Thanks BigCol, I have the instructions from ScottR400D which are very helpful. I think i should be ok now, but I’ll be sure to ask if I get stuck!
I have the diff out and will speak with SPD and arrange a visit early next week for fault diagnosis and replacement. I’ve ordered the replacement bolts etc from CC, apart from the nylon spacers as they are out of stock, has anyone found an alternative source for these?
What has happened with all the faulty Titan diffs? Has anyone found a market for these?
Thanks to everyone for all their assistance and advice, it’s much appreciated.
