Any tricks removing an inner CV joint from diff ?

[mu4meandyou]

While attempting to remove my RHS inner CV I've struck a snag. It was my impression that with a bit of leverage the inner CV cup that attaches to the diff would slide out. Well no matter how much leverage / persuassion used it seems quite happy to stay where it is. I have the outer and shafts out no worries but this last part has proven frustrating. Used tyre levers, pinch bar, cold chisel as wedge and all no luck. Are there any other tricks ? I wasn't expecting any issues here

Finally found the right spot in a trooper manual and apparantly it's called a DOJ case assembly. Looking at the manual it appears you have to support the diff and remove the bracket on that side. I thought it only supported the diff housing but appears it holds this case assembly and seals/bearings in as well. The replacement new CV was too long anyway so had to put it all back together with a clean and new boot.

Now off to sort out why the replacement CV was close to 50mm too long on the shaft between the joints. My front lower control arm bushing was also to big. Asked for jackaroo/rodeo bits and checked they were the same as each other before ordering. Talk about a frustrating weekend....

All the good books say do it that way but unless there is a good reason to remove the outer part of the inner cv noone does it that way. It adds about 2 hours to the job.
Undo the large strap on the inner cv boot and pull back Put a finger in the hole and feel around for a wire spring clip and pull it out The inside part of the cv now pulls out of the outer part leaving the outer in place. This outer part is almost indestructable so why mess with it. The only bad part about doing it this way is that it can be fiddly to putt the band bach round the cv boot in place but once youve done it 3 or 4 times you wont notice.
The Mu suspension is the same as the 89 - 91 Jackeroo not the 92 onwards. It sounds like you got the later parts. Ask for UBS55 or UBS 17 chassis numbers
I have seen a cv changed in 30 minutes in a field from the time my hilift was borrowed to the time it was given back. I do them in just over an hour but im always cleaning and replacing the boots at the same time

Thanks Geeves.
I figured the CV was the later model ubs69 given the size difference, and the same goes for the bushing. I confirmed with him ubs55 when ordering however that may have been overlooked... I rang a couple of CV specialists and they said it simply pull out - now I know better. Since I bought a complete CV I was preferably going to use all of it.

Looking through various workshop manuals, and the www.myisuzuparts.com site, my lower control arm looks different to 89-91 Jackaroos as they seem to have only a single lower bush. Mine has two lower bushes (front and rear) and look like the same year model Rodeo, and similar only smaller to 92 onwards jackaroo. I'm going to call the supplier tomorrow for a measurement check as I need bushes for 32mm arm where as the ones provided where closer to 36mm.
