Hello All,
I have a 97 T100 4x4 with the 3.4L V6. My truck has 181k miles. Other than regular serivce (oil, coolant, timing belt ,ect.) this truck has never had any other service. I hate to sound ignorant, but is there anything else I need to look at. The truck runs great. Thanks in advance, Randy

The front/rear differentials should have had fluid changes as well. Same with the transmission auto or stick. The auto trans would also require the filter changed out. I am new to the 4x4 scene, so I am guessing the transfer case would also require regular fluid changes like the diffs.

I too have the same truck and love it!!! I have about 125k miles on it with no major problems, exept for the low gas mileage 14-16. The only major thing I did was replaced the timing belt. It didnt break but was advise after 60k (I think 60k) The t100 kicks butt.

Plugs? I've replaced the plugs several times. I've read where NGK is the best for Toyota. The owners manual recommends a double electrode plug. The tip of NGKs' grounding electrode is curved to match the diameter of the center electrode. I suspect this is to maximize the surface that is at the proper gap and maximize the spark.
