Just fill the the rear differential will fuild comes out and your done.
The transmission fluid capacity for your truck, automatic transmission would be 3 quarts.
You may need differential fluid...check that.
if the tranny is completely empty of fluid about 12-13 quarts
i believe three qts. and it uses 80w90 or 85w140 either one is fine
The 1979 Ford F1 50 pickup truck transmission has a fluid capacity of 12 quarts. The manufacturer recommends that you never overfill the transmission.
You have to remove the rear cover on the differential housing. Once the fluid is all drained, replace cover with new gasket (or use silicone sealer) and refill through 3/8" square plug on the side of the unit.One other point to this. Replacing the fluid can be a bit tricky. By the time you get yourself, your tools, and your bottle of fluid under the truck it can be a challenge to the fluid in the differential. To ease the problem, get a small section of hose to connect to the spout of the bottle and then run the other end into the differential and squeeze. It is pretty easy and faster.
Need to know the transmission model in order to answer this.
Typically you fill to just below the fill hole, I usually use a smaller Allen wrench to check it. if it is to about the middle of the short end I just leave it. This is usually pretty close to two quarts.
Just fill it until it comes out of the fill hole. It should be around 4 liters so how many quarts that is.
4 to 4.5 lbs, depending on year and configuration (e.g., daycab or sleeper truck).
Almost 4 quarts 80w90 If posi. it requires 7 ounces of friction modifier.
The rear differential is a part of the power train, not a part of the suspension on a vehicle. It is the suspension system you need to be investigating on your vehicle. You more than likely have a broken spring.
