rear half-shafts question

Hello Board-

From my investigations, it appears that at least one of the half shafts has given up the ghost in the rear of the 90. I searched and found a few articles on DYI but I'm curious as to which ones are the best out there or is it simpler to just take to dealer. Does not look like a huge job, but.....

Thanks much!!

KCD

My hunch would be it is the diff as that usually goes first. In any event, they are real easy to pull out. Take the wheels off, undo five bolts and pull them out.

Undo the 5 bolts on the drive flange and pull out shaft. Depending on where it broke will determine if getting the other half out or not. Can't hurt to have a look and try. It is a five minute job. Come back for more advice after you have got the flange(s) off.

There is no reason to remove the wheels.

Have a magnate on extendable arm handy to pull the second piece that you can't reach.

Unless you have alloy wheels, that is.

If you pull both shafts and remove the broken pieces, you want to put the drive flanges back on to keep dirt out of the bearings and then you can drive with the center diff locked.

I'm not sure why you would go to the dealer at that point, though, as you just need a new shaft and stick it in.

Also...did you break it off road? If so, perhaps you should purchase stronger shafts.

After you pull the shafts I'd recommend draining and inspecting the diff oil. If its clean its probably safe to drive. If there's chunks and whatnot I'd drop the rear driveshaft and lock the CDL before driving anywhere, juts to be safe. Of course, once you have the half shafts and driveshaft yanked, its only a few more bolts to pull the whole diff out and inspect.
Shop!?? You don't need no stinkin' shop!! :D

Hah!

It can't possibly be that easy, if someone could point me to a step-by-step I might be willing to try. Also, I looked for stronger ones and all the ones I could find were out of the UK...although I have never been off road and don't plan on going anytime soon..any suggestions welcome...

Sure, it is that easy. It is designed to be easy, to be repaired in the bush.... Just stop fighting it. You own a Defender and it will hate you until you learn how to work on it.

USA source, although you should never be scared of buying from the UK....

They are the same in NAS defenders as disco 1 and mid 93 and up range rover classics so used spares are cheap enough and plentiful. No need for HD ones absent heavy offroad or substantially larger tires. Like I said, by bet is on the diff.

I once took some advice from Bill at GBR years ago. Stick with 33inch tires and stock shafts. They're cheap to replace and easier to carry/replace than a diff. You don't want your shafts stronger than the diff, right? Makes sense. I've wheeled some tough stuff. Tougher than I probably should. Tougher that I probably will in the future as over landing has more of an appeal to me than trying to rock buggy a daily driver.

to me and I think I will follow that advice....as long as I have this 90 and perhaps as long as one of my daughters has it, the roughest thing we will go through is a muddy road!

good advice...

I got on RN and see a half shaft coupled to a cv joint? I can and have done work on this thing but I may be a bit over my head here...

Wuh?

Rears have no CV. It is just a shaft. Seriously, five bolts per side. Only trick is to refit them with the correct torque as they tend to back out.

He is right. Don't over think this till you need to. This is very easy. I don't do most of my wrenching....but this is a job I have done a couple times.

Super easy, no joke. Wish I was closer, we could do it on the side of the road before you could finish a cold beer. My only advice is get some Right Stuff and resell the flange when you put it back in.
