View Full Version : The good bad and ugly about an '84 G-Wag
02-18-2007, 05:58 PM
Im looking at an '84 G-waggy. 360/727/QT
I need to know the good/bad and ugly about these less-than-gracefull but ballsy machines. I own a TBI Comanche and being 17, never played with a carburated motor except the roto-tiller and the lawnmower. Im sure I can handle choking it for cold starts and such, but any normal little problems, like what breaks, what causes odd things, like that. Id love to know. Thanks!

I had an '89 Comanche. Now I have an '88 GW. It would eat the Comanche if I parked them side by side. Pros are it's got a stout drivetrain, it's made of good old American steel, it's the coolest rig on the road, and if you own one you get to hang out on this forum. Cons are, it'll probably be a money pit and dominate more of your time than you intended. But you have a Comanche so you already know about that. You can TBI a GW if you have the $$$, but carbs aren't that bad once you accept the fact that they run on voodoo. On a side note that '84 does not have Q-Trac. It has Selec-Trac, NP229. Viscous coupling, selectable between 2H, 4H (full time), N, and 4L (part time). Most guys who have it don't mind it, I got rid of mine. If I'm not mistaken '83 and '84 were the years with vacuum disconnects on the front axle. That can be troublesome if you're not familiar with the theory, but once again you have a Comanche so you probably know all about it. If I'm off on the years for the CAD someone smarter than I will correct me soon. Check the rear window for proper operation, check the rest of the power options too. Odds are the rear window will stick and the power door locks will suck. Get gas when it says it's got 1/4 tank unless you like pushing SUVs. Cruise probably won't work either. This can all be fixed.
It'll choke itself when you start it as long as it's working and adjusted properly. If you have emission testing in your area check for a crap load of stuff under the hood or you'll have trouble. You should have tubes coming from the exhaust manifolds, a diverter valve, a smog pump, I think some check valves, and a tube going down to the cat converter. Oh, and put up some pics.

I have an '84 GW, most of the 80's rigs are generally the same. You'll have an NP229 transfer case, not Quadratrac. It is however also a fulltime limited slip case, but it has low range and locked center diff in one function. The front axle is a vacuum disconnect unit, you must come to a full stop while in gear before switching to 4wd, or it will be broken. To switch to 4low you must be moving slowly in neutral.
The 2150 carb has an automatic choke that works nicely so long as it is clean and set up properly. The carb is a very good one, often gets a bad rap for no good reason, works excellent if clean and properly set up, it's great on angles.
Your biggest worries will be rust, annoying (but usually minor) electrical issues, and poor maintenence from previous owners. Once you've got all the little issues sorted out they're generally very reliable rigs.

The PO is acctually a member here. Sounds like a solid beast. my MJ is a 2wd but ive heard lots about the vac disco's with MJ's. Im handy with working with jeeps, trust me. I rebuilt crap on my MJ before I got it roadworthy.
Smog is 87 and newer, thats why Im glad its an '84. can I operate powerlocks without power? Ok. dumb q, yeah I can haha. Im so used to manual everything. Rear window prolly will never get used. it'll be my dd. Im going to get as many pics as I can, its about 2 hrs away from me, so I may have to take a weekend or something to go check it out. Frame is the most important right at this moment for me.

The pro of the front axle disconnect is when in 2 H, it might save a little fuel and some wear. The con is its another thing to go wrong.
Heck, the carb is the easy part, its all the emmisions that make your head swim. Everything is vacuum actuated with a bunch of temerature senseors (CTOs) and other clever? devices to say when and when not. If everything is there and hooked up correctly, you're doing better than many of us when we bought ours! See if the vacuum and emmissions diagram is under the hood.
Check for rusty frame rail along side the fuel tank skid plate. They always rust, and the repair requires dropping the fuel tank along with buying a new skid plate. Also for rust around the body mounts in the rear.

You'll use that back window eventually. You can't open the rear gate with it closed.

Meh. Back doors open fine. I can always swap it to crank handle or something, can't I?

Yep if you can find one. Sometimes the motor isn't the culprit. In fact, the motor is usually not the culprit. Just buy it, you know you want to. Do you hang out on the Yahoo Comanche forum now? We're waayyy cooler than the Comanche guys.

Im acctually on http://comancheclub.com under the same username
you guys are one in the same, really. Its not a big, e-weenie fight like some forums are. CC and IFSJA are just down-to earth jeep forums and I like'em both haha. We all drive heeps, can't we all get along? :)
I know I want this Wag bad, but I really have to weigh my options on the money side of things.. Im not ending this year without an FSJ so if the owner of this wag keeps it (as he has said he will if its not sold by spring) Ill gladly purchase it in the summer, Ill have better finances and more time to make the 2hr run to see it/pick it up.
