Re: 1990 Jeep Wrangler Islander 4wd Question
 

Thanks Mike & RoyJ....

RoyJ if you could email some good diagrams to rmcs.david@bresnan.net I
would greatly appreciate it. If you have a similar jeep and could take
a photo or two of your engine showing the lines in place and where they
go that would be a great help to go with them. I have some diagrams
but being more of a visual person the actual thing would help put the
diagrams to better use as well.

THanks all for the information and if others have more to add great.

If the computer has been disabled, you can save about 5 miles of vacuum
lines and just hook up the 'needed' items for good running.... PCV,
charcoal canister (gas tank and carb vent), EGR, distributor advance and
air filter flaps for the heat pipe for good winter running.

You can tell by looking at the plugs on the ignition module 'waaaayyyy'
down under the washer bottle on the fender. Look at the 4 wire
connector and see if the purple wire has been hooked up. If it has,
then the computer has been put to sleep, if the purple wire just
terminates at the plug, then the computer is still in there and it needs
a ton of vacuum switches to work right.

Re: 1990 Jeep Wrangler Islander 4wd Question
 

Thanks again to Mike & Roy....

So a question I have then. If i don't hook up the stock vacuum 4wd
what would be a good option that doesn't cost a lot of money to set 4wd
back up on my Jeep. I've heard that the stock 4wd had some issues when
getting wet or cold with the snow but not sure how common those issues
are. Knowing my luck recently I'd encounter them though. I've also
read where some guy rigged a chain with a lever to engage the 4wd but I
don't want to do something like that because it seems a little worse
off than the vacuum idea.

I thought I had read for $200 - $300 I could get a 4wd conversion for
that jeep or something that would work out quite nicely and be better
than what it came with and very reliable. Am I correct or just
hearing/reading crap out there? I don't mind spending to much to get
some good reliable 4wd because I do want to do some trail rides in the
mountains of Montana here. Other things that I know I need to get done
are the sway bar and bushings but not sure what else to look for
underneath. The sway bar bushings (if i'm saying that right look
horrible), and I've noticed the steering wheel kind of jerk or jiggle
when driving at times, not to much give in the wheel while turning
which is nice but more jerking type stuff when going over the tiny
lines made in the road. If that makes sense. I've been putting a good
shopping list together and hoping to order some things next week to get
moving. I appreciate any and all suggestions but don't have unlimited
funs for the "toy" either. I do have a hard top so one of the items
will have to be a bestop bikini or something though when I take the
doors and hardtop off in the spring/summer for crusing around.

Thanks again all.
Dave

Re: 1990 Jeep Wrangler Islander 4wd Question
 

Most of the front axle discconect issues tend to be in the vac lines,
the plugs, and the vac switch on the transfer case. The vac motor on the
axle does go bad but not very often. The fast and dirty way to get the
front axle into locked mode is to run a vac line from most any vac port
on the engine to the center port on the axle vac motor. This will
permanently lock the axle in 4wd mode. More wear and tear but this is
the same mode as all the TJ's ('97 and up) use. Or you can spend the $$
and get the cable disconnect kit.

The steering wheel 'jerk' is worrysome. It could be that you are not
used to the Jeep suspension and it's very tight turning radius. Or it
could be loose/worn suspension parts. Sway bar bushings are not that
critical, you do need them eventually but even mushed ones still work.
Have an alignment shop take a good look at the front ball joints, tie
rod ends, etc. You also need to find and inspect all 6 'U' joints. On a
'90, they will be likely be either already replaced or shot.
