    Diff Replacement

    Here's one for all you mechanics out there.
    Is it possible to change a Diff using axle stands and a trolley jack once you have removed the drive shafts/prop etc.

    I had a look at mine, I think it would require dropping the exhaust assembly, I don't think the actual body of the diff will come through the gap between the pipes, and the prop shaft bolts look to be enclosed by the heat shield too. There should be enough movement in the drive shaft CV joints though. Looks a heavy lump?

    So yes it can be done with axle stands and a jack. But it's not a quick evolution if it's a one man job.

    You can see what I mean on this video from about 5.35 minutes and seconds onwards.

    I believe it is possible..

    But like any old final drive unit it is a lump and a half.

    Thanks all for your replies. Yes it is a heavy lump ( I've got one on the bench that I have put new drive shaft oil seals in ) Looking at it from underneath I don't think the exhaust has to be removed as there is enough space for the diff to drop down once everything has been disconnected. My main worry is getting the replacement one back in on a trolly jack as most of you will know as the jack is lifting up it goes in an ark and this could cause problems locating the said lump! I have a Pitt in my garage but I would need something like a transmission jack to do it that way. I will sort this problem out eventually but it's nice to get your feedback.

    Keep it coming.

    If you could mount a piece of 3/4 ply to the cradle on your jack, big enough to support the diff, and use a few blocks of wood, 6 inch nails, something similar to keep it central and also stable the jack lifting in an limited arc won't be such an issue, because it's also moveable as you line the diff up with the hole?

    Rather than trying to balance the diff on the cup whilst you jack it up.

    Thank's for that Lost it. I don't have any problem steadying the diff on the jack, as I have put it on the jack and wheeled it down the garage floor and it is very stable. It's just the arc bit that I am concerned about. However the garage floor is smooth so I probably could move the jack slightly back and forth to get it located. But thank's once again for your input.
