99 Ranger T Case Fluid Question

[lil_Blue_Ford]

I get a headache trying to read this thread... lay off the sugar man, lol

I've found that with filling the rear axle, sometimes it will start to run out but if you leave it sit a min it'll level itself off (gear oil is a bit thick) and you can finish filling. I usually try to put mine on a slight backward slope so that it's just a hair overfilled (which is how it comes from the factory).

If you have a limited slip rear axle, you should have friction modifier in with the gear oil, unless you used a good grade of synthetic (even then I might consider using it though).

Going to smaller tires will change your speedometer and odometer readings, thus you may percieve a difference, but it will be relatively minimal if you figure out the difference. If you're looking for great fuel economy, a truck just isn't it. I'd love to have something that got really great fuel economy, but since I do construction work and run my own business, it's just not practical for me to own a car, so I put big tires on my trucks and try not to cringe at the pump, lol.

I don't remember how much fluid it takes.

Hey on a side note what would you think would be the skinnyiest tire i can get away with?? I have the XLT Ext Cab and sport package, I have the same tie as you factorily. Would going with a norrower 215 75/16 or some thing be able to help with the mediocre fuel economy?? Many Thanks

5.0 US pints or 2.5 litres.

Straight outta the ford manual.

If you're going for fuel mileage you've got the wrong truck! The 99 3.0 I had got 14 mpg's. If you want a smaller tire go back to the stock size.

Hi Again and Thanks for your input. The 245-75/16 came stock on this one, It is the "Sport Package" in the door jam states factory 16 in tires, for what its worth. I am getting in the 18 mpg range thought that wasnt real good, I am guessing that is about what these get huh? robably will come up with a question or two more, So Thanks All, Enjoy the ride.

I would love to get 18. I'm getting 14 in my new 4.0 Ranger. The Sport package doesn't have anything to do with what you're refering too though, just different options.

Ford likes to put the largest axle they offer on a given vehicle on if it comes with a tow package, regardless of the engine. And once upon a time you could be a 3.0 ranger with a factory tow package. I've seen 10.5's in 4.2L F-150s just because they had tow packs. As for fluid, use T-case fluid in the t-case (its AFT with the friction modifier to ease shifting) and if you have a locking rear ALWAYS use it. If you don't your diff clutches will wear out much faster as the friction modifier allows them to slip against each other when you turn.

The transfercase will use Mercon V ATF. No friction modifier needed in the transfercase.

My ranger had the wiring for a trailer and a trans cooler but no hitch with a 7.5 rear axle. Ford makes me wonder sometimes...

My 93 4.0 4x4 gets about 17-19 with a bad MAF. The only trucks I have heard of doing that bad without mods had 4.11's from the factory. I htought it was only 99 and up, but coulda been sooner.


EDIT:: Mines also a 5 spd by the way. Its the autos with 4.11's Ive heard doing so bad.
