Good Morning , I am breaking a 1988 Daimler XJ 40 3.6 litre and
have had a query from someone who has a 1992 Daimler 4.0 litre
needing a new differential. Will the one off the earlier car be a
straight fit and would the ratios be the same.
Thanks

Gerald,
The diff ratios are close - 3.54 for the 3.6 litre and 3.58
for the 4.0 litre which is really of little consequence -
but the possible major difference could be in the input
shaft flange.
Does the '88 model have a Jurid (rubber) coupler between the
prop-shaft and the diff (three-leg flange) or does it have a
U/J joint? The '92 4.0 litre will definitely have a Jurid
coupler - and you cannot fit the former to the latter
without changing the prop-shaft too - and then you may get
in to compatibility problems.–

Gerald, there are so many versions of the prop-shaft across
the various models and VIN dependant both with and withoput
Jurid couplings that I don’t know.
Perhaps you can work it out by perusing the JDHT parts
catalogue - I can’t!
