After much searching, on the web and local suppliers, and help from members, particularly Steve Green, I think I have finally sorted my drive-train and made it quiet!!
The gearbox replacement part were sourced from T D Fitchett (Telford) who have Marina parts on their 'back shelves'; also a couple of weeks back they had just received a 'new' supply of Marina diff components.
My repairs were carried out by Steve Ellis - a family run business in Westbury: Ellis & Dunn Gearbox Solutions. I can thoroughly recommend him if members are in this area.
And now to continue the tinkering ...... between these balmy evening drives .....
- As I posted previously the gearbox was repaired giving me a reverse gear and making it 'tight'.
- The diff has also been repaired. Any noise emanating from it was due to shredded shims and misalignment. As I suspected from initial inspection there was negligible wear, at worst, on either the crown or pinion.
- Put in EP85w-140 oil, more akin to the van axle than EP90
- But the 'grating' was still present particularly between acceleration and over-run.
- On further inspection I found that there was lateral movement in the front universal joint of the prop shaft. This I concluded was due to smaller width than usual on two of the cir-clips holding the caps in place! (There were two distinct pairs of clips rather than a set of four.)
- A new universal joint later and all seems well = a different driving experience!
