Please let me know what is the best way to fix this?
one of 6 bolt on my rear wheel broke.

1) Find whole drum brake cover with complete bolt?
2) can I just replace bolt itself?

I don't know exactly what happenned, but my wife was helping me to change tires and i break loose she was loosing bolt - get tighter even turning counter clockwise - broke bolt, piece of the bolt is in OEM lug nut.

see pic below

 

If I understand you're writing correctly, you have broken off the nut with some of the stud still within the nut and the stud is still stuck on the rim? You are wondering how to get the stud off of the rim? And the remaining stud out of the bolt?

If that is the case, then you will need to possibly heat up the stud left in the rim, and bang the stud out of the rim (careful not to damage the rim, especially if it's aluminum) though your rim does not look like it's aluminum...

Unless your lug nuts are extra special, I wouldn't worry about it - just get a new one.

Next you'll have to get a new stud and bang in into place of where the old one was.

That should be it. Hopefully this helps, I'm not sure if I've read your question correctly, the English appears a little open for interpretation.

 

Remove the tire, remove drum, smash remaining stud off with 5lb sledge and punch.

Thread in new stud, take lugnut and tighten the hell out of it and its in there..

 

just leave it i been running 5 lugs on one of my wheels for months

 

Change all six while you are at it. I would get it fixed, you never know. Shouldn't be too difficult.

 

Once studs are significantly overtightened, they become weak and will tend to break. If you have one break, chances are the rest will break.

Replace all the studs on that axle while you're there. I'd suggest genuine parts, as they're the best fit. Aftermarket studs can be a loose fit = trouble. Unless you go ARP or something.

To change them, remove the drum and just pound them out with a hammer and pull them in with a lugnut. Use grease and a BIG washer. The steelie type lugnuts work best if you put the flat face up against the hub.

To prevent this from happening again, use a torque wrench and tighten your lugnuts to 75-85# and no more. Spec is 76ft.lbs. Never use an impact wrench, or allow anyone to impact wrench your lugnuts on. Unless they use what's called a torque-stick which limits the torque.

 

I agree with using a torque wrench to tighten. Most lug nuts are way too tight. Also, use some anti seize on the threads, this will prevent most stud breakage.

 

i was pretty sure that the '93 axles are still like mine ('88), and they use press in studs. if that is the case, you'll have to pull the tire, drum, and slide out the axle shaft and press in a new one. and like jason said, i'd replace all of them while you're in there.

if they are the thread in type, thats news to me and i just wasted my time

 

In my 94, The stud could be removed without taking out the axle. I drove the broken stud out with a punch, and installed the press in replacement by tightening the nut against a block, which seated the stud. Why replace a stud that is not broken?

 

You can use a lugnut to 'pull' them in instead of using a press. Just be sure to use grease an a few large washers under the nut.

Why replace non-failed lugnuts? It's called insurance. Easier to do 6 at once, than one at a time...

 

Thanks guys.

I used to use the shop torue wrench when I was in California.
But never used on lug nuts.
Since I moved to Ohio, I don't have it and it is kind of expensive for me.

I will change all the bolts.

How about front?
Is it basically same as rear?

Once again thanks for your information.

 

I know this thread is old now... but i thought I'd address the question of "how did this happen?" I have the exact same rims and the first time I went to rotate them after they were originally mounted I broke 4 of the 6 lugs off when trying to remove the lug nuts. The rims require conical style nuts, and if the nuts are not seated properly (into the recessed hole in the rim) they will improperly torque against the outer edge of the hole... then you have no other option to get them off... they just break after they've been overtorqued.
