Recently purchased a 96 f150 4.9 liter. 155,000 miles. Truck runsgood but maint. history is unknown. I have completed or am in the process of the following: Oil and filter change Manual 5 speed fluid change maxlife syn. ATF Rear end 85/90 and limited slip additive change Antifreeze drain/refill (scared of flush, OLD antifreeze and grime) New radiator cap New thermostat/gasket Front brake pads rear brake shoes New pcv Motorcraft plugs, cap & rotor and wires Air filter New fuel pump (sending unit was bad) Fuel neck (original was punctured/leaking) Fuel filter 4 new monroe shocks New drive belt Refurbished: Ac compressor/drier/oraface tube, flushed and recharged system. Windshield washer pump replaced Door hinge repair kits for sagging doors New side mirrors for mismatched mirrors Anyway i need a salvaged bench seat, but other than the above what would aid reliability\longevity?

Brake fluid flush. If the clutch actuation is hydraulic, include the clutch system in the flush. I had a 1986 F250 with the 4.9. Loved the engine. Very reliable and torquey. Super easy to work on. The fibre timing gear went out on me twice. I replaced it with an aluminium gear and had no more problems.

Id love to put in metallic timing gears. How hard are they to install and how much noisier are they?

Tires are new, but need front alignment asap or fronts will be ruined. Hoses appear/feel fine.

Side note: Im sure some would mock fixing up a beater, but i say cheap taxes, cheap ins, and title in hand cant be beat. Plus i love the 4.9 motor even if its thirsty. This is not to be a commuter vehicle anyway. I picked this truck up due to the motors reputation and the fact that its totally stripped down, crank windows, ect mean less to go wrong.

Watch for the rubber plugs on top of the tranny. They shrink/rot and out spills your tranny fluid causing your tranny to run dry, a common problem with these. There is a way to replace them with brass plugs, look on the internet. My 1989 F-150 with your engine tranny combo ran fine on ATF. My 2002 F-150 with the 4.6 V-8 and the same manual shifted horribly with ATF. Finally went with a manual tranny fluid with the same approximate viscosity as the ATF and the shifting is so much better. No more crunching and grinding like it did with the ATF in anything but cold temps. Whimsey

Drive belt replaced with heavy duty dayco belt. Hoses felt fine except for pcv hose that disentegrated in hand. It was replaced with purpose made generic pcv hose. Ford no longer makes the specific pcv hose!

Rubber plugs on top? We drained out the drain hole, closed that up and filled from the cabin, you can do this by lifting up the shift boot and unscrewing. Also replaced shift "spring" around shifter which had deteriorated.

If the front end is out of alignment, you need to check for play in the suspension and steering parts and see why it's out of alignment.

I fixed my beater commuter car. Nothing wrong with that. I love how it less than $40to fill it w gas, insurance is cheap, registration is nothing, and the vehicle has a good reputation of lasting. Post pics of this find

It wasn't hard at all to put in the aluminium gear. My machinist warned me of excessive noise(whine) but I did not hear any whine at all from the alumnium gear. Does the '96 have the twin I-beam front suspension with king pins like my '86 did or did they switch over to ball joints by then? If king pins they need to be religiously greased at regular intervals for long life.

Would steel gears be better than aluminum? Also i dont believe there are ball joints there. Friend is an ase mechanic and sais front suspension looked good, i will bring up greasing. I want to grease u joints also.

Aluminium was what was available, so that is what I used. Perhaps aluminium is preferred in that application because if any issues arise the aluminium will sacrifice itself and save the steel crank gear.

If your truck has any slop in the shifter at all put a shifter bushing kit in it. Cost like $14 and mine shifts like a new one now. Other than that I think you're on the right track. I've had no problems with my truck and I drive it every day and have no intentions of ever getting rid of it.
