Ok so i have a 98 4runner 2.7L 2WD with almost 160k. so far ive got new shocks and new starter. i want this thing to last forever so is there any preventative maintenance i can do to keep my runner in good shape?
thanks

 

auto tranny? get the radiator replaced....read up on strawberry milkshake.

Timing belt ( or is the 4 cylinder a chain?) and water pump done on time?

just keep paging back-reset the default at bottom of page away from last 30 days...

 

Above is good, plus....

obviously all fluids, including trans, diffs, coolant (& thermostat/WP), TC, brake fluid and power steering. Plugs and plug wires (if original--will say Sumitomo 1998). Inspect brakes (pads, shoes, e-brake operation). Grease driveline. Air filter. Test fan clutch. Clean MAF & TB. Check steering rack bushings and all suspension components--ball joints, sway bar bushings/links, tie rod ends, etc.

You could do O2 sensors if believed to be old or engine not running 100%, or just wait for them to throw codes.
