Pitman Arm Nut Torque

Does anybody know HOW to torque down a nut this size to 450 lb??

Will an air wrench do it? NOBODY around here has a torque wrench that goes up to 450 lb...

The torque multiplier Steve mentioned is the accurate and proper way. The less accurate way....a 2 foot breaker bar with 225lbs hanging on the end of it (or 3ft with 150lbs, etc).

Have you checked with any local heavy truck repair or tire shops that you may have around you? They are more likely to have torque wrenches with that capability. A regular car/truck mechanic is not likely to have one due to the lack of need and the high cost. Our heavy truck mechanic has a couple of them. He has one that goes up to 600 lb-ft that is a 3/4" drive and is about 3 1/2 feet long. Cost was around $700. The other is even larger...

BTW... Where did you come up with the 450 lb-ft number? Ford specs the '08 F-250/350 sector (pitman) arm shaft nut at 350 lb-ft (475 Nm) and the inner drag link nut at 129 lb-ft (175 Nm)

wow...

Where di you get that information? I "thought" the Frod Tech told us 450 lb but I could be mistaken. Going Monday mroning to have a new bolt put on with an entire tube of locktite. Hopefully it will be the FINAL time....

Also need info on where to get a programmer to fix my truck to 37" tires. All I see only goes to 35".
