Has anyone snapped an axle stud launching on street tires? I was just messing around today...nothing major..a couple of launches from two stop signs by my house. I didn't hear anything until I started back to my house and hear this KA-CHING near the gas tank area. I immediate stop and pull over. I didn't find any rock, but I did notice that one of my lucknuts were missing! WTF? I first thought that maybe someone was trying to steal my wheels and just didn't finish the job, but then I see this shiny lucknut about 20 yards from where my car was driving. I picked it up and half of an axle stud was buried in the nut. I checked all my wheels and it turns out the rear passenger was missing one or at least half of the stud was missing.

Damn..is all I can say...now..how easy/hard is it to replace the studs? I want to replace them with all arp ones so that this doesn't happen again...

Not that hard, it does happen! They pop out the back of the axle, good luck getting them out, usually takes a 5 lb. sledge or a lot of elbow grease!

They are gonna be so hard to take out man it is rediculous. But yeah, you have to pound the shit out of the stud AFTER you have taken the axle out. You need to get the axle outta there because you don't wanna accidentally hit your brakes and fuck those up too. Once the axle is out, start hitting directly on the broken part of the stud and she will pop out. Use A LOT of penetrating oil too. They all come out like that and installation is the reverse of the teardown process. Good luck and I hope you got some muscle

I removed my studs on both sides of the car without removing the axles.

Two options: If rear drums, remove the wheel cylinder in the drum brake-- then you will have adequate clearance to pass the stud through.

If rear discs, find a convenient place on the splash shield mount (cast iron) to grind away and create enough space to pass it through.

Worked for me, with a 4" stud (much bigger than stock)

Oh man..this sucks. I really didn't want to have to take the axles out...jeez, I might as well put a driveshaft/ujoints while everything is apart...the fluid in the differential is probably (imho) one of the nastiest smelliest fluid known to car-mankind and the thought of having to drain it..ugghh..

Jeez..it is not my day (or night). My father borrowed all my tools last weekend and I just found out that some fool just stole them out of his garage on Sunday morning...CRAP.CRAP.CRAP!

in most cases you DO NOT have to remove the axel to install set of axel studs.......Here is a quick and easy way yo do so....

#1 pound out the old ones..........Dont worry you arent using them again so you can pound the FUKK out of them.Once they are all out refer to #2

#2 go buy your desired studs which should be 1/2 20's.Also buy some 1/2" 20 cheapie OPEN(throw away) lugnuts.grab the new stud and grease it thouroughly.grab one of your "throw away" lug nuts and tighten it as much as you can by hand then tighten it with a deep impact socket(13/16) and a air impact gun(easier) or a socket wrench.it should pull it in to the axle.

From there you should be done............

Hope this helps

Okay. I asked around and it looks like it is possible to change a stud(s) if some grinding is done, but that might not be a good thing as that probably weakens the integrity of the components just to make things fit. Anyway, it looks like it might be an r/r axle thing just to change the studs. Anyone in the Fremont area that has done this and is willing to do it for pizza/beer? I will help of course...just don't have any tools (they were STOLEN) and of course, I could pay a little instead..not a lot as I just bought a big freaking diamond ring from my now fiance...

the only 'integrity' that you are damaging is for the cast iron mount to the splash shield for the brakes! it's held on with three 1/8" style screws yet the cast iron is like 0.5" thick! lol.

I'm pretty sure my splash shields aren't going anywhere after grinding on it a little!

That true..just didn't want to hack things up too much and the splash shields are no big deal to me...willing to let me borrow you die grinder or you could grind some holes for me???? Where are you in Fremont...pm me.
