How hard do they turn (new) after you torque them down? If you can't turn them using, say, three fingers on the wheel studs, they are likely too tight. When I put my Moog hubs in and torqued them to specs, they turned way too hard. My solution was to torque them down to five pounds over, them...

The only time I'd think about a rebuild is catastrophic failure or very low compression. Remove the small air vent line from your valve cover and blow through it, it is likely plugged. Then blow through the hole into the valve cover, it is also likely plugged. Check out the vacuum line to your...

I'd address the smoking issue first. Run your finger inside the exhaust end opening and see if it comes out oily. Smell the exhaust, does it smell like fuel or oil? Pull a few plugs and see what they look like. Take the oil filler cap off and see if pressure is coming out the hole. Lightly...

Anytime you open the closed system 87-90 you are liable ot get some air in inside. Various methods for getting the air up to the canister, none of which work very well. I've had reasonable luck crushing the top radiator hose repeatedly while the motor is running. If it overheats at idle it is...

I'm with Steelheadz, three distinct Possibilities, either a short in a harness, an odd ground path or a component that is supposed to have resistance that has low resistance (or almost no resistance) and shorting the ASD circuit to ground. My 96 will run very poorly with the ASD circuit open...

GoJeep had a nice writeup on a quick do it yourself alignment. I've been using it for years, part of my regular front end check for loose joints etc. Alignment

I'd use the key method and pull the MIL codes from your PCM. If you have a shorted sensor it should show up there, though theses codes can and will lie to you. A likely spot to overheat the ASD may be the O2 sensor heater. It should have a resistance, though I sure can't tell you what it...

Messing with the doors on an XJ messes with the integrity of the body, in more than one way. Roof strength and frame stiffness/strength. The "A" pillar is weak anyway, it really doesn't take much to flatten the roof from the end of the hood to the "B" pillar. The "B" pillar is fairly strong...

A lot of places the steering can be loose. Often it is a little here and a little there that adds up. If your steering wheel isn't pointing straight up, when the tires are straight ahead, this can be a loose trac bar joint. Worn ball joints and tie rod ends can also add to the problem. Even...

I'd try to figure out if the electric or the pump is the problem. Figure out someplace to hook up a voltmeter and watch it when you turn the key to run, while your cranking and after it has started. If you have a ballast resistor jump it, won't hurt a thing. Typical symptom is it will start...

The dark green and orange wire going to the coil should be hot with the ignition in the run position. The black/gray wire is the trigger wire and is fired/triggered (grounded) at the PCM. You can hold the high voltage wire near a ground, about a quarter of an inch is usually good and ground the...

I'd get a fuel pressure tester, simple pressure gauge and hose that hooks up to the test nipple on the fuel rail. If the 92 is the same as my 88 the fuel pressure should be around 31 PSI with the fuel pressure regulator vacuum line hooked up and 39 PSI with the fuel pressure regulator vacuum...

There is a test valve on the fuel rail. Can you hear the pump run for a few seconds (prime) when you first turn the key to the run position? The pump should also run continuously as long as the engine is cranking. It won't run continiously with the key in the run position, it only runs for a...

If the cable is jammed, you may want to try something like this. Motion Pro Cable Luber - Dirt Bike Motocross - Motorcycle Superstore I figured out by accident it works well for parking brake cables, likely to be handy for other cables also. Most motorcycle shops carry it.

I'd start with the easy stuff, normally when starting you shouldn't touch the gas pedal. The IAC is supposed to do all the work for you. If the IAC is stuck closed, it can flood the motor. Try starting it with about 1/8-1/4 pedal, keep your RPM's up, then release the pedal. If it dies, it may...

The out wire from the fuse block for the blower circuit, is Yellow/violet ? Yellow in most Jeep circuits means current from the ignition switch (switched current) violet is the sub system (blower circuit). I usually divide and conquer type circuit troubleshooting. Start at one end or the other...

The brown wire from the ignition switch to the blower fuse in a known trouble spot. The brown wire where it comes out of the ignition switch connector often burns the connector kind of dark brown or black. After the brown wire comes out of the igntion switch connector it looks like it goes to...

I get no spark and I usually head for the CPS. The wiring in the early XJ's can get kind of iffy, along with the grounds. The grounds at the dipstick holder and the grounds from the back of the head to the firewall. I periodically disconnect about every connector I can find in the engine bay...

Usually the long spring with the eyes gets a bow in it (near the end). If it isn't bowed too bad, I'd get a full length add a leaf. Not that big of a deal to cut the U-bolts, remove the centering pin, stick a new long leaf in there, new U-bolts and a new centering bolt/pin, a couple of new...

I don't think there is an inner seal on the 35, the outer axle bearings are lubed with the oil in the differential. I'd check and make sure it is diff oil and not a leaking brake cylinder. The leaking brake cylinder is a lot more common. Pull back the rubber boot on the brake cylinder near the...
