driveshaft bolts

davins130 · Apr 15, 2005

what kind of socket do i need to get the driveshaft to differential bolts out? it looks like some kind of inverted torx or something.

AznStanger3v · Apr 15, 2005

its a 12 point. well, ive been doing driveshafts on the modular cars lately so thats what they are on there. it kinda sounds like a sharp 6 point. i cant remember, its been long.

davins130 · Apr 15, 2005

what?

AznStanger3v · Apr 15, 2005

-could be a 12 point like the modular cars. Try using a 12 point socket on it.

To remove the driveshaft which is held in by 4 bolts in where you will need a 12 point 12 mm socket or wrench to fit over the bolts perfectly. The driveshaft bolts are commonly very stubborn to get off. If you can get a break-over bar on the bolts then you should be able to break them loose. I use the appropriate wrench and put a hollow bar over it and break them loose that way. It helps on the leverage. When you go to remove the bolts you will need to rotate the driveshaft to get an angle on the bolts. When you find the right angle put the car in gear (take your shifter and temporarily pop on the tranny and stick it in gear) and put on the e-brake to prevent the back tires from turning so you can break the bolts loose. Once you have removed all 4 bolts you are now ready to remove the driveshaft. When you pull the driveshaft out from it’s trans housing do not be surprised if transmission fluid comes out (normal). You can buy the driveshaft “plugs” that will be placed where the driveshaft was inputted or you can use a rubber band and ziploc baggy and rig it up to catch any of the fluid so you don’t lose to much...

Good Luck

12 point 12mm wrench/socket will be needed...

I high recommend using an impact wrench on those. I had to buy a 12-point 12MM socket from Sear's. Trying to get them off by hand was nearly impossible, they have red loctite on them too. Then my friend brought an impact wrench and compressor and they were all off in 2 minutes.

how similar in difficulty would you say they are to get off, when compared to stock header bolts?

5spd GT · Apr 15, 2005

I'm not sure how you would get an impact gun on them without the use of a swivel.

They are harder to get off (torque wise) than header bolts...I believe the driveshaft bolts are torqued to 90-100ft. lbs...or so...with loctite on them as well...

Just use a cheater bar and you shouldn't have to much trouble...

I remember we just used an extension, I think it was 3 inches, on the impact wrench.

HISSIN50 · Apr 15, 2005

if not mentioned, a little heat takes care of the threadlocker pretty well.

do reapply threadlock once done or they might back out on you. i do it like David does - no issues. i dont have the guts to use a gun on 12 point bolt heads.

davins130 · Apr 15, 2005

yea 12 point, easy to take off, just used a small extension and a ratchet, once they broke loose they were finger tight.... thanks that bolt just looked weird and confused me

Agreed.

I've never been able to get anything more than a box wrench on there and then used a bigger wrench as a cheater bar. With a little heat from a small propane torch they come off. You will occasionally hear stories about peopel snapping them off because they use nothing but a breaker bar or something else -- you don't want that happening!

5spd GT · Apr 15, 2005

I remember the first attempts (now I do recall using an impact - friend was anyways while I was messing with the exhaust removal for clutch swap) that we twisted a socket in half on the driveshaft bolts...lol. So we had to get the torch out

I know the aluminum driveshaft I have now won't let me get a socket in there anymore where the stock one did so it is a bit more of a headache

KingDiamond · Apr 15, 2005

Oh yeah and if the head of the bolt is a little twisted when you take them out then it's a good idea to get some new ones. I got 4 new ones for $8 at my local dealer.

davins130 · Apr 16, 2005

thats weird it was so hard for you guys to get them out, they were no problem at all for me, just used a ratchet and turned the driveshaft to get the bolts to the bottom for each one.

fivepointNO · Apr 16, 2005

Some bolts are more stubborn than others is all. I've always started with a 12 pt 12mm shortwell 3/8 drive socket and rachet. If that doesn't work, I'll go to a wrench unless I'm feeling lazy. If so, I use a 3/8 drive impact, impact socket and swivel. Makes quick work of any d/s bolt that way. Of course, if I'm doing a tranny swap or ring & pinion removal, the impact was already out.

davins130 · Apr 16, 2005

i wish i had an impact handy in my garage

My Craftman impact gun has 660 ft-lbs of torque in reverse at 90 psi.

HISSIN50 · Apr 17, 2005

hook a honda motor to the bolt and break it loose. oh wait, they dont make enough torque.
