Slide the inner cv boot back remove the circlip and slide the shaft out. This is for the isuzu diff

90 with a v6 in USA. That would be the 3.1 chevy engine and trans. The petrol isuzus here had the 4 cylinder 2.6 engine. Do you know if you have isuzu or dana diffs.
If it is the isuzu front diff first jack up car and support power A arm. remove the cap on the free wheel hub after marking its position remove circlip on half shaft remove tie rod end and top ball joint. unbolt brake caliper and move out of the way. This should allow the axle assembly to roll forwards off the stub axle. undo clip on inner cv boot reach inside and find a wire spring clip in the thick black impossible to clean off grease and remove. This splits the inner cv so the outer part of the cv stays on the diff but the inner part and axle pulls out. There are 5 or 6 large ball bearings in here that may fall out. Dont lose them and remove the ones that dont fall out. On this end of the axle is a circlip. Remove this and the bearing housing comes off the axle followed by the cv boots.
Dont try and take the outer cv off the axle It can be done but is very hard and if your new cv has the axle attached you dont need to. Swap the boots and inner cv to new outer cv/axle assembly New boots is a good idea. clean and grease as required with cv grease. (molybdenum) put the balls back in the housing push into the outer part of the inner cv replace wire spring clip put the boots in corerect place and do up the boot retaining clips. grease the axle shaft lift the hub assembly back onto the axle reinstall ball joints brakes etc. finished
If done by the book a cv replacement is 4 hours. The above method takes an hour and a half including beer. I have seen it done in 15 minutes on a mu/amigo but it was done by an x mechanic now prison guard.

taking the part in the diff out is the way its meant to be done but it adds so much time and effort that its rarely done. By leaving it in place it cuts the job in half

should the auto locking assy. be greased or dry ? the pick in my book looks like there clean mine are full of grease. it does say the cam & the locking plate should be clean.

I would of said lightly greased If it looks like it was never greased though dont grease that part. We try to avoid auto hubs if we can.

i am wondering if i have a problem with my cv joints i have manual locking hubs and when i lock them in with the wheels off the ground the left hand side turns freely but the right hand one has a hard spot in it when turned by hand the cv shafts were both replaced i pulled the diff housing out and did the lot this only seems to happen when the suspension is fully extended as if i put the jack under the rhs and jack it up off the floor it turns ok

i may be wrong but a normal limited slip diff. "stock" only turns one side at a time , ie lift left & it turns & vise versa.....does it perform well off road you may be over thinking it as i often do..

does sound like a cv issue
Have you done a suspension lift? If so did you flip the top ball joint and or trim the bump stop. If so you might be operating the cv at its limit which is not good. Are they genuine or aftermarket cvs

15mm isnt a lift. Only other test is to remove the cv and move it throught its full range by hand.
How much of a tight spot is it? It might be nothing worth worrying about

G'day guys! First post here.. anyways I've just purchased a 96 Jackaroo (Manual Hubs) and it was missing the front left cv shaft. I've purchased a new one but I am unsure of what holds it into the hub assembly? I can see there is a small cut out for what would appear to be a cir clip? but is there anything else that goes on the shaft before the cir clip ie. splined washer or the like? any help would be greatly appreciated!

Cheers Skottie

the spline is part of the locking hub There should be some shims to adjust the preload on the hub seal
