Re: 87 YJ 4.2 -> 4.0 swap questions
thanks earl - a few questions then:
can i take the fuel pump out of the cherokee and install it into the
YJ? and what if i was to swap out my entire engine/TC/trans with the
one from the cherokee?
wouldnt that eliminate the need for installing a CPS and the adapter
plate? i suppose i'd need a different driveshaft... and perhaps front
drive shaft?
and the springs?
thanks for your help...

The full time is Quadratrack. It has only 4hi-N-4lo

Re: 87 YJ 4.2 -> 4.0 swap questions
The fuel tanks are different, so you can't put the pump from the Cherokee in
the Wrangler tank. Now I don't know whether the Cherokee tank fits in the
Wrangler, but I do know that you need an FI tank to make the 4.0 work. An
external aftermarket pump will "work", but as I pointed out they are
problematical.
Before thinking about swapping the entire drive train, you'd better get out
a tape measure and see what is what. The Wrangler drive shaft is too short
as it is, as people find out when they install lift kits. If the Cherokee
engine mount to TC tail shaft distance is longer, then it won't fit. If
it's a Selectrac, it "really" won't fit. I haven't made this measurement
myself, but I am pretty sure that you will find out, that the Cherokee drive
train is too long.
Wrangler springs from www.4wd.com are not too expensive. The stock springs
on a Wrangler are pretty flat, so your existing springs may not be as bad as
you think. The best way to get the old bushings out is with a gas wrench.

Re: 87 YJ 4.2 -> 4.0 swap questions
thanks all.
Earl - can i ask you to clarify some things?
1st off - i am clueless as to the nature of the 'Selectrac' and
'Quadratrac' so what l do i need to look for to detemine their
presence? 2nd - besides the driveshaft length - which is pretty
obviously different i would imagine - can't i just swap my tired old
Peugeut 5sp with the AT that comes with the Cherokee? since this is the
tranny and TC that comes with the motor, it would thus eliminate any
need for adapters for the CPS, as well as the problem of pilot bushing
mismatch, and for finding a 4.0/5sp manual computer... isnt that right?
all i would need would be a YJ driveshaft with the correct spline count
yes? i assume my stock (5sp) shaft wont fit - correct?
sorry for all the questions, trying to figure out if this is a good
idea...
cheers,
bennett
