    Steering Geometry

    loose parts are never a good deal, but that has nothing to do with steering geometry or bumpsteer

    Steering Geometry

    yeh, I think you're right, although I still think the control arm angle is the bigger culprit here

    gas mileage

    :huh: a throttle body spacer will do absolutely nothing for fuel mileage

    Steering Geometry

    It looks like your yellow line(relocated) doesn't terminate at the original track bar axle mount. If you were to redraw the line more accurately, the yellow and red lines would still not be parallel and you would lose some track bar length compared to the current setup. The net result would be...

    Steering Geometry

    bump steer occurring with both wheels hitting a dip or bump simultaneously is the result of steering geometry design issues. When only one wheel hits a bump or dip, the control arms come into play. With the steep control arm angles of a lifted XJ, the axle will move forward on the side hitting...

    Steering Geometry

    It looks to me like that bracket allows for a slightly longer trackbar which is a good thing, not bad. Assuming there are no clearance issues with the trackbar in its present form, I'd also think that having the adjustable end at the chassis end would keep it out of harms way to avoid bunging...

    Lowering a cherokee. GASPP!!

    I wouldn't bet my oil pan (or engine) on that. The stiffer spring rate would make it less likely, but wouldn't prevent it on one of those surprise dips we've all hit at some time or another on a poorly lit road.

    WTF

    probably for the same reason you run fake beadlocks :moon:

    Manually calculate MPH

    for a little more accuracy, look up the revs per mile data for your tire on tirerack.com and plug that into the formula instead of using the tire diameter. Or, as an alternative, you can multiple your results by .95 to allow for your tires rolling radius vs published or calculated size.

    Stroker, & timing, & cams....Oh my!

    Is it possible the routing of the CPS wiring is loose or mis-routed since the stroker was installed? This may result in the wiring rubbing against a sharp edge and wearing through the insulation. Could cause an intermittent short in the signal from the CPS back to the compuda

    adjusting for caster

    I think you'll find that unless both upper and lower control arms are parallel and equal length,(they're not) that both pinion angle and castor will change in droop or compression. If your lift kit comes with lower arms only, they are sized to correct the change in castor angle. Kits that come...

    Is there a EGR regulator?

    and tell all your buddy's too. If you need info on defeating Jeep emissions control systems, NAXJA is the place to go :dunce:

    weak clutch disengage

    the tube that runs from the clutch pedal cylinder down to the slave cylinder includes a section of flex hose that runs fairly close to the #6 exhaust header tube. The heat can cause it fail over time; more so if you have the all to common cracked header which allows even more heat to act on the...

    Minimum amount of caster.

    castor settings are related to steering axis inclination (SAI) and power steering boost. While turning, castor is used to counteract excess camber on the outside wheel caused by high SAI angles. On vehicles with high levels of steering boost (the Cherokee), on-center feel at the steering wheel...

    Thermostatic Air Temperature Sensor

    The one on my '90 preheats the intake air charge to reduce the amount of fuel enrichment required during open-loop warm up mode. The ability to run leaner during warm up reduces HC emissions and provides a modest benefit to fuel mileage. Having it not work wouldn't keep me from driving to work...
