Yes,we have several of them at work. On a car it will come loose or bust the stud . On big trucks it can get tireing as it is a huge multiplyer. They do perform as advertised.

Not going to comment about large trucks that the tire guys have hammered the lug nuts on with i inch drive air tools, but in my experience a 3/4 inch drive breaker bar even without cheater pipt will either take off the lug nuts or wring off the stud. I something like the 3/4 drive ratchet(nice, I have one also) or a breaker bar has to be used to run the nuts all the way off on all lugs then all the studs need tobe replaced.

That is a torque multiplier, it is useful for certain application where you need high torque but without access to an air compressor. That is an older design, the newer designs do not use a foot as a reaction.

A 3/4" or 1" ratchet with a long handle will likely be enough for you to remove the lug nuts.

If you have inner and outer nuts on your truck (BUDD wheels), remember that the LEFT side is LEFT handed threads and the RIGHT side is RIGHT handed threads. Don't mix them up!

Just get a long breaker bar. HF or Autozone has them for about $20. That thing seems much more awkward.

I had a breaker bar from harbor freight a 3/4" i think and with the handle of my jack I broke the breaker bar. It was brand new.

Im thinking either this thing or a 1" impact from harbor freight.

The pin or bolt on those ****!!!
I replaced mine with a bolt and nut, never had an issue since and broken dozens of stubborn lugs free!

On the budd wheels I've had to resort to the torch and heat the wheel up to get the damn things off. A lot of times if you hit the wheel around the area of the lug with a sledge it will help to loosen it up. I'll use PBlaster/sledge/1" impact, PBlaster/sledge/1"impact multiple times before I go to the torch. I work on School Buses and the rears get snug.

I've had lugs stand up a ir 1" impact at work on several occasions. Try using a map torch and heating the lugs up that should help!

I'm talking about semi trailer lugs though

What are you working on so we can get an idea?

Maybe go in for a tire rotation and make sure the set the torques properly? Otherwise, I'd probably stick to a really long breaker bar.

+1 for drop of oil on each stud.

Hit up pawn shop for long break-over bar with short extension and socket. Just keep the bar behind the seat and leave in truck at all times.

Left hand lug nuts on the left check for an L at the end of the stud and yes they are torqued very high you may need a 1 inch impact wrench to loosen them.

Normally I'd say an IR W7150 or Milwaukee 2763 can handle it, but I think the OP is talking about a medium or heavy duty commercial truck, in which case he may, in fact, need a torque multiplier to reliably break the lugs loose.

You have to be careful when recommending that someone apply heat to a tire rim, whether it's the lug nuts or the rim itself. Heat can cause a tire to suddenly explode without warning. It probably doesn't happen often, but when it does happen, it's lethal.

It's explained in this video.

I was always told that any type of lubricant on wheel studs allows for over torquing and may lead to failure/breakage. Dry is how I have always installed lug nuts and will continue to do so. Stuck lug nuts? Wouldn't ever spend the money on an expensive tool like a torque multiplier. Have never seen the lug nut that won't come off with my 3/4" breaker bar.

Years ago my Dad had my younger brother and his buddy change the brakes on a military 5 ton truck. They got the wheels from one side off, but had a problem with the other side. They ended up taking a lot of heat and a 1" impact. They came off, but only because of the heat. That was when they learned about backwards threads on trucks. All of the lug nuts and studs had to be replaced. Not all trucks are like this, but as others have said they should have an L on the tip of the stud.

Torque is like 300 -450 ft lbs for that truck

Yes, it helps if you know what you're doing. It doesn't take a great deal of heat in order to loosen up the lug. Not enough to spread to the tire actually. The wheel and drum make a nice heat sink. I rarely have problems with the outside nuts on Budd wheels, it's the inside that tend to lock up and imo the heat should be applied to the rim in that case. All it takes is a small amount around the outside area of the lug seat then hit it with the inch impact. If it doesn't break loose wait a bit and repeat. Use your hand as a temp tester to see if heat is creeping to the tire area.

Ive been on the road for 19 hours. Long Island to mississippi thats why no reply. It is a 06 isuzu npr box truck. It has I think the 41mm lugs. I had a 3/4 harbor freight breaker bar that broke flush at the socket after I put a 4 foot jack handle on it.
Im kinda leaning towards the 1" harbor freight impact. Someone suggested the Milwaukee cordless. I probably would get that if I knew for sure it would get them off but I don't want to take that chance.
Thanks for all the replys Still thinking which way I want to go

41 mm nut I believe has a torque of 375 ftlbs . Way more then a cordless will do. A 3/4 dive air gun will be more then required, a half gun would put them on fine but may not bget them off after road corrosion sets in.

That would work!
A bit pricey IMO, but you'd be hard pressed to find a lug that won't break free.

I have the older bulkier version, I think is 400# torque. Never really had an issue and only a couple times I needed a breaker bar to free the lugs.
This was with daily use swapping tires so it was up against a wide range of scenarios from brand new cars to old rusty POS's.

Gentlemen!

We know for a fact that even the cheapest of 1/2" ratchets from China and Taiwan can take north of 500 lb/ft, even over 700. (ratchet test by some 4-wheel magazine if memory serves me)

I don't have corresponding numbers for cheap 3/4" breaker bars - but I think it's safe to say that since the OP has already broken the anvil of 3/4" HF bar he needs something capable of 1500lb/ft + or plenty of heat to have a decent chance of removing said nuts. Actually there is no way to know how stuck they are. Something heavy duty with 1" anvil....

I would take the truck to a tire shop and have them loosen up all the lugs. Coat in anti seize and tighten them back on correctly. After that I would go and buy a decent 3/4 breaker bar that should do the job under normal circumstances.
