  I was driving about 35 mph on a rural road and I noticed that upon giving some gas the vehicle did not respond at all. then I noticed that all my instrument panel lights were out....everything gone. I applied the brakes and with difficulty in steering (there was no power), I pulled to stop at the side of the road. I then put the vehicle into park and turned the ignition key off, then restarted the vehicle and drove away. this IS the only time this happened (last week).....a complete loss of power. I know isuzu shares parts with gm (e.g. My transmission IS gm). I hope this IS not an example of that gm ignition switch problem.....but certainly has the exact same symptoms of it. but it IS very scary loosing complete power like that. *tr

  I took my 2002 isuzu trooper ltd. To the dealer (fitzgerald dodge isuzu, rockville, maryland, complaining of a growling noise. While it was mis-diagnosed, the dealer indicated that the underplating on the car was suffering from faulty welds, and that if I didn't have it removed it would fall off while I was driving. I had to pay several hundred dollars for this to be performed. I now have no underplating to protect the car. It seems to me this IS a manufacturers defect, and the owner should not be obligated to remove portions of her automobile to correct faulty manufacture, and be subjected to risk of potential death or injury to herself or others on the road. The trooper only has 45,000 miles on it and IS just over 3 years old. *Jb

  Motor will rev up when sitting still at a red light and try to lunge forward. I have even had it go 35 miles an hour without my foot even being on the accelerator. I have had my truck to the dealer 3 times now and they keep saying they can not find anything wrong. unless they can see the vehicle do it they can't fix it. the check engine light does not come on and they say until that happens they don't know what IS wrong. dealer refuses to keep vehicle and drive it until it does it so they can see it. they make it sound like I am making this up. there IS a problem and it needs to be fixed. I do not want to be responsible for a accident that I have no control over. the state police says it IS illegal to drive a unsafe vehicle on the state highways. I owned a brand new vehicle that IS illegal for me to drive on the state highway and isuzu won't do anything about it. I have contacted isuzu corporation as well as been back to the dealership 3 times and it IS still doing it.*ak

Technician should be advised that the maximum pinion shim to be used or stacked behind the pinion is 0.050?, and the minimum pinion shim is 0.020? for an 8.6 axle. The range for available pinion depth shims for the 10.5? axle is 0.006? to 0.024?. When setting the backlash it should be set between 0.003? to 0.005? on a new ring and pinion for any American Axle Manufacturing application. The ring and pinion can be reused or adjusted if the mileage is less than 500 miles, if not used for towing. Technician should be advised that a ?roller coaster? or ?hourglass? pattern on the bearings may be normal up to 10,000 miles and possibly longer. With a mis-machined housing you may get a heel pattern on both sides of the gear teeth at build up can generally be corrected with backlash adjustments. When setting up an 8.6? axle with a 5 cut gear set is to use a 0.035? pinion shim and set backlash to 0.004?. When using the newer 2 cut gear set also use a 0.035? pinion shim and still set backlash to 0.004?. To set the gear pattern use backlash to adjust the pattern heel to toe. Use the pinion shim to adjust the height of the pattern. The proper drive pinion bearing pre-load is from 15 - 30 inch pounds with new bearings. The total torque to turn after the differential case is installed should increase 5 - 10 inch pounds at the pinion. A new pinion nut must be used whenever the old one is removed. The axle shaft end play specification is 0.012? per side and the radial specification is 0.002? - 0.003?. Technician should be advised that synthetic lube can be used in all new American Axle Manufacturing axle assemblies. The new pinion seal for the 8.6? axle assembly is a two piece design.
