Best way to break loose drive shaft nut?

DTriumph · Dec 12th, 2004, 03:01 PM

Ready to remove my 240sx's engine to replace with SR20det...and I can't get the last bolt of the drive shaft with my socket wrench.
So, I suppose i need to buy or rent a tool...any recommendations? i don't have a compressor but I suppose i could rent that also.

Impact wrench, breaker bar, ??

Is heating up the bolt with a propane torch worth a try?

thanks for the help!!

raise up the car higher and use a longer breaker bar.

Heating up the nut with a propane torch may be worth a try if all else fails, but before you strip the nut.*

my advice, if you heat up that bolt to loosen it up, replace it. heating it up will destroy the temper and being on the driveshaft makes it a critical part. like james said, use a longer breaker bar along with a 6 point socket if youre able to.

breaker bar is the way to go. lots of leverage.

breaker bar is really your only way. might want to try a lube before heating although the seal is most likely too tight for any lube to get in.
