I have more muscles then I thought I had. So now I have to replace one of
my studs on the front wheel. What do I have to do to get to it? Do I have
to pull the disc off and then seperate the disc from the hub? Then hammer
the stud out?
Thanks for more of your help

Bryan,
Rick is correct that you will need to pull the hub and bearings to fit a new
stud in. Or, if you want to put that off until its time to service the
bearings, you might do what I did when I broke one of my front wheel studs
about 10,000 miles ago. I found that a 9/16 inch fine thread grade 8 bolt
about 2 " long (be sure to measure the actual length needed), with the head
backed up with a large thick washer, would thread fully into a cone shaped lug
nut I had in my spare parts bin. This lug nut was the correct overall length
to slide in behind the hub flange from which the broken stud could be driven
out from the front. My stud broke close to the hub and you might have to have
to cut a broken one shorter if the break is closer to the end than mine was.
Anyway, because I was running the OEM 16.5 in steel wheels, a short open end
wrench could be inserted through on of the oval wheel slots to hold the lug nut
as I torqued the bolt to about 150 ft-lbs. This arrangement worked fine as
far as I could tell with neither the temporary bolt and nut and wheel coming
loose. I have now replaced the hubs with new ones from Cinnabar and they came
with the longer studs for Alcoa. So as Arch would say, that's what I did---you
may or may not have the same results But good luck anyway.

Bryan,

I don't recommend using a hammer, but a small hydraulic press will do the
job easily. Any local garage or machine shop should have one. I used this
job as an excuse to buy one from Northern Hydraulics. About $80 IIRC.

Be careful if you do this yourself as the old studs require quite a bit of
pressure to break free. Be sure the hub is properly supported.

Patrick,
I've been looking for an excuse for about 20 years now to buy a press. This
might be the time to get one. How much space does the press you bought take
up in your garage?

I have limited space in my garage because of all the other junk I have.

Also, how tough was it to R&R the studs?

Just guessing, but the footprint is about 16" X 24". I can measure it
tonight if you want a precise measurement.

Not hard at all. The worst part was supporting the hub when pressing the
studs out due to the odd shape of the hub. Need to be sure that the ram is
pressing straight down on the stud too. It takes a lot of pressure to break
the old studs free and makes a pretty good racket when one comes loose.

Pressing the new stud in is a piece of cake. I used an impact socket to
support the hub flange and the press pushed the new one right in.

Just guessing 'cause I didn't time myself, but to R&R eight studs would take
me about an hour(not counting hub disassembly) and I work pretty slow.

No that not's necessary. Your guess is good enough

Patrick,
Well since Cinnabar quotes $157.50 for the labor to R&R the studs at the time
you
have them install Alcoas. I figure if I do it, that will more then pay for the
press. Of
course I may never install new studs, but at least I can tell my wife that I
will be all
set to save $157.50 should replacedment ever become necessary. That's how I
justified
buying the Warner Bearing Puller that I've never used. I figure you have to be
prepared.

Where did you buy the studs? Cinnabar sells the set for $132.

I bought them from Cinnabar. That was probably 1 1/2 years ago and I didn't
know that an equivalent was available elsewhere. Still, $2.75 a piece ain't
bad and it saved me from driving all over town trying to find the
equivalent.

That's what I did,
Patrick
