1986 97+ trans crossmember mounts.
Eagle replied to MJEspi's topic in MJ Tech: Modification and Repairs
I favor Clayton's longarm kit. I've met and wheeled with Clayton, so I know his engineering is both solid and based on his own real world experience, and I've seen his kit being installed and I know it's good quality kit.- 7 replies

My sister had a Siberian Husky. Hah! I wrote "my sister," but she was still living at home, so it was the family's dog. Don't know if it was just that dog, but she could NOT be housebroken. And she could not be allowed outside without being on a leash or a tether, because she'd be gone in an instant ... and, unlike other dogs we had when I was a kid, she wouldn't just do a tour of the neighborhood and then come home. If she got loose, we'd be lucky if she only got as far as the next town before someone found her. Husky's can be great dogs, but they're about as close to being a wolf/dog mix as you can get without having to actually call it a wolf/dog.

Especially if your pockets aren't deep, why do a lift at all? How do you use the truck, and how do you plan to use it in the future? Are yo aware that you can run up to 9and including) 31x10.50-15 tires with NO lift?

Retractable Under Hood Light
Eagle replied to Drahcir495's topic in MJ Tech: Modification and Repairs
EagleScout526 has it right. Near the passenger side firewall, in the vicinity of the blower motor. -
But you stated that you have no basis for comparison. I do. KYBs suck.
-
True. I tried the KYBs because my brother thought they were the greatest thing since sliced bread. (My brother had some very strange notions about ride and handling.)
-
Makes sense. Your plan sounds solid. Get the grounding and bonding squared away ASAP, and then get busy rewiring circuits as soon as you possibly can. I'd suggest that you start by removing those unused 240-volt circuits in the kitchen.
-
Oh, dear God! I put a set of KYB Gas-A-Justs on my '88 Cherokee a long time ago. I think they were on it maybe a month. HORRIBLE, HORRIBLE, HORRIBLE! They were vaery harsh over pavement cracks and small bumps, and had almost no damping over large bumps. Just awful. I couldn't get 'em off the XJ fast enough.

Did you happen to ask the maestro about running a megger test?
-
Yeah, that's the speed controller for cruise control. You don't need it. One more thing to break. Just buy the straight speedo cable.

Step number one to address sag is to determine whether or not the rear has actually sagged. Read this thread: https://comancheclub.com/topic/11098-how-to-measure-ride-hight/

What's your idea of "a good size" lift kit? The choice is very dependent on your intended use of the truck. Personally, after wheeling an MJ with a 4-inch lift, I think the best lift is zero. (I took the lift off and returned it to stock height, and it didn't affect where I could go off-road very much at all.)

Thoughts on gear ratios for highway use?
Eagle replied to Minuit's topic in MJ Tech: Modification and Repairs
When I bought the 3.73 gears that ended up in the '88 MJ, they were intended to be used in the '88 Cherokee, and they were intended to be used with 30x9.50-15 tires. 30x9.50s are very close to the diameter of 235/75-15. I think that's a good ratio for street driving and highway driving with tires of that size. I wouldn't go to 4.10s unless I planned to run at least 31" tires. Your criterion seems to be 80 MPH, so let's look at that. 3.73 gears with 235s would have the engine spinning at 2,697 RPM at 80 MPH. 4.10s will have you turning 2,964 RPM at 80 MPH. The latter will give you better performance, but I don't know if it will give you better fuel economy. I couldn't find any horsepower/torque graphs for the 4.0L HO engine. My guess is that it won't be much different regardless of which you choose, but it's probably easier to find axles with 4.10s than 3.73s. -

Eagle replied to Minuit's topic in MJ Tech: Modification and Repairs
I found revolutions-per-mile for 195/75-15s. https://docs.google.com/spreadsheets/d/1pHFuhGgj6dQDfzyfFJH5z7NCDLW2KX3ABQgAJr3lBvM/pub?hl=en&hl=en&output=html Actually, much closer to 2200 RPM. 2448 would be for your factory 195/75-15 tires and 3.55 gears. To match that with 235/75-15 tires you are mid-way between 3.73s (2360 RPM @ 70) and 4.10s (2594 RPM @ 70). -
Keep in mind that there are two ways of regulating the temperature. The old AMC vehicles that used that valve used the valve to control how much coolant was flowing, which regulated how much heat was available to be transferred to the air stream passing through the heater coil. Newer vehicles (like newer buildings) tend to control the temperature by "variable air volume." Instead of regulating the flow of coolant, the newer vehicles (including the XJ and MJ) use a system of baffles that passes some of the incoming air through the heater coil and some around it. By varying the air mix, the system controls the temperature. VAV is supposed to be better, but IMHO the old system worked just fine and I never understood why the car makers moved to the significantly more complex VAV systems to accomplish the same task that little valve was doing. My point being that, with that valve, you have the potential to have two means of temperature regulation possibly fighting each other. I'm not sure about that -- they might play together very well, or you might find that you need to use that as an ON/OFF control and use the VAV controls for when the valve is on HEAT mode.
-
That's it. If you don't want to bother with the cable, just install it and open or close it from under the hood when the season changes. That valve was the factory heater valve in all AMC cars in the 1960s and 1970s. It's variable volume, so with the cable that's what controlled the amount of heat you got. Full open ==> full heat. Throttle it back for less flow to produce less heat.

Had the WJ aligned and camber is off
Eagle replied to Smokeyyank's topic in MJ Tech: Modification and Repairs
I thought caster was adjustable on the WJ. Unfortunately, I gave away my WJ factory service manual. You can always go to adjustable control arms. And camber can be addressed with offset ball joints. -
Had the WJ aligned and camber is off
Eagle replied to Smokeyyank's topic in MJ Tech: Modification and Repairs
The difficulty is quantifying the change ... but maybe it's not that difficult. Assume you start with the axle perfectly upright -- defined as zero caster measured through the ball joints -- and +1.5 degrees of camber. As Pete noted, flip the axle 180 degrees and the camber shifts to -1.5. As the axle rotates through 90 degrees, the camber would be zero (it would actually then be creating toe-in or toe-out). So let's assume that the change is linear. Rotating the axle 180 degrees causes a change in camber of 3 degrees. So a shift of 60 degrees will change the camber 1 degree, 30 degrees will change the camber 0.5 degrees, and 15 degrees on the axle will change the camber 0.25 degrees. 5 degrees on the axle will be 0.0833 degrees of camber. Your caster angles are roughly 2.35 degrees off from the mid-spec of 6.75. If the mid-spec for camber of -0.1 coincides with the mid-spec for caster, then the 2.35 degree shift in your caster would change the camber by about 0.04 degrees. If you started at mid-spec, that would still be within the allowable range. However, if you started at or near one of the extremes, it would push you out of the allowable range. -

Yes, it does. It has to.
