+ 1 on the timing belt. Just had mine replaced along with thermostat and water pump at 105,000. Well worth the investment. BTW... the dealer's price was $200.00 more than my local guy down the street. Had the dealer do the work. All seems well. Watch the two rings next to the mesh exhaust piece underneath, they rust off and rattle. I just cut them off and all is well. So far, and being the original owner, this truck has suited me well for nine years!!
