If you hear strange sounds from the back leave it! Rear axle is the biggest problem of the 5.9 and all grands.

Try to drive it on the highway for about 30 minutes before you buy it. When you slow down, try to make sharp turns on the pavement. If it is buckling and turning rough, you have a bad viscious coupler (see the articles about swapping a t-cases). Plan on $1500 to fix the NV249, or maybe a little less to swap to a 242 and have the 2wd option.

I love mine. It has great jump off the line and great sounding stock exhaust. There is a porblem wiht the govenor and shift timing that I have i dont know if anyone else does. It cuts off power right before I shift on high rpms so it bucks but i havent heard of it much before. Overall i love mine.

Premium only unless you want to flash the computer to run on lower octane.
