Head gasket blew at 140,000. Replaced it and it blew again. Finally replaced block and now have put 8,000 miles on the new motor.
Seats were recovered, A/C compressor replaced.
New tranny and front end.
It took some work, but now "Nissy" is in her prime again. Everything is brand new. This is a very reliable as well as a fun truck. She never lets you down in the mud. I wouldn't ever trade Nissy for another vehicle.
Are you running stock size tires?
