E 350 with dead differential

I thought I would take advantage of the numerous learned readers of this forum to see what I should do with my E 350 van.

It's a 97, with 3.73's and posi-traction. My mechanic, whom I have used for years and years with great results, says he can move the drive shaft up and down with his hands at the differential. He says the differential is shot. He didn't even want me to drive it home. He wants about $1600 to rebuild it.

The van is not worth much more than that (235,000 miles, 17 years old), but I hate throwing stuff out.

How hard is it to swap out a differential myself? Junkyard swap?

Any suggests would be appreciated.

  • Junkyard swap is not hard but those axles are heavy...assuming you can get one disconnected at the rear u-joint so that the pinion shaft is still in place and adjusted correctly. Also need to make sure you get the right ratio...you may be able to pick one up for a few hundred, plus new fluid for it, you may get the job done for half of that $1600 and get a few more years out of the old girl.
