Shouldn't be a big deal. You just beat them out with a hammer.

I don't think this would be a big deal. I believe they have a serrated surface where they are attached to the disk. As the previous poster said, I would think you merely need to give them a good "whack" and the old one should come out and the put the new one in and tap on the back and it should go into place. They aren't going anywhere as the backside has a lip to keep from coming out the front side. Easy does it and you should be fine.

I take it back. It could be a little more harder than I had imagined. This should help.

Getting too happy with a hammer can easily result in some very expensive damage to wheel bearings, races, and CV joints!

The new lug bolts can be pulled through the hub by using the wheel nuts and a cross wrench. Also, when you tap the old ones out, be careful not to mushroom the ends of the bolts. You already have enough problems.

Good advice. Probably best to use a soft edged hammer such as brass.

It's worse than that! To replace a stud you need to take the whole hub off. They are not tapered roller bearings and are a press fit and will not pull off even with a drift hammer type puller.
I gave up before destoying my wheel bearings. I was told that this is the usual result on dissassembly.

I was going to put a set of longer studs in so that I could fit my 8mm thick wheel spacers to make it easier to put my snow chains on, (i am running 245/70-16 AT tyres).

All Hyundai needed to do was give us a half round cutout on that plate so that we could rotate the hub and knock the studs out one at a time but no such luck. A simpe job turns into a major project.

If you find out any different let us know.

Cheers Bruce

When you take the big centre nut off, the drive shaft slides back on its spline so you can't use a normal puller, hence why I fabricated a drift hammer puller. When I decided I had banged it hard enough with no result I made a call to a guy that worked at the Hyundai dealer and he explained to me about the modern parallel type wheel bearings.
I put it all back together and next time I was talking to my front end specialists I asked them and they confirmed that the bearings usually get damaged when dissassembled.

I believe that to get the hub off you need to take the hub carrrier off the car by unbolting the tie rods and all the other mounting bolts, ABS cables etc and put the whole lot in a press to get the hub off the carrier. Then replace the studs (the easy bit), fit new wheel bearings (the expensive bit) and put it all back together.

I haven't done this, so as I said, if anyone know any different let us all know.

I decided to defer putting my longer studs in untill I needed new wheel bearings, apparently that could be a long wait as they are designed to last a long time.

Cheers from Tasmania.

Good info EW7-. What you describe is a pretty typical setup on a FWD, floating rotor type vehicle. Usually it's not just a matter of popping the lug studs out. The bearing hub assembly needs to be replaced. If it's a higher mileage, 4+ yr/old vehicle, I'd just replace the hub assy.
