#4 of 25 Re: Front Outer Axle Boots Leaking [xyclonis] by atfdmike

Hi, It is not unusual for the outer axle boots (bellows) to eventually crack and leak lubricant (CV grease). What is important is whether or not the CV joints are clean and not making any noise or clunking particularly when turning. If the only problem is the tear or leakage of the bellows, then there are aftermarket boot kits which don't require the removal of the axle or disassembly of the joint to replace the boot.
Opinions will no doubt vary on the quality of the product, but as a stop gap solution, this would be the way to go if you do not want to tear down the vehicle.
A full line auto parts store should have or know where to get these boots. Basically, you remove the old rubber boot and clamps, install the replacement boot kit which has (typically) an overlapping seam that allows installation around the joint and new clamps that keep it closed and in position once it is closed around the joint.
My experience is that the worst part of the installation is the removal of the old clamps that hold the original boot on the axles. You also need to regrease the CV joint while you are in the process of putting the replacement boot on. If you have some mechanical ability and tools, this is not an impossible job. Otherwise, a mechanic,not necessarily a dealer, would be able to do this for you as well.
Here is what alldata says about the original parts and labor time, which might help you decide if you are getting ripped if you go to the dealer:

For a dealer under warranty, they were allowed about 4 hours per side and the parts cost to perform the work...so about $440 for parts and 8 hours for the replacement of 4 boots and both axles. Dealer per hour charges vary. The replacement aftermarket boot is definitely cost effective. Look around. One owners opinion!!
Good luck.

Expensive but I saw a site that rents access to info for $20/day.
I just bought '99 Trooper (69,000 mi) in May. I check the oil every tankfull and have an OBD II scanner for piece of mind. Right now have code P0440, which I believe is an indication that the EGR system needs attention. Looking for info on how to R/R.

#7 of 25 200 Trooper Code PO1310, What does it mean? by Tmac by tmacias

Mar 05, 2007 (8:47 pm)

My mecanic and I were working on my 2000 trooper, changed timing belt, serpentine belt, starter, spark plugs and fluids. Now none of the left cylinders (3.5 V6 engine) are working and we get a code PO1310. There is spark going there but for some reason it is still missing. Any help will be greatly appreciated. Thanks.

Circuit Description
The Power Control Module (PCM) checks the validity of the signals used in the ION Sensing module at the following engine operating conditions.
 
The Deceleration Fuel Cut Off (DFCO) test is performed to evaluate the Combustion Quality (CQ) signal pulse width if it is below a predetermined value, the value it is expected to be during DFCO conditions. If the CQ signal pulse width is above the predetermined threshold, the fail counter will be incremented. If the failure counter exceeds the calibration, then the test is complete and a failure will be reported.
The Power Enrichment (PE) test is performed to evaluate the Combustion Quality (CQ) signal pulse width if it is below a predetermined value, the value it is expected to be during PE conditions. If the CQ signal pulse width is above the predetermined threshold, the fail counter will be incremented. If the failure counter exceeds the calibration, then the test is complete and a failure will be reported.
The Combustion Quality (CQ) test is performed to check if inappropriate (CQ) signal status were detected. If missing CQ pulses or multiple CQ pulses or CQ pulse width calculation errors were detected, the fail counter will be incremented. If the failure counter exceeds the calibration, then the test is complete and a failure will be reported.
Conditions for setting the DTC
 
Ignition voltage is between 10 volt and 16 volts .
MAP sensor signal is between 26kPa and 100 kPa .
Fuel level is more than 10% .
Engine speed is between 650 rpm and 6500 rpm .
No Crank DTCs set.
No System voltage DTCs set.
Action Taken When the DTC Sets
 
The PCM will illuminate the malfunction indicator lamp (MIL) the first time the fault is detected.
The PCM calculates an air flow value based on Idle air Control valve position, throttle position, RPM and barometric pressure.
The PCM will store condition which were present when the DTC was set as Freeze Frame and in the Failure Records data.
Conditions for Clearing the MIL/DTC
 
The PCM will turn the MIL "OFF " on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
A history DTC P1310 will clear after 40 consecutive trip cycle during which the warm up cycles have occurred without a fault.
DTC P1310 can be cleared using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed.
Diagnostic Aids
An intermittent may be caused by the following:
 
Poor connections.
Mis routed harness.
Rubbed through wire insulation.
Broken wire inside the insulation. Check for the following conditions:
Poor connection at PCM - Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
Damaged harness - Inspect the wiring harness for damage. If the harness appears to be OK, observe the moving connectors and wiring harnesses related to the sensor.
A change in the display will indicate the location of the fault. If DTC P1310 cannot be duplicated, the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set.
 
If it is determined that the DTC occurs intermittently, performing the DTC P1310 Diagnostic Chart may isolate the cause of the fault.

#9 of 25 starter/torsion bars by jeremylo

Nov 09, 2007 (12:48 am)

I was trying to remove the starter on my 99 trooper, and I started to loosen the adjustment bolt on the torsion bar. How do I get it back to normal so I don't mess anything up? "> :

#10 of 25 99 starter by atfdmike

Nov 09, 2007 (7:20 am)

I have only changed starter on 3.2 engine, but I have never heard of anyone having to remove or loosen torsion bar. Regardless, Generally you have to count the number of turns on the bolt, and even then you reinstall and then measure the height from the ground to the frame on both sides. I have read that 4 complete revolutions equals one inch of travel upward.
Good luck
PS. Do a forum search and I am sure you can find someone else who has changed a starter on your model.

#11 of 25 money pit? by francis4

Nov 18, 2007 (8:16 pm)

i recently purchased a 94 isuzu trooper s, it has 133000 miles on it.i paid $1800 for it. i took it to the mechanic and he found some problems with it, he said the intake gasket has a small leak and the oil pan gasket has a small leak he flushed the transmission fluid, power steering fluid, did a front end alignment, replaced fuel filter,and cleaned fuel injector. and replaced the air filter. it ran about $460. not sure if it was worth it or if i got taken for a ride. any thoughts? also it runs a little rough at idle and when i go to take off it hesitates a little then goes. not sure if i should replace the spark plugs or if its the gasket leak causing this problem.

Hi, I have a 94 too, with DOHC. Intake gasket leaks are very common for these motors, usually just have to replace with new one time and that is it. The hesitation and rough idle are most common symptoms of gasket leak.
This engine requires a timing belt change every 60,000 miles, and you can find lots of info on that with a forum search. It is a non interference motor, which means it should not be harmed if the belt does break, but who wants to find out the hard way? I would say you could try the spark plugs first as they are easy to do with right tools and least expensive option. The intake gasket replacement is considerably more time and effort.....4 to 5 hours plus cost of gaskets. The intake is a two or three piece, depending on engine. SOHC is easier to do but still time consuming.
Hope this helps, good luck.

#13 of 25 4 wheel drive warning light by jalder

Dec 02, 2007 (7:14 pm)

It finally snowed, and when I engaged 4wd, the warning light came on. We have had a small, slow leak front the front differential. Is this the likely cause of the warning light, how difficult is it to at least top up the differential, and any hints or special tools?
 
Thanks
Jim
