Thanks for the info Eagle. Once again the forum has come to the rescue for me. The shift motor solved the noise problem, however, when I took it out for a test drive I was still getting a lot of shaking and shuddering when I got to around 25MPH. It feels like I have a loose wheel because the...

I have a stock 5 speed, 89 Cherokee 4.0L. I had been noticing a grinding and squealing noise when the wheels were turning. It seemed to go away once I hit 3rd gear. Then I started to feel the whole Jeep vibrate when I hit 25MPH. I parked the thing and pulled the hubs to see if the bearings were...

You have a very good point Willis, I don't want to be burning down any forests. I guess I'll look into a nice moderately quiet high flow muffler. Does anyone have any suggestions on where I might find one online? What about a direct fit high flow cat? Thanks for all of the useful info.

I've heard of many people who remove their muffler and run a straight pipe from the catalytic converter back. I was thinking about doing this but I do not know how loud this would be. I like to hunt in my vehicle and I don't want my Cherokee to scare away every living animal in the forest. I...

Thanks for the info. The main reason that I do not want to mess with the OEM sensor is because I do not want to interfere with the electric fan operation. Which sensor is responsible for the fan operation?

I have an '89 Cherokee, 4.0L. I want to install an aftermarket temp guage and noticed that I cannot connect the OEM coolant temperature sensor and the aftermarket sensor from the same port. I have read that later model XJ's have their sensor at the thermostat housing. If this is so could I...

If the arrow was pointing up and you have a manual transmission then that, I believe, is the shift indicator light. It's supposed to tell you when to up-shift but mine is never right.

This is probably a dumb question but since I am new to the XJ game there are still a few things I need to know. I have a 1989 Cherokee, 4.0L, with 5sp Manual tranny. I do not know what tranny is in this vehicle. Is it a Peugot? Was there more than one kind of manual tranny available for this...

Have you checked the connectors at the top of your brake pedal linkage? Mine once did the same thing and it turned out to be a disconnected wire.

Thanks for the info guys. I have now started to notice that the ticking continues after I turn off the engine. When I remove the key it ticks for about another minute then slows down to a stop. Any ideas???

I hear a light ticking/tapping sound coming from the top of my engine. It sounds like it is coming from the intake manifold so I'm thinking maybe it's the fuel injectors? The ticking seems to move up and down the length of the engine and it's consistent. Do injectors make that much noise or am I...

I have read a few posts that have said that pre 1991 XJ's did not have a system capable of producing diagnostic trouble codes. I was recently looking over the manual for an AutoXray and read that "...beginning in 1982 and by 1989 all new cars and light duty trucks sold in California had to have...

I switched because a friend of mine told me that when he switched he had a noticable improvement in gas milage and a smoother idle. As far as I can remember the knock was not present before the fuel switch. I did a tune-up yesterday (plugs, wires, cap, rotor) and that helped a little with my...

My 89 4.0L Cherokee w/108k miles has begun knocking/rattling from the exhaust manifold. It seems to me that this bagan when I upgraded to 91 octane fuel. Could the increase in octane be responsible for this noise. Any info is appreciated. Thanks.

I've got an 89 Cherokee 4.0L with 108k on it and lately I've been hearing this rumble/rattle that I initially thought was a bad electric fan but it seems to be coming from the exhaust manifold area. The sound begins when I start the engine and does not ever go away. I just recently bought the...

Wow!!! Those are some impressive numbers. I am new to this board as I have just purchased a 1989 Cherokee with 106000 miles. This rig is in near perfect shape and I now know that I can expect many years of enjoyment out of her.
