Isuzu Trooper

    One essential item offroad is a 2x2 piece of 3/4" plywood...just for the reason you said, something level and flat to put the jack on, and it disperses the weight so it won't sink in soft ground (it will sink by itself in soft asphalt).

    I use a rubbermaid container from target. I usually have a first aid kit, flashlight, portable shovel, fix-a-flat, gloves, duct tape, raincoat, etc.. This is my standard offroad box, but I usually just leave it in back with a blanket and plywood square.

    Don't forget about Isuzu Roadside Assistance, or AAA for flat changes.

    Thanks for the heads up on the footrests. Do you have the 800 number that I cound call for the ski rack?

    Boxtrooper, I am not sure what it was that cut my tire. I saw it on the road only seconds before hitting it. It appeared to be some kind of metal object--perhaps a pair of long pliars. My front wheel hit it and then it hit the rear tire puncturing it. It was the first such occurrence in over 35 years of driving. Luckily, there was space to pull over on the shoulder. I can be thankful this did not occur in heavy traffic.
  • So, Wildbuc, how did the Troop handle with a blowout?

    Thanks for the answers to my questions. I can't believe that there isn't another way to turn on the interior lights. That is a very strange omission.

    Regarding the intake noise, what I hear is not fan or transmission noise. It just sounds like air being sucked in through the intake. Think of Darth Vader inhaling continuously. :) I only really notice it when accelerating from a stop or driving slowly in 1st gear.

    it is a good thing you weren't in an might have flipped and exploded into flames! Just kidding, seriously though, I am curious to find out if there was any handling issues too?

    What year is your Trooper? I have an 02 and thought that there was not a roof bar or rail system for this year. If you do have an 02, I'd be interested to know how you got something to work.
  • paisanpaisan Posts: 21,181
    Every Trooper from '92->'02 has the same roof. Stock up til '98 had a roof option so I bet there are ones to fit the '98->02

  • I had posted a week or so ago about the outside temp surging while stopped at a light. Someone suggested movinng the tempsensor, which is located behind the grill to an area that would get more airflow. Well, I did it (kinda), and it worked (kinda) - let me explain...

    The wires on the sensor are too short to really move anywhere. So what I did is pulled the sensor out of the mounting bracket and turned it around so that it wasn't blocked by the mounting bracket from circulating air. (if you remove your grill and take a look you will see what I mean.

    the results...
    the temp still surges at a stand still but it seems to surge more slowly and recover more quickly. If I get courageous, I might splice in additional wire so that I can move the sensor to a more ideal location.

    I was traveling about 65 mph when the blowout occurred on the left rear tire. Upon hearing the sound, I immediately applied the breaks and made a smooth controlled stop. There was no problem whatsoever in controlling the vehicle. The Trooper did not yaw or pitch in any way.

    I was concerned that my wheel rim would be bent, but later found this was not the case. The wheel was as round as could be. I was quick to get off the road, however.
  • The 92-02 Trooper roofs have a black plastic covered stainless steel trim in the rain gutter. There are three places on each side with two 6mm threaded holes each. The holes are under paint and under tape. The front set is above the front windows. The rear set is above the rear windows and the middle set is midway between them. The mounding is snapped down and can be removed by carefully evenly pulling up. The mounding end caps break easy, but you cannot see them from standing next to the Trooper unless you are 6'5" and look for them.

    I suspect that these holes are part of the factory process for robots carrying the unfitted body around for welding and dunking in treatement tanks etc.. sells their own made bracket for their own made expedition roof rack. The brackets can be had alone for $39 or so they are part number T100. I do not want a full time expedition roof rack (parachute) on my roof, so I bought just the brackets. There is a very nice expedition roof rack from ECB find it from Paison's web site.

    T100 brackets and three Thule 1.25" x 7/8" x 50" crossbars make up the rack I have now. Each crossbar was drilled half way through using a carbide bit starting with a very small size and going through 3 more sizes up to 5/16" to make a nice round hole in one side of the Thule bar near each end. The Thule bars being only 50" is ideal because the T100 brackets are near enough to the ends of the Thule bars to hold a nut on the inside of the bar with a needle nose pliers. The finished roof rack only shows the head of the bolt onder the T100 bracket and the Thule crossbar caps fit perfectly. The look is clean.

    I am contemplating changing the roof rack system to allow moveable crossbars by using the Thule 415 crossbars to OEM roof rack brackets. Thule claims these are sturdy and I went to REI to measure them. They can clamp to bars from about 3/4" x 3/4" to 40mm x 40mm. The 415 are decently strong, enough to hold anything I would put on the roof. "Only a real Thule would put that much stuff on the roof."

    Here is what I will do:

    Option 1.) Thule cross bars 78" mounted front to back by drilling the T100 7/16 mounting hole out to 1/2" and get stainless square nuts to slide inside the Thule bars then bolt down as before.

    Option2.) Use either aluminum or stainless strut channel and their particular mounting arangements.

