    • If looking for new trunnion bushes, pay attention to the seal and shields supplied. if they supply round section o-rings or one of the shields is a washer, return them. These are what the bad ones look like: https://www.ebay.co.uk/itm/175401880706 Last time I fitted them they were too wide, so I had to spread the vertical link to fit them, and then if you tighten the trunnion bolt more than finger tight, they seize. Possible they've improved, but when I complained about them I was told nobody else had a problem...  
    • My father’s father also. He did go to Italy afterwards. He didn’t talk about it.
    • Saw this old beast today (and it’s keepers 🙂) Unusually tidy example and seems to go ok too.
    • I agree that the backlash looks fairly typical -  I’ve seen worse. Almost certainly most of that will be in the differential gears due to worn thrust washers rather than the CWP. I definitely wouldn’t mess with the pinion nut unless there’s obviously float in the bearing. The clicking could still be a driveshaft UJ, even if replaced. It’s not uncommon for one or more of the trunnions to be slightly splayed leading to some endfloat which allows the spider to flick from cup to cup twice per rotation, making a clacking noise. The fix is thicker circlips (or beer can shims under the circlips).  Unlike propshaft UJs, which need to be free moving on both axes, driveshaft UJs are best tighter, with noticeable drag even once the caps are tapped back up against the circlips.
    • Thanks.  Noise wise it's not too bad, there's a whine under light load (motorway cruising) but other than that it's fine. With the one exception that I've still not resolved the clicking in the drivetrain at the rear despite now having replaced all 3ujs in the past 6 months or so.  Maybe the nosie is from the diff , or maybe the dodgy trunion was causing it.  Hopefully it'll disappear after I reassemble it this time.  If not I'll have to drive it until the problem becomes sufficiently obvious and hope that happens within limping distance of home!
    • I would say this is about normal for a used diff, and you can't tell where the wear is, it won't all be crown wheel to pinion back lash even with the handbrake on. Is it particularly noisy? My two cents would be that playing with pinion backlash probably isn't a great idea unless you have some reason to think that preload is low, e.g. noise changing between drive and coast?  
    • Remember discovering this myself early in my ownership cycle . Back in those days my local BL dealer (jyst across the street) were able to help. But not on a Sunday afternoon .
    • My spare for the front is a nylon one, probably from about 10 years ago when I bought a pair but never only replaced the bad one, so hopefully still good.  The rear one definitely needed doing after I noticed some vibrations. I'll let you know how the kit installation goes.  
    • All useful bits of information, I agree the order of discovery is suboptimal. One more for you; most trunnion kits sold these days are barely fit for purpose if at all. I prefer the Witor/Superflex polybushes on the front at least. Not cheap but they fit properly and last very well. I believe they are also available for the rear, though I’ve not yet tried them. Bella needs a pair…. https://www.superflex.co.uk/proddetail.php?prod=SF375-1850KSS Might be available from elsewhere too.
