Hello, I'm from the Netherlands. Recently my car started to leak oil from the rear differential, or how u call it. Now its a metal slush. So I'm searching to swap it from a junkyard truck. I was wondering if I can use the one of a 4x4 ? According to my vin I have a 3.55 ratio.

 

There should be a sticker in the door, either on the door itself, but usually on the door jamb, that tells you what your rear axle is. If you can find a rear axle from the same generation truck, it should work fine. If the ratio is different, your speedometer will be off though. There should be a metal tag on one of the bolt saying what ratio it is. It may say 3.5.

Has your rear failed completely?

 

Thank for the reply ! It got stuck entirely and after it cooled down it still works but my own garage and a 2nd opinion said it was better and cheaper to replace the whole axle itself. To be more clear it started leaking oil at the pinion seal.

 

It sounds like you ran it out of oil and under load. Start looking for another axle. As a stop gap ONLY, while you look for another axle, put some large ceramic magnets on the differential cover and make sure it's got good gear oil in it. The magnets will collect the metal pieces in your axle. Those will be all through the gears, axle shaft tubes and so on. Swapping a different rear end will save you from having to clean all that out. Eventually your rear end is going to lock up completely. 2 or 4 wheel drive should fit and you just need to find one with the same gear ratio as well as rear brakes.

 

The bump stops are different between the 4x4 and 2wd I believe, but they'll work just fine.
