Front diff issues

So I already posted that I'm looking for a new front diff, but I wanted to post 2 videos of how its currently working.





It looks like the carrier (Trac-lock) is stuck locked and the passenger side axle splines mostly stripped on the diff side.

Danny, pull it and you will know exactly what's wrong. You have to pull it anyway!

Have you pulled it apart to actually see? What makes you think the splines are stripped?

Before you go buying a diff, take everything apart and see what is actually broken.

Could be broken at the CV. You need to pull the right side and see what you find. You sure it is not just the drive flange splines? It is very doubtful you would have stripped it at the diff or damaged the diff.

Danny,
Have you pulled the rubber dust boot and removed the snap ring to look @ the drive flange ? Takes 2 mins.
As I was saying @ the Cove I have stripped several of them out. They are soft cast iron and as it was explained to me they are the "fuse" in the drive train, ie designed to strip out easily. Many say too easily.

They are cheap too.

Yep, pop the rubber cap off, I bet the drive flange splines are stripped

Thanks for the help everybody, I pulled it apart down to the hub nut (then realized i didn't have the hub nut tool). I'd tap it off with a hammer and screwdriver but then i'd be hesitant to re-use it. Ordering that this week, going to have to try again next weekend. Video below shows the drive flange...

Its 2-1/16" but 55mm (Toyota size) will work as well, and is usually available at the local Vato-zone.

Call Will Tillery as soon as you verify that it is in fact a broken CV.
Last time I was at his shop he was tripping over all the CVs and axles aging around...

Oh and btw Danny,
If you need to go cheap, get yourself a RoversNorth Hub socket.
http://landroverparts.roversnorth.co...D-STEEL&key=it

You can use a long screwdriver or bar or mod it.
I welded an old 3/8 socket on a piece of scrap metal to make mine ratchet driveable.
The stamped socket is very strong; I've been using this one since 2002.

Pulled the wheel->hub->stub axle->CV and voila, there's a broken tab and one of the ball bearings was floating around in there. I cleaned out the swivel but can't seem to find the piece of metal that broke off however... I'm hoping its either pulverized from driving around in there, still stuck in the CV itself or inthe mess of grease goop that poured out.

see pics below.

One thing to note, the splines at all ends of the axle look fine.

Danny. Nice chatting with you. The part that is cracked is the "star". Very common failure. Keep whacking the cv until it comes off the shaft then check the splines as we discussed. Call me again if you need more help.

And I am sure you know Randy Williams is close to you as well. I'm glad you took the time to investigate before getting a diff.
