i just bought a 99 tacoma with elocker, 3.4, manual, 4x4, with 140,000 miles. My question is what parts should have been replaced? Like o2 cencer..... I was wondering when the struts, timing belt, 02 cencer, rear shocks? If any body can knows when like miles these items should be replaced and any other items should be replaced or inpected.

It wont let me view it.

 

get an OBD II meter and check for any codes.

if no codes, then don't worry about it until you get some

in the meantime, shocks, brakes, belts, fluids is all you should get freshened
