100% accurate. Thats the reason I check voltage only at the battery. The gage however gives an idea as to whether or not the alternator is working but not the system voltage.

A good battery usually sits at about 2.1 +/- volts per cell. A good charge rate will be about 2.3 volt per cell. There are 6 cell in a 12 volt battery. Your battery is in good condition. For my AGM batteries, I aim for 2.35 volt per cell which put the charging at 14.1 volts at the battery, and...

I appreciate the comments and experiences of thse who have posted. Thank you. The Dough Thorley had good reviews years in the XJ crowd. many liked the long tube version especially regarding the low RPM torque. On my previous XJ, I had the Borla headers with the down pipe which I liked very...

I need a replacement exhaust manifold for the 4.0 L. So far the banks Torque Tube and Revolver come to mind. The prices are a bit too steep although not unattainable. Banks site shows the increase in HP and Torque. In addition to these, what other advantages and disadvantages are there...

I am about to do a comprehensive tune up on my XJ after finally getting the new-to-me front diff dialed in. AT present it runs rough at idle and pings at adle and off idle except if I am hard on the go pedal. The issues are both fuel and spark related. How could it be both? Two plugs center are...

I have just about given up on the weird steering on my XJ. I have visited and re-visited every bolt, nut and tubing up front but cannot identify the cause of the sharp but short steering wheel jiggle that only occurs between 25 and 35 MPH. It is not RPM related. It occurs both when coming up to...

Great write up 75SV1. Since I have never done engines that have a bar through multi rocker arms it is all educational for me. Back when I was a power boat mechanic all engine rebuilds, I did and tuned were the Chevy blocks both the 350 and 454 cubic inch-based engines. Each rocker arm had its...

Reading your post again, I begin to wonder is you have installed solid lifters if such a thing exists for the 4.0L. I have not done any head or valve work on my XJ so cannot help you there. The deepest I have dug into my XJ was to replace the timing chain and gears. Post up some more...

To be sure the cam timing is correct, you need to remove the valve cover and rotate the engine in the normal direction of rotation. While doing this, look at the valves for both cylinder #@1 and #6. When the timing mark on the vibration damper begin to come into alignment with the marks on the...

Check the timing again. You may have the camshaft timing off by 180* or you are checking the wrong cylinder. At a certain position close to TDC both the intake and exhaust valves are open especially on larger cams that have huge overlap. These are the cams that don't like low RPM idle.

I have made some progress, but the steering wheel vibes are still there. I have replaced the front tires with some newer JK take offs and the tire wobble is gone. Added more caster which improved the return to center (but it's still weak). It now drives straight down the road with no...

Actually, yesterday I changed the front tires to some I had on the garage floor complete and ready to go. I did have 2 sets of JK takeoffs in my possession. The steering shimmy is gone. Now, I have to add a few degrees of caster to bring it to specs and road test it again. Yes, there is a bit of...

Just installed a Wrangler Rubicon D44 in my 1996 XJ. Now there is a vibration felt in the steering wheel. There is no shimmy ir bump steer, just an annoying vibration from 35MPH up. New parts so far: All new brackets that are needed including: Brackets for the lower control arms, New spring...

Jeep JK. They are 5 X 5 bolt spacing.
