dana 44 rebuild?
I'm begining to suspect the passenger side yoke is moving in and out slightly (I'm still getting some movement on the tire front to back after a wheel bearing change, not alot but still its got to affect handling).
my question is:
will a bearing and seal kit be enough to cure this?
or will the yolk also need replacing (anyone know from experiance?).
the vette has 108K miles on it, rear end doesn't leak or make noise. but since I do some DE track days/autoX I'm wondering if it wouldn't be better just to replace the whole rear end (pricey).
tell me your opinions

The wheel bolts to the wheel bearing, and the wheel bearing bolts to the knuckle. Is the knuckle moving? How are the camber rod and tie rod ends? A bearing kit is not likely to have the select fit snap rings for setting the yoke shaft end play. Check with your parts supplier to see what it takes to get the snap ring package. You won't know about the yoke shaft until it is out and you inspect it.

CFI-EFI,
everything else is pretty new, wheel bearings (new), poly bushings (2yrs old), tie rods(new), U-joints(<1yr).
it seems the rear end is the only thing left.
I've looked at the service manual and don't really see how the yolk handles inward stress's, it has a tapered bearing on the inside but the outer bearing looks to be straight roller bearings? strange, I would think another tapered bearing would be what they should have used.

The tapered bearing is for the diff case to carrier. Those bearings are actually pre-loaded. The straight needle bearing is the ONLY bearing for the yoke shaft. The inward movement of the yoke shaft is controlled by the outer shoulder of the shaft against the bearing. The outward movement is controlled by a select fit snap ring in the groove in the inner end of the yoke shaft against the inside of the side gear.
Again, I would confirm that the knuckle moves with the wheel assembly, before I'd tear the diff out of the car.

I agree,
I'll set up a dial indicator on that yoke and see what the movement is before doing anything.
hopefully the service manual has acceptable tolerances.
thanks for the input CFI-EFI
update:
well I just checked things out with the dial indicator, good news is that the rear end yoke is fine (.002-.003" movement max if any).
bad news, its the brand new wheel bearing.
with the indicator at the rear of the rim and applying force front to rear I get .050" movement.
I can tell its the bearing because I can see the wheel bearing yoke move inside the spindle housing. dang it I should have went with the GM units!

At least you caught it BEFORE you pulled the diff.
