Default DANA 44 side yokes needed

Hi all,

I need some replacement side yokes and the LSD center shaft for a DANA 44. Can't seem to find anywhere to buy them.

I have a huge amount of end play in them, and the rear camber adjustment is maxed out yet still has negative camber. (this is due to the side yokes being too far in on the diff)

Replacing the snap rings with thicker ones will NOT correct this issue, either the ends of the side yokes have significant wear or the center shaft of the LSD is heavily worn.

If anyone has some good spares or knows where i can buy them please let me know.

Thanks!!

I have a couple NOS 'short- axles' (side yokes) a NOS differential complete but I don't have the shaft. If the shaft lock is secure and there's no play in the shaft in the differential what about the pinion washers? When inside we always replaced the pinion washers (2 of them) when doing clutches etc. It would seem more likely that you need a differential 'case' vs the shaft.

I understand what you're saying, but that doesn't explain the excessive rear camber issue that can't be adjusted out, what that says to me is the side yokes are too far into the case, not simply able to move too far out.

Since the half shafts are the upper suspension arm and the side yokes should be quite snug against the center shaft of the LSD, the only way i can see the side yokes being too far in and having so much end play is the ends are worn down like seems to happen on later C3s, or the center shaft of the LSD is worn allowing the side yokes to go in futher than they should.

The pinion washers would allow the side yokes to move out further than they should for sure, but not inwards, and in that case i'd still have no problem with rear camber while the car is on the ground.

Unless there is an adjustment of some sort i have never found before to stop the side yokes moving so far inward to create excess camber?

See video of it here, left side is a bit worse, both sides move like that independently without any effect on the opposite side.

Without the D44 being on the bench it's very difficult to diagnose. It could be assumed you have enough of an issue that you remove it and do further diagnostics. What all it needs can't be assumed from that video.

I know that yes, but what else can it be if the side yokes are too far in and have so much end play, and the only thing that stops them moving inwards is the center shaft of the LSD?

I know i need to remove the diff from the car, but unless it is not going to be one or all three of those parts i don't know what else it could be.

Everything in the suspension is new, the issue was worse prior to replacing the bushes, the poly bushes installed are all in as they should be, everything else is tight, the left camber adjustment is maxed out to remove as much negative camber as possible and it is still almost 1 degree. if i raise the car off the ground the camber goes positive as the side yokes move outward, as expected.

The last person that asked me for 'short-axles' after he removed the D44 he needed way more than what he asked for. He thought he needed a single 'short-axle' and needed much more - much more!

Yes, but what could cause the issues i've just described? Especially the excess neg camber?
