Hi, a couple of things
firstly you need the diff flange and g/box to be slightly out of line either lateraly or horizontaly if you have them dead in line your u/j's will suffer from brineling an thats bad
secondly you donot have to put your pics on the web to put them on here
its quite simple to add them by uploading from your computer
heres how
theres a box below the message box its called additional options
click manage attachments then a new window will open
theres a box next for upload from your computer click browse find your pic on your computer select it then click upload it should upload to the site if not youll get a message telling you why e.g. file too large so you may have to adjust size or whatever anyway give it a go
hope this helps
Ray:)

Nice one Ray,

I like learning something new, however 97.7KB for a JPEG is small. I would have to reduce pictures especially for the forum so might as well stick them on photobucket. Maybe if a take a photo with my phone. Good tip though

Thanks for the info Ray.

The way things ended up I had to drop the end of the gearbox anyway to make the engine fit better under the bonnet. With the alignment now I also think I should be able to use the rubber coupling at the front like Westfield do and with a bit of luck that will reduce the shock loading on both the gearbox and diff.

With regard to brineling, the Sierra has everything pretty much in line, and you're right - when I checked the rear UJ on my donor it had obviously worn heavily in one position. Hopefully it won't affect me too much with the mileage I'm likely to be doing.
