    I bought replacement pads for my '00 Trooper LS at the local dealer. He printed out a diagram that show where all the parts go....many more shims, etc. than I had to deal with on the '00 Jeep GC we had. I have not put them on yet, so I can't really tell you how difficult the job is yet.
  • I have owned "Lulu" since June 11, 1988 and she died last week - Oct. 14, 2005 with 240K miles. I have been the only owner and she has been a "real trooper" for 17 1/2 years. According to her doctor "Dr. Weaver" she has a cracked head and he has advised me not to try and resuscitate her this time. I don't know alot of details and the mechanical terms to use but I am hoping if someone can tell me if I should heed the advice of my mechanic and let her go or have her repaired. If repaired what can I expect as far a performance, etc. I had let someone use her the last couple of months and they failed to have the oil level checked and she was 2000 miles past her oil change. I had always taken her for her oil change on time (3000 miles) and taken wonderful care of her. I feel really bad that this has happened and I just can't seem to make myself accept that she cannot be repaired. I am sure some are truly laughing out loud at this crazy person but I am for real. If more details are needed I can ask the mechanic. Thanks for any suggestions.
  • It was a snap! Did all four corners and rotated the tires in a hour. Two bolts hole the calipers on (17mm front,14mm rear). The lower bolt comes all the way out and the top unscrews but is retained, then the caliper just swings up exposing the pads. Rotar surfaces were nice and smooth so I did have them turned (everyone has their own opinions on to turn or not to turn). Replaced the pads, pushed the piston back in slowly with a big C clamp and put it all back together.
  • 2000 miles past an oil change did not cause her to die....UNLESS that meant she ran out of oil. 3000 miles is a distance that oil sellers have advertised for years to get you to buy oil more frequently but, I bet if you look at the owners manual is probably says 5000 or even 7500 depending on your driving conditions. Get away from conventional oils and use synthetics. Yes, the initila sticker shock of $5+ a quart is a bit much for some but, you on't have to change it as often and it is a superior lubrication plus, you are not using more petroleum products. As fixing her, anything is possible.....it just depends on how much she means to you, and how much are you willing to invest. I think though that saying she died because she was over mileage is like saying the 99 year old man dies becasue he smoked....No, he died because he was old! Sorry for your loss anyway....I love my trooper too but, mine is a young Philly: )
  • Hi, thanks for your reply. I have this vehicle ('99 TOD Trooper) in my mechanic's shop now (he's an Independent, not an Isuzu dealer shop). I've told him about this part you've identified (Transmission Range/Mode Switch) and he's contacted 2 local Isuzu dealers here in Long Beach, CA. Neither of them knows what he's talking about! Is this the technical name of the part? - You mention "St. Charles Isuzu" - do you have contact info for them? Perhaps he can order the part from them directly. Thanks again.

    Just search for St Charles Isuzu in your Browser and you will find it. Edmunds policies prevents me from typing the actual web address, if you search for my other posts on this board, just search for Transmission Mode Switch and I think one of the post I posted the web address, not a big deal you will get on the internet, St charles Isuzu is the best Authorized dealer for Genuine parts with Whole sale prices. The dealerships usually refer them as Transmission Mode Switch, Transmission Range Switch also Transmission inhibitor Switch, but the most common name I have heard of is Transmission Mode Switch. Go to the nearest Auto Zone and look at the Haynes repair manual in the Transmission section and you will see a picture of the Transmission Mode Switch. What this Switch does is, when you change the gear, there is a lever inside this switch which moves and tells the position of the gear to the Transmission computer. The switch is installed on the shift rod of the transmission, when you change the gear, the transmission shift rod moves clockwise or anti-clockwise and hence the lever inside this switch. This switch is installed on the side of the Transmission, it is on the Driver side in Rodeo (Auto), this switch looks like expanded 'V' with a wire harness connected to it. Call any Isuzu dealer and ask for Transmission Mode/Range Switch, it costs around $142 whole sale, $180-$200 retail, you may want to go to the Dealer parts shop in person and check it out to see how it looks.

