Does the 1999 Trooper have the Locking Differential or the Limited Slip Differential?After reading post #3058 at the GMC Envoy site it mentions the G80 Differential and I believe that is the code number for the Isuzu Differential being used in my truck. I believe I would perfer the locking over the limited slip. At the GMC site Eaton has a nice explanation on how each Diff operates. Happy New Year

I don't believe the current body style Trooper ever had a locking rear diff. They are all Limited Slip. The only locking differential that really came stock were the older Mitsubishi Montero's.
#2829 of 11965 I like that Hyundai SUV!!!

They should import that thing. I can't believe how the SUV market keeps going. I think Lexus is getting another SUV for a total of three. Lincoln is going to get a another SUV.

The reason you didn't notice this with other vehicles is that they generally don't give you the oil specs for a new engine. Normally, they specify capacity with and without a filter change.
Clearly, .6 qt. is staying in there somewhere. There is no other explanation possible.

The previous generation Land Cruiser also had locking diffs. In fact, you could lock the front, center, and rear diffs for an even torque split to all 4 wheels.

Yep the Envoy can have the locking rear (which won't help you when the angle of departure lifts both rear wheels off the ground) most 99 and all 00->02 Troopers have rear LSD. The 01->02 Troopers have the Corp 12 bolt rear while the 92->00 have Dana 44s, you can get numerous lockers for the Dana 44s. You can also get an ARB locker for the front of the 92->02 which is the Isuzu 10-bolt diffy. Also you can get the Isuzu Impulse rear LSD gears and put them in the front of the Troopers 92->02 as well giving you a front and rear LSD.

01->02 TOD Troopers have a modified rear Isuzu Corp 12 bolt differential. 92->02 non TOD have Isuzu Corp 12 bolt diff(some LSD and some not). ARB makes a locker for the Isuzu Corp. 12 bolt. I believe the numbering for it is RD44 but this is not for a Dana 44. The rear LSD for an Impulse or for a first generation Trooper (either one or two) should be an Isuzu Corp. 10 bolt which will fit in the front of the second generation Trooper. I believe this is correct, but feel free to correct me. One question. If Isuzu ever had a Dana 44 in the rear how would one identify this and what models was it placed in (1st or 2nd Generation...S,LS,Limited...years)?

According to a knowledgeable source at planet isuzu 98->00 all Troopers used a Dana44 rear end. I may have been mistaken on the 92-98 models. I believe pre 92 had dana 44s in the rear and 98->00 have Dana 44s as well.

A buddy of mine has a '98 Acura badged Trooper with 32K on it. For no apparent reason, the transmission failed catastrophically. The Acura dealer is replacing it under warranty.
Is this a common occurence (losing a trans I mean, not having it replaced under warranty)?
I don't drive my 98 much, and I think I will probably get to 5 years long before I get to 50,000 miles. I guess I'm worrying that I should get that extended warranty...

The tranny in the Troopers, rodeos etc. is known to be a long long lasting unit. They are one of the strong points of these vehicles. I would not worry about it at all. This is about the 3rd or 4th tranny out of maybe 300-500 owners I know of.
