Hi think Nige has done a Sterling job with this video on this subject.

Yes, Nigel's done a good summary of the situation.

Great to see his method of measuring the alignment. Thumbs Up
Of course, it's all out of the vehicle and partially disassembled to do it, but it can done.

Interesting to see a 'good' transmission assembly was showing a 12 thou' run out. That is a 6 thou' offset between the gearbox and transfer box, or 0.15mm.
Now there's a possibility of measuring the offset and relating that to the failure milage, but I'm not hopeful that anyone else will go to the trouble of doing it. Wink

- Perhaps, if you had a vehicle that is badly misaligned, you could set it up on the bolts and clock it in true, then remachine one set of dowel holes to keep it that way. Very Happy

Yes, that's a nice vidéo. Of course, everbody knows that the grease cannot be confined inside the spline with a rubber seal.
It must be renewed -

Unfortunately this cannot be done easily (because one cannot access that spline within 5...10 min or so.

That's why I cannot accept Nige saying the output shaft is "good design". Land Rover engineered it badly. Neutral
I appreciate the solutions trying to help us out (LOF, Ashcroft) and had the Ashcroft kit installed.

And I'm hoping that in near future somebody comes up with the perfect solution !

Great video by Nigel.
Could have checked for angular misalignment by placing the dial gauge on the mating face of the tcase. But parallel misalignment is probably more at play.

Wonder if the same measurement can be done with the tcase in situé, by removing the tcase input gear, mounting the dial gauge on the intermediate shaft itslef, and use the lt230 input gear rear opening as reference. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

I don't see why not, but I'd try to use the rear bearing outer race rather than the transfer box opening. It might even be possible to check with reference to both front and rear bearing races.

One try at the next opportunity I think.
