Pry bar/large flat screwdriver between diff case and drive shaft. Simply pops out

There is/was a gm repair kit...

I do wonder if all that mess is a result of complete joint failure... not sure if those bolts were actually tight enough

Nige torqued them all to correct setting in mine & Chris`s (Shackeng) presence, then double-checked.

Can't equate this with the careful way this work was done

YUp .. agreed, but Kevin's comment

I would replace all of the bolts. They are stretch bolts, and they may have come loose due to losing their "yield". Also worth cleaning it all up and using a bit of threadlock on the bolts.

may be the key .. they were undone when Sassenach did the rear bearing, then again when the diff was changed, so they have been "stretched" 3 times.

New bolts on order from VX and 5 (!!) new plates as that is all there are in the whole world according to the stock computer ....  I guess reusing one plate won't make that much difference ...

I've had similar bolts (Ford application, on my kit car) work loose once they've been re-used a few times.

I would certainly re-fit with threadlock too.

i dunno about them being stretch bolts, i just did them up german style ie,"gudentite"

Sounds reasonable that they have exceeded their elastic limit. I hadn't realised they'd been off before, but in any case we would not have had access to any more at the time, I think it was a Saturday afternoon IIRC.

This is a useful heads up to any of us who have had these bolts removed for whatever reason. I shall be checking the ones on my TD at the earliest opportunity, as it has had both rear wheel bearings replaced.

Well the replacement driveshafts arrived this afternoon while I was away on the second part of fixing an old clients computer, which ended up being a faulty telephone extension cable and nowt wrong with the system at all !!! explains why I found no fault with it when I had it here !! another 2 hours wasted !!

Many thanks to omegod for the prompt and efficient supply of the parts. Both now fitted and torqued up .. although 50nM then 60° then 15° didn't feel that tight..... they will be checked every oil change now (5000 miles). Ran out of daylight at the end so all its had is a quick trip around the block, no nasty noises, vibrations or abnormal feel at all. Does feel very low at the back end, but perhaps that's because I've spent 6 weeks driving the Disco in a "sit up and beg" seat position, I'll check out the rear shockers tomorrow.

Once again, many thanks to everyone for all the positive inputs and advice, and a huge thanks (and apology) to Daz and tigers_gonads regarding the gearbox. That is being transported down to me in 10 days time and will be wrapped in clingfilm and stored in the shed as a spare, just in case. It now owes me far more than anyone would pay for a 2nd hand gearbox, so I might as well hang on to it.

Nige, given my recent experience of washer failure after only '27K' and the hard work your box has done, I would recommend a gearbox oil & filter change to confirm no sign of the dreaded thrust washer failure. Many sites recommend transmission oil change at 30k.

Thought had crossed my mind .. but the filter and as much ATF as possible (both sumps dropped) were changed at "Guffers Meet" in 2011 at 10400, and it was a sod to do using a full ramp ... I don't think I fancy trying the same job on the drive on axle stands ........

Thats how i always do mine, using a sump pump to empty rear sump makes it easier. I'm doing my 3.2 when I get back from holliers. 32'C here today!

Did you threadlock the bolts to prevent a repeat?

Hopefully that's the end of that then

No worries Nige 

In a year or two's time, you will be laughing about it all
