I bought a dedicated remote speaker for one of my CB's that was mounted on a swivel/pedestal. I could hear it fine on my motorcycle, even with my helmet on, at sane speeds. The dedicated CB speakers tend to operate at a range that makes understanding speech better, while audio speakers may not.

Is it coming from the tires or the belts? I've had a belt that is a little loose, squeal when I turned the wheel, the power steering pump causes more drag. Many four cylinder Jeeps actually has a pressure switch in the power steering pump to bump up the idle a little during a turn, larger...

When the computer fails to receive a (pulse) signal from the CPS during starting, it will stop spark and open the fuel pump relay. The fuel pump relay will close for a few seconds normally when the key is turned to run, it seems to be on a timer. If your not getting spark and no fuel...

Not real familiar with the 93 I have a 96, many of the tests are the same, just a slightly different layout. Says in my troubleshooting list that the resistance should be infinite using the 1K-10K scale, this can be important. The Higher the ohm scale used, in my experience, the more error I'm...

I've had 30/9:50X15, 235/75X15, 255/60X15, 225/70X16 on my 96 with no major issues. All but the 225/70X16 rubbed on occasion, either the rear wheel well or the lower control arm. The 225/70X16 seems to work well, doesn't have the sway of large sidewalls, like the 235/75X15 or the 30/9:50X15...

Not familiar with the 2011 Grand Cherokee, but in similar situations I head for the trailer harness hookups. There is usually a fairly large gauge wire running from the fuse panel to the hitch plug for the inside lighting and accessories for a travel trailer. Shouldn't be too big of a deal to...

Usually there is an oil leak at the pinion seal when or if the pinion bearings start to go. The lift makes you suspect the U-joints. If you look very closely at the U-joint you will see a rubber seal around the cap. If the rubber is covered in rust dust, it is likely you need a new joint. I...

The only thing I can think of as a cause, is possibly somebody changed out the seals and reassembled using an impact wrench on the pinion nut. I've heard of many dealer mechanics say that is the way to do it, I remain skeptical. I'm kind of anal about bearing pre loads and when not using new...

I've never had a pinion bearing go on any of my XJ's, D35. But have replace carrier bearings on most, between 130 and 150 thousand miles. I typically run mine at high speeds for long distances and always figured this may be the cause (heat). Or maybe it is just fair wear and tear. I do know...

Another thought, when my battery was going (partial dead cell), there wasn't enough power for my IAC to work reliably. Check your voltage pole to pole on the battery with the engine running. The IAC got sluggish, idle was anybodies guess. Hopefully you cleaned out the seat in the TB when you...

I've had it do that for numerous reasons. Adjust or test your TPS, the flat three pole connector. Check the ground first with an ohm meter, should be very little to zero resistance. Adjust 4.6-4.8 volts in and .8 volts out, if memeory serves me right. The out voltage goes up as the throttle...

Just some thoughts, towing usually uses a lower stall converter, for pure performance I used to try to match my stall speed with peak torque. Peak torque usually comes with your cam specs. Intake also has some bearing, some intakes work better with higher than normal RPM's. High stall...

You can cycle the key three times (last time to the run position) and the check engine light will display on board trouble codes. Not the best diagnostic, but may give you some ideas. Just for the heck of it, try starting it while holding the throttle (gas pedal) at around 1/8-1/4 open. If the...

If I remember correctly there are four wires going to the ignition module. A large yellow, which is 12 volt +/- from the ignition switch, a smaller yellow (or orange I forget) wire which is the trigger wire from the ECU and the green wire which is the tach. wire and black which is ground. The...

If it won't crank the first thing I do is jiggle the shifter a little in park, then try it in neutral. If the neutral safety witch is acting up, this may help. Pretty common for the brushes inside the starter to wear down. You can often get a start or two by hitting the side of the starter...

If you are gassing it when you start to drive and it makes that chunk, chunk chunk sound it may be the chain slipping in your transfer. Possible your parking pawl is adjusted wrong and making contact in some situations. I'd grab the rear pinion and try to move it sideways and look and see if it...

The TCU gets inputs from the TPS and the speed sensor and along with the shifter position, decides when to shift. Been awhile since I saw the TCU inline fuse, if I remember correctly it's about a foot down the harness for the TCU towards the firewall. If you have a holder and no fuse, something...

May be a throttle position sensor. The square plug from the TPS is the one for the transmission TCU. The grey wire from the TPS is the reference voltage, it is often around 4.6-4.8 V (supposed to be 5 volts but it never is), the blue wire is the out voltage and typically right around 4 V...

I looked it up and you likely have a NP 229 transfer, which I've never had to deal with. Just as a test, I'd take off the front drive shaft and put the transfer in lock and see what happens. I'm guessing it is a full time, part time setup. Just on a guess, does your passing gear work? The...
