Did you try the bottle jack trick?

No. I've been away at work. And I don't have a decent bottle jack. I did try to get the trolley jack under, but there's too much in the way for that.

I tried 3/4 breaker bar and a 2m pipe and my 110kg frame and couldn't budge my bolt on the 4bd1, so bought a Milwaukee 18v 3/4 drive rattle gun with 1627Nm of torque, came straight off! My 1/2" rattle gun was laughed at😊

110kg at 2m in 9.8m/s/s of gravity, if aligned correctly, works out at 2156nm.

Amazing how stubborn bolts can be. I could not shift the wheel nuts on a tipper truck I dont know what they put them on with. I had a 7 foot pipe on the bar and I was bouncing on it, gripping the side of the truck on the downward bounce and helping my weight pushing with all my strength. Eventually the first one let go with a crack!! No idea how many foot pound it was but it must have been a LOT.

Did I mention beer may have been involved

.

(It was also on an engine stand so full body weight may not have been fully involved! Did I mention the beer bit?)

I had a truck driver break one of my 3/4 drive sockets (without my permission) doing exactly what you described, trouble was this dill didn't know that the wheel nuts on the left hand side of the truck were left hand thread, pays to check first, Regards Frank.

No mine were normal threads, but you make a very good point though.

Years ago, my sister came to my then workplace with a tale of woe. She had a flat tyre in a big shopping centre. A man had tried to help her

. He said that there
was "something wrong" with her wheel nuts, after he had been jumping up and down on her wheel brace. It was on the LHF wheel of her VG Valiant.
I eventually got them undone by putting a long breaker bar on and wedging it on the ground and driving it forward gently.
The bloody studs even had a big "L" stamped into the top. Still, it's hard to blame him. The other two of the "Big Three" at the time didn't use left hand thread on their wheel nuts,
or anywhere else for that matter.
There was a theory that wheel nuts would 'undo' if RH threads were used on the LH side of the car/truck. It's an interesting theory.
The Scania I drive has all RH thread wheel nuts, and it makes no difference; I can't undo the things either way. If I get a flat I have to wait for the tyre guy.
