...same here. set my torque wrench at 150# (max setting), and gave it "just a little more". figure i got to be in the 165 ballpark. BTW, i'm reading you guys trying to wrench those 36mm spindle nuts off. if you have an air compresser, (if not, you should buy one!) - get a 1/2 inch drive impact wrench, and a axle nut socket. it will take those axle nuts off like a hot knife going through butter, as well as those peskey T-55 cap screws.

YEAH, that's the "correct'' way.......truth being told I used 3/4" drive stuff to remove. Guesstimated once past 150 on 1/2"drive t.wrench figured I was close. Thought about buying one that goes up to 250, untill I saw the price, all I could think was what motor parts I could buying with the same money.
I do love the stories about 4 foot fence poles etc......mine is a front shock tube off a harley I had

My passenger side came off so easy using the 1/2" breaker bar I then went over to the driver side, I snaped the first extension with no cheater pipe, I had a short two foot pipe that I broke the second one with, I then got mad and got out the 3/4" drive with the 8' bar and that took it right off, but I thought the car was going to climb over the wheel blocks when I took it off, I diffently see what you mean by no flex in the 3/4" drive system, amazing the difference.

I tried my IR titanium and it just basically said you want me to do what? Just sat there and did nothing.

Although I wished I had used an impact wrench, I managed to get mine off with an 18" Craftsman 1/2" breaker and a rented AutoZone socket...some jumping required .

Default Dead Horse?

Hello,
Noticed some of the fellas are on line tonite. Been reading previous threads. So not to open a new one. I have my 92 LT1 a/t 81k mi.up on jacks. I have removed the large axle nut, With impact. The torx 55's are no picnic. I have put PB blaster 5 or 6 times, let it soak over-nite.Heated the threads cleaned them. looked to make sure they do appear to be right hand threads. Have put an 1/2" impact on them. Will lift the hub to get at the top one. The Haynes says to take the tie rod off. Please advise. I'm sure I missed something. Really greatful to our forum. Thanks in advance. Larry

No need to remove tie rods, the T55's are removed counter-clockwise. Sometimes if you give it a quick jerk in the clockwise (tighten) and then reverse it they come loose if they are stubborn.
You may have to move the driveshaft a bit to get the socket on there, terrible leverage points!

Thank you brother. Man it is a terrible spot on top. Headed out to the garage now. I kind of thought the Haynes was full of it. There are some helpfull pictures sometimes, that the red and white manual doesn't have. You gave me enough confidence to try it again. Thanks Larry.

I can't believe you got both rear bearings off without any of those torx bolts stripping.

Hi,
Removed them after 3 days of trying. The heads of the bolts do look a little worn on the remove side. I soaked them for days with PB blaster and heated them with a propane torch. The impact wrench would not remove the two I coould get it on. Cuisinartvette was right. Just a lot of effort. I didn't use a cheater bar, couldn't get the car high enough. Put it all back together and it still clicks. Checked it out on another thread. It seems there is a washer that can be changed. The teflon wears off and then it clicks.I'll post the thread here later.
Thanks lbreen

Some say the surface rust on the splines (end of axles) causes this-Put a little lube on them....I didnt replace the washer either, no clicks though.
