differential took a poop
Just replace it with a stock one from your local FLAPS (Napa, whatever). I
always just get a whole axle, that way I'm not playing in the used grease
as much, though some places sell them without the grease in them, so you'll
be putting new grease in. Ask when you buy it if it needs grease. Anyway,
Daun and I have all kind of happy (?) memories about doing these in the
field. You will need a bigass socket for the hubnut, a 30mm I think?
Someone confirm that. And you'll also need another oddball tool, a triple
square (spline drive) bit for the bolts on the tranny end. They should pop
off easily, they don't get torqued in too tight. So with the car on the
ground, free up that hub nut, it'll be on there good. I always need to get
an old fencepost on my biggest breaker bar, and really reef on it to get it
to crack. Just make sure the socket's on that nut good and square. Slack
off the lug bolts, then jack up the car, support it on jackstands, with
wheel chocks and ebrakes on, and remove the wheel. Then remove the innner
bolts one at a time. Clean out the heads with a pick and tap the bit into
place to make sure you don't strip them out, which would suck. This will
involve rotating them into a place where you can access them as you move
around that flange. I've been trained to use a series of wobbly extensions
and a big long extension so I can actually do it without getting under the
car. With luck, you can position the wheel to allow the hub end to pull
out, and you're good. On my 16V I've detached the ball joint and some of
the underpinnings to do the DS one, not sure if it's an absolute necessity
or not. Hub nut torque is listed as 173 ftlbs, which is to the RFT spec
(Really Fucking Tight) You don't want that bad boy wandering off on you. 33
ftlbs for the little axle bolts, which is NOT RFT, more like NTTAA (not
that tight at all). Something like that anyway.
Ah, the memories. Daun and I did two of these in the Buffalo Airport
parking lot. We sure know how to have fun. GL eh?
