I'm going to change the oil in the front differential this weekend on my 1996 F250 4x4/351. I'm under the impression that I need to get a pump and suck the old oil out of the fill hole in the front.
If this is how it is done (with the axle still in the truck), waht is the best way to go about it cheaply? I have my counterpart's hand pump but he says he has a hard time pumping warm 10w40 with it. I do not want to buy a $50+ electric pump for something I will only do once every so often.
Anyone got any tricks or anything? Am I even going about this the right way in the first place? Remember, 4x4 novice here...
How do you know if you have a front LS? My rear one doesn't work at all. Is there a code for this?
Look on the VIN sticker on the driver's side door frame near the striker plate. Look at the AXLE code. If there is a three character axle code and the last character is a "2"-you have a factory front limited slip.
if you found water in your oil , i would pull the 3rd member and flush the housing to get it out. Dont get me wrong, its a suck job but so is replacing the 3rd member when it blows up when you really need it
In order to pull the 3rd member, you need to pull the driveshaft,
remove the driversside axle shaft. then unbolt the 3rd member from the driverside TTB(catch the oil). Now it gets tricky. push the passenger axle inward, remove the axle "c" clip and remove the axle. now the 3rd member is out of the truck. clean the 3rd member w brake cleaner and prep it to go back in. Install is reverse of removal. Good luck. that 3rd member is heavy!!
