Re: Engine swap
Hey thanks. I read that the 4 cyl transmission was crap anyway, not really
strong enough for the 4 cyl! So now the transplant is getting a bit more
extensive but not too bad yet. How about the transfer case and
differentials? Did they put wimpy ones behind the 2.5L? Would they have to
be replaced? Should he just buy a different rig? Don't mind doing the work
but maybe starting with the 2.5L rig is not a good spot to start?

Re: Engine swap
The AX-5 transmission failures that I have heard about seem to involve over
use of fifth gear. Even with the stock 4.11 axle ratio found with the 2.5
liter engine, fifth gear is all but useless except in a tail wind situation.
Imho, the best engine for this vehicle is another 2.5 liter engine.
The transfer case and differential are the same as are used with the six
cylinder engine, except for two differences. The transfer case input
shaft/gear would have to be swapped with a longer part to use it with the
AX-15 engine. This involves disassembly of the transfer case. The
differentials sport 4.11 gears (actually 4.10 front) which is close to the
optimal ratio for most applications. Although the D35C rear axle is not
exactly "wimpy" many prefer the heavier D44 or a Ford 9-inch axle from an
Explorer. Bill has some pics of D35C axle C-clip failures that you might
want to look at.
This vehicle with a six cylinder engine would be a decent rig, but I am not
sure it would be worth the effort required, unless you find that wrecked
vehicle you were talking about. For an off road vehicle, or even one used
in a rural setting, the main thing you are looking for in an engine swap is
reliability. The 2.5 liter will sip fuel on the trail and idle all day
without overheating.