    hope this helps.
  • :P Havent had anyone help me out with this yet, so heres a shot... I got a clunk, when I take off at the light. And Ive got a clink, or a clunk, when I put her in gear.
    I have a 2001 trooper with 83000, Took care of the oil consumption, with engine flushes, and synthetic. Changed the plugs out with denso's cause it came with champions. Changed the timing belt. Replaced shocks. Did the tire Bal/Rot. Also, put a new IMG and plenum on her. She surged at a toll booth. Any suggestions? SOMEONE PLEASE HELP!
  • bahmedbahmed Posts: 66
    If it is slipping the gear like from 1st to 3rd while accelarating from Stop and if jumps from 3rd to 1st when it comes to stop, it is more than likely the old Transmission oil or low transmission oil, if that is o.k, then it is the common Transmission Mode/Range Switch. If your talking about the something else, then it could be the Slip Yolk in the Drive Shaft, from the mileage of 83000 it could be either the Transmission Mode/Range Switch or the Transmission Gear Shaft Slip Yolk greased have dried out. If it is the Transmission Range/Mode Switch, change it is like $142 for the part, if it is the grease in the Slip Yolk, you need it get it regreased.

    Hope this helps.

    I finally got around to replacing my brake pad ('00 Trooper LS 2/wd) Saturday. It took me a couple of hours since I used the standard jack and jack-stand one wheel at a time. No problems....just as you described. Much easier that the old '00 Jeep GCL we had a couple of years ago. I had purchased the pads from the local Isuzu dealership maybe 6 weeks ago.

    My only disappointment is that the original pads still had at least 60% of the original pad material, except the inside rear pads were probably down to 30%. So, I probably could have gone another 50,000 miles on the front and maybe another 20-30,000 on the rear. But I figured with 91,000 miles they should be ready. Glad to have it done and won't have to worry about it again.
  • I have a 1990 isuzu trooper v6 auto . While i was driving it just shut down and stalled . I have checked for spark and fuel and both are fine . can anyone suggest what might be the problem? Any help would be appreciated.
    Thanks
  • I'm trying to replace the water pump in my 88 Isuzu pickup (2.3 liter engine). I'm having problem with removing the timing belt cover. can anyone help me?
  • I have had similar experience; check for loose or broken engine mounts, especially in the rear. I also had a transmission rebuilt once and the supporting cross member had a rubber pad/bumper on it. They broke it during the replacement of the transmission and I had a knocking ever since, especially when accelerating from a dead stop.

    :( I bought my 1996 trooper on 78k miles this summer.
    When I purchased it, I brought it to the ISUZU dealer.
    They told me this vehicle is in good shape, maybe never off-road before. Howerver, there is something flaws:
    1. the power steering pump leaking;
    2. engine oil leaking;
    3. need to change the CV-boot;
    4. frant bearing loosing.

    For prob 1: I rebuilt the power steering pump and it stopped leaking. The power steering system works well, but sames the power steering wheel doesn't stay stable at the center point. A little loosing.

    For prob 2:I changed the engine oil cooler gasket, it stopped leaking.

    For prob 3: I changed all the four CV-boots, and no whimper
    while I make a turn.

    For prob 4: I paid 265$ to fix it.

    But after I changed CV-boots, there are some new problem come out.
    1. Sometimes "buzz" when I hit the accelerator, after a little while it goes away. This comes out especiallly after I turn right.
    2. Sometimes the brake shakes, especiallly after I turn on the engine and start to shift transmission.

    Some tech. told me the "buzz" comes from the muffler, something loosing inside the muffler. About the brake, may need a bleeding. (when I pull out the balljoint to take off the cv boot, the arms flipped out the brake pad assembly. Maybe this cause the air into the vacuum pipe.)
  • I own a 99 trooper with 92K miles and bought it with 74k and I am unsure of previous maintenance. It was an affordable vehicle at purchase and has been affordable to maintain so far (only oil changes). I am trying to decide if I should keep the trooper for the long haul and invest in it or sell it in a year.

    I was thinking of doing some maintenance to try to keep the trooper going for awhile, but I am concerned about the transmission reliability.

    I was considering a transmission fluid change or flush among other things

    Two local transmission shops with good reputations said not to touch the transmission fluid if I am unsure of previous maintenance as the newer additives would ruin my transmission if it had not been changed every 30,000. They said if its not broke don't fix it at this point. My local dealer said to give it a flush, but they have an average reputation at best.