    Option 3.) Use two on each side of stainless 3/4" x 3/4" square tube because it had rounded corners and will fill up the T100 mounting surface. Between the two 3/4"x3/4" bars at each T100 bracket bolt into both bars horizontally a solid piece of stainless with a tapped 7/16" hole in the center and bolt these on. This would provide a boltable slot all the way down the bars for easy homemade expediton rack or whatever I would want to bolt up there. The Thule 415 brackets would clamp nicely to the resulting 3/4" x 2" parallel bars and it would be quite strong.

    Option 3a.) Same thing, but pay to make custom stainless brackets for bolting down the 3/4"x3/4" bars next to each other. Would anyone be interested in buying such custom brackets for bolting down side by side two 3/4"x3/4" square stainless bars with a maximum dimension of 2.25"x2.25"x3x4" such that they could be used one on top of each T100 bracket and also be used opposite each other to clamp to the 3/4"x3/4" bars away from the T100 brackets?

    Thank You

    That noise you describe is not uncommon. I hear it on my 99' Trooper as well, but only on cool mornings when 1st starting up. It won't do it later in the day if the outside air temp is quite warm. Don't really know the reason for this, sorta strange. In the morning it seems to disappear once the engine warms up good. I don't notice it after a few minutes, if say I stop at a stop light or sign and ease away from it. The noise isn't there. It may be some kind of designed air bypass or something to help the engine be efficient at cooler temperatures. Maybe the air pump doing its thing to keep NOX gasses down.

    When my intake manifold gasket was leaking I could clearly hear a hissing noise from the engine with the hood up. Might be worth a look...
  • bluedevilsbluedevils Posts: 2,554
    Where exactly do you position the jack when changing a front or rear Trooper tire? I've been lazy and never read up on this in the owners manual.
  • kevtomkevtom Posts: 11
    Very interesting. I knew the holes were there but whenever I have looked for rails from either Isuzu, Thule, or Yakima I did not find any to fit. Isuzu only sales the ski mount, Thule and Yakima only had mounts that clipped in the door (which I don't want). Thule now lists a product called a Top Track that permanently mounts to the roof but don't know if it will fit the pre-drilled holes. I did not know, as you and Paisan pointed out, that the 92-02 had the same roof.

    You mention OEM roof rack brackets. Is that from Thule? So following your suggestions above, I'll be able to have a system to mount a gear basket or even a canoe?? Excuse my amazement but I've had my Trooper since July and have had NO success in finding roof options.

  • paisanpaisan Posts: 21,181
    I use the rear axle near where the shocks mount for jacking the rear and the lower control arm for jacking the front. Not sure if they are the "proper" places to jack it but that works for me. I also carry a small hydrolic floor jack which is easier to jack with than the stocker. Since I've gotten the side rails welded to the frame, I think I'll use them to jack from now on as well.

    Roof bars aren't easy to find but they are out there. I bet if we could figure out the part # of the '92-98 Roof rack you could order it from Isuzu parts.

  • sbcookesbcooke Posts: 2,297
    For the front there are actually 3" circular imprints on the frame about 2' behind the front wheels. It seems like a weird place to jack from, but I believe that is the "official" spot.
  • paisanpaisan Posts: 21,181
    Doesn't allow my OEM jack to lift from the frame :( I never actually looked in the book for the official jack points.

  • sdc2sdc2 Posts: 780
    One of the "official" jacking points is actually the front skidplate, according to the manual. I tried it once, and bent the skidplate. So I don't use that one anymore...
  • I did more measure and calculate. The pair of 3/4" square bars with 1/2 inch between for the 7/16 bolt will make the width of the twin bar assembly 2 inches. The Thule brackets that clamp to OEM roof racks have a flat bottom of 40mm = 1.57 inches. So I want it a little narrower.

    A 1/2 X 1 inch stainless .065 tube is .37 lb. per foot. Twin bars per side 6.5 feet long needs 26 feet or a total added weight on top of 26*.37 9.62 lb. Twin solid 6063-T6 aluminum bars 1/2 x 1 would add about 15.5 lb. up on top. Or about the same as one 78" Thule bar front to back on each side.

    I have thought of a less expensive way to make the brackets to bolt it down too. Use 3/16 thick stainless 316 sheet stock cut in a 2.5 inch disc shape using put a 7/16 hole in the center and fold the edges down such that a 1.5 inch space in between them. Use a low profile bolt head to bolt down directly on the Overlander brackets. I have a request for quote pending for these little parts to be made accurately in a machine shop. The diameter of the disc bracket would cause side bent down about 1/2 inch so one of the disc bracket could go over and one could go under the twin bars to securely clamp anything. I specified additional holes 1/5 inches apart centered on the 7/16 hole and lined up with the gap between the twin bars. These extra holes would allow mounting Thule cross bars direct to the twin bars without need of buying the Thule OEM brackets using a 1.5 inch square u-bolt. The Thule bars are 1.25 wide and the u-bolt would be a close fit. Leave the u-bolt attached to the Thule Cross bars when removing and install quickly with the center 7/16 bolt and a cam nut like bicycle seat posts use.
