Hi, here is what Isuzu says about your vehicles' timing belt. Generally, it is a good maintenance practice to change the water pump as having to do it if it fails means performing the same work to change the timing belt again. I don't know that they are prone to breaking, but since they extended the service life with this technical service bulletin, It would seem prudent to follow their advice.
1998 Isuzu Truck Trooper LTD V6-3.5L
Vehicle Level Engine, Cooling and Exhaust Engine Timing Belt Technical Service Bulletins Maintenance - Timing Belt/Valve Clearance
Maintenance - Timing Belt/Valve Clearance
MAINTENANCE SCHEDULE INFORMATION: TIMING BELT REPLACEMENT
INTERVAL AND DOHC V6 VALVE ADJUSTMENT SCHEDULE
TIMING BELT REPLACEMENT
1998 Trooper (UX) / Rodeo (UE) / Amigo
In the past, the timing belt replacement for the above affected vehicles has been recommended at every 75,000 mile intervals, regardless of driving condition. It is now recommended that the timing belt replacement interval of the above 1998 Isuzu models follow the same timing belt replacement interval as its 1999 model year successor. The new recommended timing belt replacement interval is 100,000 miles for normal vehicle use, and 75,000 miles for vehicles driven under Severe Driving Conditions.
NOTE :If the vehicle is usually operated under the conditions corresponding to any severe driving conditions given below, it is recommended that maintenance services be performed at the interval listed under Severe Driving Conditions.
^ Towing a trailer, using a camper or car top carrier.
^ Repeated short trips of less than 8 km (5 miles) with outside temperature remaining below freezing.
^ Extensive idling and/or low speed driving for long distances, such as police, taxi or door-to-door delivery use.
^ Operating on dusty, rough, muddy or salt spread roads.
V6 VALVE ADJUSTMENT
1998-2000 VehiCROSS (VX) / Trooper
(UX) / Rodeo (UE) / Amigo (UA) V6 models
with "direct-attack" valvetrain.
For the above affected vehicles, periodic 60,000 mile valve clearance inspections are not required. Adjust if valve noise is evident or a rough idle condition exists.
NOTE :When checking valve clearances, adjustment is required only when the clearance (lash) is out of specification. Be sure to retorque the camshaft bearing cap bolts before checking and adjusting the valve clearance.

I think the first thing would be to rule out the brake pad/shoe condition of your brake system. The ABS system does a self test but it does not sound like rubbing or cause any braking activity on its' own.
It appears that you have rear drum brakes. The rubbing sound could be anything from the backing plate contacting the drum as it revolves to some brake component rubbing on the inside of the drum.
Also, there is a wheel speed sensor that is in very close proximity to the moving drum and if dirt or an object got stuck it could conceivably make noise and affect the ABS system. If the noise goes away when you apply the brakes, it may simply be a shoe or spring rubbing on the drum while the brake is not applied, and should be repaired.
Sometimes powdered iron will build up in tight spots and cause a noise as well. I would suggest you inspect or have the brakes inspected soon. good Luck

I'm looking for a place in Memphis to change my timing belt ('00 Trooper LS). I did check with the local Isuzu/Chevy dealer and was quoted around $850 to replace the timing belt and change the water pump. Has anyone had this done and what did you pay?

Thank you very much, just a bit more info. I had the brakes looked at and they replaced front shoes and blew out rear brakes with air, incase of dust etc. But it still the same sound. It sounds like I am driving over a break /crack in a concrete road . like there is a break every 10 feet and this never ends. Even when I push on the brakes. My check light on the TOD flashes constantly unless I push the 4WD button. Then it goes away. Is it drive shaft, transmission, transfer box, maybe? Just guessing. 1999 trooper. Thanks again.
#3052 of 3299 What to Look For
Jul 02, 2006 (9:04 pm)
I'm sorry if this has been asked before i didn't find anything specific.....but........i'm going to look at a 1996 Trooper tomorrow & was wondering what were the main things to look out for on that model year......it's got 115,000 miles and looks clean from photos. Any help appreciated. i'll post back on how it went.

Well........i did a bit more research here though and had a good idea of what i was getting into .
Anyway i bought it, seemed like a good deal for the price in comparison to what i see selling on ebay.
Truck drove ok, steering a little loose, but that's pretty common from what i've read here.... Some lifter noise , nothing major , can't really here it at idle unless you open the window but i changed the oil today with synthetic 5/30, so we'll see if any noticeable difference.
Had the check engine light come on steady yesterday, went to autozone and got the codes pulled - 3 codes were read, 2 for 02 sensors and 1 for EGR recirc....i had a look at the air filter yesterday morning before it happened , maybe i didn't reseat the cover properly ? In any event i went ahead and replaced the air filter, filled up with Premium, and used the chevron techron cleaner(as well as the oil change). Unhooked the Batt, and Check engine light is gone.
Drove 15 miles, still no Check engine light, touch wood !
Have a low noise towards the rear that occurs at 65-70 mph , i can't tell if it's wind noise at the rear door, spare tire wind noise, or coming from the rear tires (tires are new) or possibly rear axle noise?????? I will get the wife to drive while i hop in the back to investigate !
All the power stuff works, except cruise (any ideas ?) AC is good, wife likes it......All in all, happy with my purchase (but being a natural worrier i'm expecting the thing to blow a head gasket or something any minute now !!!)

It sounds like I am driving over a break /crack in a concrete road . like there is a break every 10 feet and this never ends. Almost like a flat tire sound. Even when I push on the brakes. My check light on the TOD flashes constantly unless I push the 4WD button on. Then it goes away. Is it drive shaft, transmission, transfer box, ASB maybe? Just guessing. 1999 trooper. Thanks again.
#3055 of 3299 98 Rodeo, S 2WD, Any Rear Air Vents Option
Jul 10, 2006 (9:16 am)
I am wondering whether any of the Isuzu Rodeo had any Rear Air Vents, my 98 Rodeo does not have one. I am not sure whether the 2000/2001 model of the Rodeo just before they stopped production had any Rear Air Vents out of the back side of the Center Arm Rest (Console). Is there any off-market upgrade available to add some air to the rear seats, I am thinking can anything be done by using the air coming out of the two small ducts under the front passenger seats.
Appreciate your help.
#3057 of 3299 TOD problem and speed sensors
Jul 12, 2006 (4:30 pm)
The CHECK TOD light blinks and the code says speed sensors. There are 2 sensors but they cost near $350.00 each. How do you test which sensor is defective> Need help or Trooper is a goner. Thanks
