How Do I Replace Wheel Studs?

[krush]

hello,

ive looked around, found tutorials on how to remove the brake pads, then the calipers, but then.. whats next?

also checked in the r32 gtr service manual, couldnt find anything about the studs, only the brake pads.

my car is r32 gts4 turbo,

one i get the caliper off, is there much more to it? im guessing id have to take out the centre pin, unscrew something and perhaps the middle hub would fall off, gaining my access to the studs?

any help would be greatly appreciated

thanks thanks,

shaun.

If GTS4's are like GTR's (and I think they are) there's no need to remove the front hubs to get the studs out and new one's in. Disc and caliper have to come off, of course, but if you look at the backing plate near the hub with the caliper off you will see a small semi-circular cut-out. At first it would appear there's not enough room to get the studs out, but nissan put the cut-out in place to give sufficient room to (just) allow enough room for th studs to slip out at a bit of an angle.

To get the stud out, turn the hub until the one in question is lined up with the cut-out. Then using a reasonably hefty hammer, drive the stud out toward the backing plate. Sometimes that can take quite a bit of force, but be careful not to 'mushroom' the end of stud your striking otherwise you'll make more trouble for yourself. Personally I use a piece of aluminium or brass as a drift which distorts rather than the steel of the stud. Once the stud comes free, angle it out through the cut-out decribed above.

Slip the new stud into place. Since it's difficult to 'drive' the new stud into place because you can't get to the back of it with a hammer, I 'draw' the stud into place using an old wheel nut with the end cone machined off and a spacer. Tightening the nut up with the spacer gradually pulls the stud into place. Another way is to put the wheel on and use that as the 'spacer' and gradually tighten the wheel nut until the stud is seated. If you have a steel wheel for a spare, use that as the steel wheels are a bit thinner at the stud points which gives a bit more thread to use. Whichever way you you choose, go carefully and if you feel any resistance stop and check things. I also use a bit of grease on the threads and contact faces when putting the new stud in which 'helps' things on a bit as well as a bit of insurance against thread galling.

Hope that helps.

Thats basically all I did with my R30 when a stud was broken..

Not too hard

To stop the stud mushrooming, put a wheel nut back on the stud about 2/3 of the way onto the nut. Hit the nut instead.

But you need to be careful with the bashing, yuo can damage the wheel bearings if you hit it too hard.

Rears are the same there is a small cut out to let the stud through the hub.

To put the new one in, you put the stud in until it is tight, then put a wheel nut on. As you tighten the net the stud will pull itself into the hub, keep turning until the nut is tight (110nm) and then the stud is in.

BTW this is in the GTR manual I have seen it before.