    One person went so far as to tell me I would be lucky to see anything over 120K, and very, very, very lucky to hit 150K on this particular GM transmission.

    What do you think about the transmission reliability and flush versus leaving it alone.

    Quick question for all. I have a 2000 Rodeo Ls with 87k miles on it. Virtually trouble free from day one. Looking at the Ascender (I like Isuzu's, this would be my 4th one), however have some concerns about the company staying in the states (warranty issues) etc. Also, how are Ascender owners doing with it quality wise. Again, I have had 3 Isuzus (2 troopers and the rodeo) they have all been great. Thanks
  • bahmedbahmed Posts: 66
    Please be aware that the Ascender is not at all a true Isuzu, they are just a rebadged GM TrailBlazer/Envoy. Just compare the inside and outside pictures of a GM TrailBlazer with that of a Isuzu Ascender, you will notice the similarity. Hope this helps, the only benefit you may get is the longer warranty, not sure about the price.
  • GM contracted Isuzu to redesign their S-10 pickups and SUVs, the results are the Chevy TrailBlazer SUV and the Colorado Pickup and their copies sold by the other GM brands. While not entirely an Isuzu design, these are a huge improvement over the S-10 series.
    ..
    So, to me the Colorado and TrailBlazer are just as much re-badged Isuzus as the Isuzus are re-badged GMs. Check out the Isuzu DMax

    2007 Isuzu MU-7 the next trooper?

  • Help! I have a 2000 Trooper, 4WD. Here in Atlanta we are required yearly emissions testing.....mine failed! The printout said EGR, misfire, and all 4 sensors bad. I know about taking the ERG off and cleaning it. Also planning a tune-up and will attempt replacing the sensors myself. But before I start, a few questions:

    1. Where can I get a maintenance manual? Neither Chiltons nor Haynes have yet to print one.

    2. I'm new to Trooper self maintenance. Where is the ERG located. What about the 4 sensors?

    3. Anyone have any suggestions or warnings before I start?

    I appreciate any help anyone can get! Thanks in advance!

    I'm going to dig through the forums here for more ideas, but in the meantime I wanted to ask a question right away regarding Torque on Demand (TOD). Sold my 98 Trooper to parents, who bought it primarily for snowy winter driving. Well, the TOD is on the fritz again - flashing red "CHECK" occasionally and blinking all the time when the 4WD Auto button is pushed in (turned on).

    1. What are the possible root causes of this problem? I seem to recall some sort of faulty 'sensor' but that's it.

    2. How have folks gotten their TOD issues resolved? I'd hate to see my dad drop $500 at the Isuzu dealer, especially since I just sold him this rig a few months ago. But if I was confident they could fix it right the first time for that amount, it might be worth it. We've never visited the Isuzu dealer in his town (Fox Isuzu - Grand Rapids, Michigan) and I have not heard anything about the quality of their service department. He uses a local shop for most/all maintenance/repair work on his vehicles. They are honest, friendly, priced right, and willing to order parts from dealer or elsewhere as needed. But they likely have very little Trooper knowledge. Would it be worth trying to get the problem fixed at this local shop instead of the dealer? It would probably be cheaper if they could fix it there, but I don't know if they could figure out the problem. I have no idea how hard a problem like this is to figure out.

    Thanks in advance for the help.
  • On my 2001 the EGR (exhaust gas recirculation) valve is on top of the engine in plain view near the firewall on the passenger side of center. It is about 2 inches in diameter and 4 or 5 inches tall. The original was black, the replacement was silver. The 2001 EGR valve is a GM part, so you might try and cross reference it to a GM car part number to buy it for less. I had my mechanic change mine, the part cost was between $175 and $200 and the labor was the same, the cleaning out part is the hard time consuming part. The cleaning takes place in the hole where the EGR valve was removed, not so much on the valve itself. I was told the silver one is a better design than the black one.
    ..
    The EGR valve if failed could be helping to cause the missfires especially at low RPM.
    ..
    Fix what you can, maybe have a look at the missfiring spark plugs? Then reset the computer by removing battery power for an hour and then drive a while to fill up some history for the emissions tester to read in when it talks to your ODB2 engine computer.
