mr.hicksta Posted April 23, 2012 Share Posted April 23, 2012 I'm going to be installing ARP extended studs soon while my BBK is away getting powder coated. The local speed shop told me I pretty much have to replace the rear wheel bearings to swap out the rear studs since it's 'virtually impossible' to remove the OEM ones without damaging the wheel bearing. So I wanted to float the question to the masses to get a feel for what I'm going to be faced with when I go to swap my studs out. I'm almost considering buying new wheel bearings all the way around since that seems like it'd be easier. Any thoughts, tips or recommendations would be appreciated!

devobuzz Posted April 23, 2012 Share Posted April 23, 2012 Well not a LGT but I replaced a broken wheel stud on my wife's Caravan. Pounded it out with a hammer. Wheel bearings were shot a few thousand miles later. Link to comment Share on other sites More sharing options...
DRoc7822 Posted April 24, 2012 Share Posted April 24, 2012 I really hope not... cause that would suck. That means I would've had to put soooo much money into this damn braking system that Im about to cry lol. Are you using open ended lugs or can you use closed ended lugs with the extended studs?

BAC5.2 Posted April 24, 2012 Share Posted April 24, 2012 You have to use open-ended lugs with extended studs. You CAN remove studs without ruining the wheel bearing, and using a hammer is not the proper way to do that. The PROPER way to do it, is to remove the wheel bearing and press the studs out. But at that point, it becomes a difference of parts cost since labor will be the same either way. I always told myself that if I went with extended studs I'd buy 4 new wheel bearings, install the studs myself, and then install the new bearings like that.

I'm using Drop Engineering open ended lugs once I get the ARP extended studs installed. You have to use open-ended lugs with extended studs.

From what one of the local parts guys told me, it should just be a direct swap with no need for a press on 07+ LGTs/OBXTs. Link to comment Share on other sites More sharing options...
BAC5.2 Posted April 24, 2012 Share Posted April 24, 2012 The fit for the lugs is a fairly modest interference fit. Nothing permanent, but certainly not loose enough that you could easily press them out by hand. You'll almost definitely want to use a press or a vice to get them out, and press new ones in. You should be able to use any bench vice and a deep socket to press the old ones out. You can use a lug nut to pull the new one through. I'd suggest cutting the top off of a stock lug nut (making it open ended) and using that, rather than one of your brand new ones.

mwm5094 Posted April 25, 2012 Share Posted April 25, 2012 Agreed. The hub isn't hard to get out. I would just do it for piece of mind. Link to comment Share on other sites More sharing options...
BigTDogg MA Posted April 26, 2012 Share Posted April 26, 2012 You have to use open-ended lugs with extended studs. Why? Link to comment Share on other sites More sharing options...
BAC5.2 Posted April 26, 2012 Share Posted April 26, 2012 Why? Because they are 3" long. You COULD use a very long closed-ended lug, but it'd look dumb and serve no purpose. I believe all racing bodies require, or at least strongly recommend, open ended lugs for extended studs to pass tech. It allows quick verification of the minimum number of engaging threads.

BigTDogg MA Posted April 26, 2012 Share Posted April 26, 2012 Makes sense. Some shorter extended studs could use a closed end lug nut (in general) for street use, but because these particular ones are so long, it wouldn't fit. Gotcha. Link to comment Share on other sites More sharing options...
mr.hicksta Posted April 26, 2012 Author Share Posted April 26, 2012 I checked out a wheel bearing at one of the dealerships today, and it looks like it shouldn't be too hard to swap the studs out assuming there's not a crapload of rust. I'm just relieved I don't have to spend $450 on those damn things Link to comment Share on other sites More sharing options...

carnutsx2 Posted May 10, 2012 Share Posted May 10, 2012 How about building a tool that would use a large bolt to press out the lug . Something like a offset gear puller. Link to comment Share on other sites More sharing options...
