

Trying to help a friend out.


I have a very vague description of an error "making a dodgy sound when on full lock either side" - He didn't give me a chance to have a listen and now the out-drive is off.


To me, it sounded like the Gimbal (from his description), but it is smooth and when I turn it by hand it's smooth (but would you know by turning it by hand?) - Also appears (to the ***** eye) ok aligned but I appreciate this is not scientific.


However, one thing I noticed is that there is some play in the UJ's. On one of the cross-bars (is that correct?) there's about 1mm, on the other much more, possibly up to 2mm.


I'm taking that this is not normal? Should there be *any* play?


Many thanks for any info you guru's can provide!

Thanks for the quick response. It's only when I looked at it in day-light it's obvious there's an issue there!

I also noticed some gear-oil in the bellows (maybe 5ml) - could have been there from before, but i'll be telling him to sort out the out-drive seal up there, too.

What I also find suspicious is that when I turn the UJ, there appears to be also play on the pinions on top of the out-drive. We haven't lifted the top cover of the out-drive, but this is what it feels like: https://www.youtube.com/watch?v=LjFXW3fIODA

From the video and assembling Bravos that a bit too much play in the gears. Than can caused improper install of the input shaft or its bearings, The oil in the bellow may be from a leaking carrier seal on the input shaft.
