Default Guess what this contraption is then help me figure out why it squeels

I've posted pictures of the outside of this thing for a couple times on here. It's a jeep, I haven't ever been told what year or model it is though.

The main reason I'm posting this is because it has a really bad squeal when it warms up.

Anybody want to tell me what this is and if that model had a squealing problem? I've tried to track down all the vacuum lines but haven't had any luck stopping the noise.

Post some pictures from underneath, but that looks like a 1972-1975 intermediate CJ5.

If its an intermediate, then you should have mostly open C-channel frame rails that are straight from front to back. They'll be boxed in the front area by the motor. You'd have 39" long front springs/45"long rears, that are 1.875"-2" wide. Front would be an open knuckle dana, rear would be a centered dana 44 with 1 piece shafts, gears would be 3.73 or 4.27. Your transmission would be a T14 3 speed or T18 4 speed, with a dana 20 behind it.

The 6 cyl AMC motors weren't introduced until 1972, nor were hanging pedal.... and then in 1976, the steering columns went to GM ones with integrated turn signals, ignition key in the column, speedos with numbers ending in 5, etc...

So you've likely got a 232 or 258. Both were available in those models. Have you tried removing the belts from the front temporarily to see if the water pump or alternator are the culprit?

Yeah, our maintenance guy is creatively redneck.

Haggar, I may try the belt thing tomorrow during lunch. Thanks!

Looks like a 258, but I've never had the opportunity to get familiar with a 232. If it isn't a belt or accessories I would check vacuum lines for a leak and the intake gasket. By buddy's Jeep would whine and squeel when his intake gasket went out on his 4.0.

Better description of squeal and location. Metal on metal, belt on pulley, air whistling?
Front, rear, underneath, during acceleration, at idle?

Sounds more like air whistling. Near the Carb side of the engine.

The usual trick for finding vacuum leaks is to slowly spray something flammable like carb cleaner or starting fluid along the areas that you suspect a leak. If there is a leak, it will be sucked in, and the rpm will rise.

^ A handheld propane torch (not burning) works pretty good also.

You have to use the right weight elbow grease to keep those functioning properly. It took us a couple months to figure out.

It actually has muffler fluid. No joke. It drips diesel ( or any fluid) in the exhaust manifold to create the illusion of smoke. Been trying to figure out a better (cleaner) burning alternative for that too.

Intake gasket is leaking most likely.

Try smoke oil or home made smoke oil, you'll find all sorts from bio-diesel to baby oil.
Mostly for rc airplanes but the same concept.

Took me 2 years to figure it out on mine becAuse it would only do it in the cooler weather, and only for a minute or two every once and a while.

I'd try the easiest, free methods first. Take belts off like previously posted. I would first try taking of the air filter and seeing if that's the culprit
