Looks much better with the chrome.

comanche project gone bad.
89 MJ replied to dirtyoldjeeper's topic in MJ Tech: Modification and Repairs
Pretty much all of the interior trim pieces are worth pulling, the rear window, exterior b pillar trim, rear fender flares, tailgate, rear bumper and brackets, pretty much anything that isn’t the same as an XJ part is worth saving. -
You’ve got the carbureted 2.8, right? If so, that looks to me like a mechanical fuel pump. It might just be the gasket that’s bad. If the pump still works properly, I’d just replace the gasket. It’s hard to find a good mechanical fuel pump anymore.

The add a leaf will likely have more arch than the springs in your pack, adding lift. It will also stiffen the pack some, also resulting in lift.

I don't think the tow rating changed based on transmission, but I could be wrong. The metric ton trucks are rated at 5,000lb towing capacity with trailer brakes, if I recall correctly. With the regular towing package, they were all rated for 3500, if I'm not mistaken.

87 Comanche Rock Crawler Project Hell
89 MJ replied to AreWeThereYet's topic in Member Projects: Your Comanches
I think you've got a great plan there. Especially putting a 3 link in the front and ditching the leaf springs. -
You probably could do it, but I don't think it would be fun. I don't even love towing 2,000 pounds with my MJ, but my truck does have a little bit of lift and 31s and I think it needs shocks. And I also haven't flat towed with it, I've only towed trailers. In my opinion, I think the wheelbase of the MJ is too short and the rear end is a little on the light side to feel comfortable towing much weight at speed. I think that the TJ would probably weight more than the MJ and try to drag it all over the road, which a braking assist system wouldn't really help with other than when you're braking. And with the MJ being so light in the rear, I think it would be pretty bad on a 4-6 hour drive. If it were a 1 hour drive on backroads, it would probably be fine, but I don't think it would be very good on the highway.

87 Comanche Rock Crawler Project Hell
89 MJ replied to AreWeThereYet's topic in Member Projects: Your Comanches
Looks like a good project. What do you have planned for it? -
Looks like Tim just linked one. I’ll take a look for others too.
-
If I were you, I'd look for one that mounts to the top of the bed side, not the inside edge like that one. I don't think any truck bed is a perfect rectangle, so finding one the same shape as the MJ will be tough. One that mounts to the top of the rail will let you move it enough that you should be able to get it to work.
-
I'm not one for red and I'm not typically a huge fan of the late model front end, but this truck wears both well. Funnily enough, two of my favorite MJs off of the top of my head are red. I'm exited to watch this video.

Brakes issues on my 90 comanche
89 MJ replied to Jossue's topic in MJ Tech: Modification and Repairs
I was going to say what has already been said, but also, check your rubber brake lines. The break down over time and will let fluid get to the caliper, but will not let it return from the caliper. If you let the truck sit and it rolls fine, but then after use the brakes get stuck more and more, I would lean towards it being the rubber lines. -
Cruise control switch/stalk, can't find one
89 MJ replied to knever3's topic in MJ Tech: Modification and Repairs
What I've had good luck with is cutting the wire off of the thing in the column you are replacing, then tape your new connector to it, and pull the wire through the column. Most recently, I had to do it with my whole turn signal switch, but I'd think it should work for anything in the column. -
Tim is correct, that is your spare tire winch. If you're not going to have a spare under the bed, you don't need it. Don't throw it away though, they are restorable and someone may want it.

Dad is getting his 09 6.0L cleaned up to install in place of the 2000 6.0L. The 09 makes way more power and has aluminum cylinder heads.
-
Dad had to use it to move his 6.0L around for his truck project. It hasn’t run in over a month and fired right up with a little jump.

Taddraughn's 1989 Comanche Progress Thread
89 MJ replied to taddraughn's topic in Member Projects: Your Comanches
Maybe that's the difference. Mine was an OEM one. I'd guess Taddraughn would also use an aftermarket one, so if that's the case, he should be good to go. -

Yes, learn from my mistakes. Don't spend time and money with paint until you know that they fit -
Taddraughn's 1989 Comanche Progress Thread
89 MJ replied to taddraughn's topic in Member Projects: Your Comanches
Interesting. Mine was a stock 96 exhaust manifold and I had to clearance a couple of lower corners on my intake to get it to clear. I suppose it could've been a casting variance with the intakes or a manufacturing variance with the exhaust manifold flange. -

89 MJ replied to taddraughn's topic in Member Projects: Your Comanches
Just keep in mind that the O2 for Renix is in the manifold. Also, you will have to either clearance the Renix intake or the HO exhaust manifold because they will contact each other. Been there, done that. -

Well, with the soot on the intake and the boogers on the manifold, it looks like you might've found your ticking. Yikes. -
87-90 parts manual on ebay for 50 bucks
89 MJ replied to Pete M's topic in Craigslist/Marketplace/eBay... i.e. Not Your Stuff
The seller had two of the 87-90 books listed. I bought the second one. -
I believe its on Marketplace somewhere in MO for $37500.
