[color:"purple"] WELCOME TO THE BOARD [/color]

Good choice on finding the '91.....I love mine even after 10 years, It'll break my heart when I finally have to give her up.

For an owner's manual and even the full OEM service manual (which I highly recommend) go here:

Some things you might want to do before too long:

Zero-time (pilot-speak) ALL fluids and grease points so that you KNOW their status:

Hub and spindle (front) - Clean, and re-grease including bearings. The AutoHubs are not maintenance free and are known to wear the end of the splined cv spindle. Many people ditch them and get manuals.

Front and Rear differentials - drain and refill 75/80W gear oil

Engine oil - self-explanatory

Transmission fluid - IMPORTANT - if your trannie is manual, this will take (most likely) 30W MOTOR OIL - NOT gear oil as the diffs do.

Coolant flush and replace

Brake fluid flush and replace

Clutch fluid flush and replace

If your doors 'pop' and are hard to close, I've had some success thoroughly cleaning each spring assembly with brake cleaner, getting the spring really clean and then applying a light coat of grease.

Balljoint grease - inspect condition of rubber boots around all ball joints

CV boots, two per side - inspect and replace if necessary (DO NOT put this one off)

The GM 2.8 is a good engine, much betta than the '80's vintage series, but does have some quirks. Do a SEARCH here on '2.8' and you'll get TONS of information on that motor and swap options

Hope this helps as a primer - the old gals are aging rapidly and need a lot of attention.

Check the option code plate on the pass side firewall and the VIN then go here:

http://www.itog.com and then to the ITOG university. You can verify exactly what your Trooper has. If you happen to have the G80 code, your in great shape with the LSD option, IF the LSD isn't worn out.

Cheers,
