Update/Need upgrade/high mileage recommendations

Took off my fender liners/steps to see what it looked like slimmed down, planning on blacking them out w/ raptor-liner + getting all new oe clips





Freshly swapped Steering rack (A1 cardone)+ new nylon bushings, pump (drivestar), reservoir, new hoses
(Still have old rack to possibly revive/sell on the low/keep as backup)

Swapped Tie rods, Lower ball joints, sway bar links/bushings/brackets (all OEM)

Also filled in clip-holes/removed emblems/touched up paint














Old pump/hoses were covered






Planning on:
-blacking out grill/rims/bumpers/steps/door ding trim w/ raptor liner (unless anyone has a better recommendation) + bed after sanding out the all rust.
-Still need to swap lower control arm bushings + upgrade shocks/springs that I’ll create a separate thread for
-swapping radiator (just started leaking from bottom corner) thinking Oem, maybe aluminum

Check engine light is on for O-2 sensors

besides that I’m swapping plugs/filters/oil if anyone has any cleaning recommendations for engine/trans/etc. truck has 340,xxx Miles so any maintenance advice is highly appreciated.

 

Timing belt and water pump would be on the highway priority unless it’s been done

 

Both done

 

The front and rear o2 sensors, (only buy DENSO or OEM)
They can make the ol engine run a lot better.

past that you’ve got a lot of things covered. Slowly change the trans fluid, I would t recommend flushing it.
Brake fluid, etc..

 

Check the condition of the transmission oil at the drain plug. The dip stick is only for level check. That's also where you fill the transmission oil from. Your options are fill and drain or flush. You can use 3/8 ID transmission hoses. I think oem might had been 11/32. If you live somewhere warm, bypass the transmission lines to the radiator to avoid pink milk shake. Your down south so your park brake might still be in good condition. But its worth checking and adjusting to prevent brake drag. Might as well check on how drums/shoes and play on the rear wheel bearings. Do not drain the gear oil unless you can open up the fill ports.

 

Once you are mechanically sound, gloat in the fact that you don't have missing clearcoat.

 

So 4 total, upstream & downstream correct?
& do you know if they’re interchangeable b/w front & rear at all?

 

Fronts technically could inter change to each other. Same with rears. But rear is narrow band. Front is wide band.

best to just get the 4 proper sensors. They’re wire lengths are what would be different
